how to make a bibliography for a research paper

How to Write a Bibliography for a Research Paper

Do not try to “wow” your instructor with a long bibliography when your instructor requests only a works cited page. It is tempting, after doing a lot of work to research a paper, to try to include summaries on each source as you write your paper so that your instructor appreciates how much work you did. That is a trap you want to avoid. MLA style, the one that is most commonly followed in high schools and university writing courses, dictates that you include only the works you actually cited in your paper—not all those that you used.

• If your assignment calls for a bibliography, list all the sources you consulted in your research.
• If your assignment calls for a works cited or references page, include only the sources you quote, summarize, paraphrase, or mention in your paper.
• If your works cited page includes a source that you did not cite in your paper, delete it.
• All in-text citations that you used at the end of quotations, summaries, and paraphrases to credit others for their ideas,words, and work must be accompanied by a cited reference in the bibliography or works cited. These references must include specific information about the source so that your readers can identify precisely where the information came from.The citation entries on a works cited page typically include the author’s name, the name of the article, the name of the publication, the name of the publisher (for books), where it was published (for books), and when it was published.

The good news is that you do not have to memorize all the many ways the works cited entries should be written. Numerous helpful style guides are available to show you the information that should be included, in what order it should appear, and how to format it. The format often differs according to the style guide you are using. The Modern Language Association (MLA) follows a particular style that is a bit different from APA (American Psychological Association) style, and both are somewhat different from the Chicago Manual of Style (CMS). Always ask your teacher which style you should use.

A bibliography usually appears at the end of a paper on its own separate page. All bibliography entries—books, periodicals, Web sites, and nontext sources such radio broadcasts—are listed together in alphabetical order. Books and articles are alphabetized by the author’s last name.

Most teachers suggest that you follow a standard style for listing different types of sources. If your teacher asks you to use a different form, however, follow his or her instructions. Take pride in your bibliography. It represents some of the most important work you’ve done for your research paper—and using proper form shows that you are a serious and careful researcher.

Bibliography Entry for a Book

A bibliography entry for a book begins with the author’s name, which is written in this order: last name, comma, first name, period. After the author’s name comes the title of the book. If you are handwriting your bibliography, underline each title. If you are working on a computer, put the book title in italicized type. Be sure to capitalize the words in the title correctly, exactly as they are written in the book itself. Following the title is the city where the book was published, followed by a colon, the name of the publisher, a comma, the date published, and a period. Here is an example:

Format : Author’s last name, first name. Book Title. Place of publication: publisher, date of publication.

• A book with one author : Hartz, Paula.  Abortion: A Doctor’s Perspective, a Woman’s Dilemma . New York: Donald I. Fine, Inc., 1992.
• A book with two or more authors : Landis, Jean M. and Rita J. Simon.  Intelligence: Nature or Nurture?  New York: HarperCollins, 1998.

Bibliography Entry for a Periodical

A bibliography entry for a periodical differs slightly in form from a bibliography entry for a book. For a magazine article, start with the author’s last name first, followed by a comma, then the first name and a period. Next, write the title of the article in quotation marks, and include a period (or other closing punctuation) inside the closing quotation mark. The title of the magazine is next, underlined or in italic type, depending on whether you are handwriting or using a computer, followed by a period. The date and year, followed by a colon and the pages on which the article appeared, come last. Here is an example:

Format:  Author’s last name, first name. “Title of the Article.” Magazine. Month and year of publication: page numbers.

• Article in a monthly magazine : Crowley, J.E.,T.E. Levitan and R.P. Quinn.“Seven Deadly Half-Truths About Women.”  Psychology Today  March 1978: 94–106.
• Article in a weekly magazine : Schwartz, Felice N.“Management,Women, and the New Facts of Life.”  Newsweek  20 July 2006: 21–22.
• Signed newspaper article : Ferraro, Susan. “In-law and Order: Finding Relative Calm.”  The Daily News  30 June 1998: 73.
• Unsigned newspaper article : “Beanie Babies May Be a Rotten Nest Egg.”  Chicago Tribune  21 June 2004: 12.

Bibliography Entry for a Web Site

For sources such as Web sites include the information a reader needs to find the source or to know where and when you found it. Always begin with the last name of the author, broadcaster, person you interviewed, and so on. Here is an example of a bibliography for a Web site:

Format : Author.“Document Title.” Publication or Web site title. Date of publication. Date of access.

Example : Dodman, Dr. Nicholas. “Dog-Human Communication.”  Pet Place . 10 November 2006.  23 January 2014 < http://www.petplace.com/dogs/dog-human-communication-2/page1.aspx >

After completing the bibliography you can breathe a huge sigh of relief and pat yourself on the back. You probably plan to turn in your work in printed or handwritten form, but you also may be making an oral presentation. However you plan to present your paper, do your best to show it in its best light. You’ve put a great deal of work and thought into this assignment, so you want your paper to look and sound its best. You’ve completed your research paper!

How to Write a Bibliography (MLA, APA Examples)

Learn how to easily write a bibliography by following the format outlined in this article.

This resource will help your students properly cite different resources in the bibliography of a research paper, and how to format those citations, for books, encyclopedias, films, websites, and people.

What is a bibliography?

According to Infoplease.com, A bibliography is a list of the types of sources you used to get information for your report. It is included at the end of your report, on the last page (or last few pages).

What are the types of bibliography styles (MLA, APA, etc.)?

The 3 most common bibliography/citation styles are:

• MLA Style: The Modern Language Association works cited page style
• APA Style: The American Psychological Association style
• Chicago Style: The bibliography style defined by the Chicago Manual of Style

We’ll give examples of how to create bibliography entries in various styles further down in this article. 

What sources do you put in a bibliography?

An annotated bibliography should include a reference list of any sources you use in writing a research paper. Any printed sources from which you use a text citation, including books, websites, newspaper articles, journal articles, academic writing, online sources (such as PDFs), and magazines should be included in a reference list. In some cases, you may need or want to cite conversations or interviews, works of art, visual works such as movies, television shows, or documentaries - these (and many others) can also be included in a reference list.

How to get started writing your bibliography

You will find it easier to prepare your MLA, APA, or Chicago annotated bibliography if you keep track of each book, encyclopedia, journal article, webpage or online source you use as you are reading and taking notes. Start a preliminary, or draft, bibliography by listing on a separate sheet of paper all your sources. Note down the full title, author’s last name, place of publication, web address, publisher, and date of publication for each source.

Sample Bibliography

An APA format bibliography lists all of the sources that might be used in a paper. A bibliography can be a great tool to help you keep track of information during the research and writing process. In some cases, your instructor may require you to include a bibliography as part of your assignment.

At a Glance

A well-written APA format bibliography can help you keep track of information and sources as you research and write your psychology paper. To create a bibliography, gather up all of the sources that you might use in your paper. Create an APA format reference for each source and then write a brief annotation. Your annotation should be a brief summary of what each reference is about. You can quickly refer to these annotations When writing your paper and determine which to include.

What Is an APA Format Bibliography?

An APA format bibliography is an alphabetical listing of all sources that might be used to write an academic paper, essay, article, or research paper—particularly work that is covering psychology or psychology-related topics. APA format is the official style of the American Psychological Association (APA). This format is used by many psychology professors, students, and researchers.

Even if it is not a required part of your assignment, writing a bibliography can help you keep track of your sources and make it much easier to create your final reference page in proper APA format.

Creating an APA Bibliography

A bibliography is similar in many ways to a reference section , but there are some important differences. While a reference section includes every source that was actually used in your paper, a bibliography may include sources that you considered using but may have dismissed because they were irrelevant or outdated.

Bibliographies can be a great way to keep track of information you might want to use in your paper and to organize the information that you find in different sources. The following are four steps you can follow to create your APA format bibliography.

Start on a New Page

Your working bibliography should be kept separate from the rest of your paper. Start it on a new page, with the title "Bibliography" centered at the top and in bold text. Some people use the title "References" instead, so it's best to check with your professor or instructor about which they prefer you to use.

Gather Your Sources

Compile all the sources you might possibly use in your paper. While you might not use all of these sources in your paper, having a complete list will make it easier later on when you prepare your reference section.

Gathering your sources can be particularly helpful when outlining and writing your paper.

By quickly glancing through your working bibliography, you will be able to get a better idea of which sources will be the most appropriate to support your thesis and main points.

Reference Each Source

Your references should be listed alphabetically by the author’s last name, and they should be double-spaced. The first line of each reference should be flush left, while each additional line of a single reference should be a few spaces to the right of the left margin, which is known as a hanging indent.

The format of each source is as follows for academic journals:

• Last name of first author (followed by their first initial)
• The year the source was published in parentheses
• The title of the source
• The journal that published the source (in italics)
• The volume number, if applicable (in italics)
• The issue number, if applicable
• Page numbers (in parentheses)
• The URL or "doi" in lowercase letters followed by a colon and the doi number, if applicable

The following examples are scholarly articles in academic journals, cited in APA format:

• Kulacaoglu, F., & Kose, S. (2018). Borderline personality disorder (BPD): In the midst of vulnerability, chaos, and awe.  Brain sciences ,  8 (11), 201. doi:10.3390/brainsci8110201
• Cattane, N., Rossi, R., & Lanfredi, M. (2017). Borderline personality disorder and childhood trauma: exploring the affected biological systems and mechanisms.  BMC Psychiatry,   18 (221). doi:10.1186/s12888-017-1383-2

Visit the American Psychological Association's website for more information on citing other types of sources including online media, audiovisual media, and more.

Create an Annotation for Each Source

Normally a bibliography contains only references' information, but in some cases you might decide to create an annotated bibliography. An annotation is a summary or evaluation of the source.

An annotation is a brief description of approximately 150 words describing the information in the source, your evaluation of its credibility, and how it pertains to your topic. Writing one of these for each piece of research will make your writing process faster and easier.

This step helpful in determining which sources to ultimately use in your paper. Your instructor may also require it as part of the assignment so they can assess your thought process and understanding of your topic.

Reasons to Write a Bibliography

One of the biggest reasons to create an APA format bibliography is simply to make the research and writing process easier.

If you do not have a comprehensive list of all of your references, you might find yourself scrambling to figure out where you found certain bits of information that you included in your paper.

A bibliography is also an important tool that your readers can use to access your sources.

While writing an annotated bibliography might not be required for your assignment, it can be a very useful step. The process of writing an annotation helps you learn more about your topic, develop a deeper understanding of the subject, and become better at evaluating various sources of information.

The following is an example of an APA format bibliography by the website EasyBib:

There are many online resources that demonstrate different formats of bibliographies, including the American Psychological Association website . Purdue University's Online Writing Lab also has examples of formatting an APA format bibliography.

Check out this video on their YouTube channel which provides detailed instructions on formatting an APA style bibliography in Microsoft Word.

You can check out the Purdue site for more information on writing an annotated APA bibliography as well.

What This Means For You

If you are taking a psychology class, you may be asked to create a bibliography as part of the research paper writing process. Even if your instructor does not expressly require a bibliography, creating one can be a helpful way to help structure your research and make the writing process more manageable.

For psychology majors , it can be helpful to save any bibliographies you have written throughout your studies so that you can refer back to them later when studying for exams or writing papers for other psychology courses.

If you are using Chicago style footnotes or endnotes, you should include a bibliography at the end of your paper that provides complete citation information for all of the sources you cite in your paper. Bibliography entries are formatted differently from notes. For bibliography entries, you list the sources alphabetically by last name, so you will list the last name of the author or creator first in each entry. You should single-space within a bibliography entry and double-space between them. When an entry goes longer than one line, use a hanging indent of .5 inches for subsequent lines. Here’s a link to a sample bibliography that shows layout and spacing . You can find a sample of note format here .

Complete note vs. shortened note

Here’s an example of a complete note and a shortened version of a note for a book:

1. Karen Ho, Liquidated: An Ethnography of Wall Street (Durham: Duke University Press, 2009), 27-35.

1. Karen Ho, Liquidated , 27-35.

Note vs. Bibliography entry

The bibliography entry that corresponds with each note is very similar to the longer version of the note, except that the author’s last and first name are reversed in the bibliography entry. To see differences between note and bibliography entries for different types of sources, check this section of the Chicago Manual of Style .

For Liquidated , the bibliography entry would look like this:

Ho, Karen, Liquidated: An Ethnography of Wall Street . Durham: Duke University Press, 2009.

Citing a source with two or three authors

If you are citing a source with two or three authors, list their names in your note in the order they appear in the original source. In the bibliography, invert only the name of the first author and use “and” before the last named author.

1. Melissa Borja and Jacob Gibson, “Internationalism with Evangelical Characteristics: The Case of Evangelical Responses to Southeast Asian Refugees,” The Review of Faith & International Affairs 17, no. 3 (2019): 80-81, https://doi.org/10.1080/15570274.2019.1643983 .

Shortened note:

1. Borja and Gibson, “Internationalism with Evangelical Characteristics,” 80-81.

Bibliography:

Citing a source with more than three authors

If you are citing a source with more than three authors, include all of them in the bibliography, but only include the first one in the note, followed by et al. ( et al. is the shortened form of the Latin et alia , which means “and others”).

1. Justine M. Nagurney, et al., “Risk Factors for Disability After Emergency Department Discharge in Older Adults,” Academic Emergency Medicine 27, no. 12 (2020): 1271.

Short version of note:

1. Justine M. Nagurney, et al., “Risk Factors for Disability,” 1271.

Citing a book consulted online

If you are citing a book you consulted online, you should include a URL, DOI, or the name of the database where you found the book.

1. Karen Ho, Liquidated: An Ethnography of Wall Street (Durham: Duke University Press, 2009), 27-35, https://doi-org.ezp-prod1.hul.harvard.edu/10.1215/9780822391371 .

Citing an e-book consulted outside of a database

If you are citing an e-book that you accessed outside of a database, you should indicate the format. If you read the book in a format without fixed page numbers (like Kindle, for example), you should not include the page numbers that you saw as you read. Instead, include chapter or section numbers, if possible.

A Quick Guide to Harvard Referencing | Citation Examples

Published on 14 February 2020 by Jack Caulfield . Revised on 15 September 2023.

Referencing is an important part of academic writing. It tells your readers what sources you’ve used and how to find them.

Harvard is the most common referencing style used in UK universities. In Harvard style, the author and year are cited in-text, and full details of the source are given in a reference list .

Harvard in-text citation, creating a harvard reference list, harvard referencing examples, referencing sources with no author or date, frequently asked questions about harvard referencing.

A Harvard in-text citation appears in brackets beside any quotation or paraphrase of a source. It gives the last name of the author(s) and the year of publication, as well as a page number or range locating the passage referenced, if applicable:

Note that ‘p.’ is used for a single page, ‘pp.’ for multiple pages (e.g. ‘pp. 1–5’).

An in-text citation usually appears immediately after the quotation or paraphrase in question. It may also appear at the end of the relevant sentence, as long as it’s clear what it refers to.

When your sentence already mentions the name of the author, it should not be repeated in the citation:

Sources with multiple authors

When you cite a source with up to three authors, cite all authors’ names. For four or more authors, list only the first name, followed by ‘ et al. ’:

Sources with no page numbers

Some sources, such as websites , often don’t have page numbers. If the source is a short text, you can simply leave out the page number. With longer sources, you can use an alternate locator such as a subheading or paragraph number if you need to specify where to find the quote:

Multiple citations at the same point

When you need multiple citations to appear at the same point in your text – for example, when you refer to several sources with one phrase – you can present them in the same set of brackets, separated by semicolons. List them in order of publication date:

Multiple sources with the same author and date

If you cite multiple sources by the same author which were published in the same year, it’s important to distinguish between them in your citations. To do this, insert an ‘a’ after the year in the first one you reference, a ‘b’ in the second, and so on:

A bibliography or reference list appears at the end of your text. It lists all your sources in alphabetical order by the author’s last name, giving complete information so that the reader can look them up if necessary.

The reference entry starts with the author’s last name followed by initial(s). Only the first word of the title is capitalised (as well as any proper nouns).

Sources with multiple authors in the reference list

As with in-text citations, up to three authors should be listed; when there are four or more, list only the first author followed by ‘ et al. ’:

Reference list entries vary according to source type, since different information is relevant for different sources. Formats and examples for the most commonly used source types are given below.

• Entire book
• Book chapter
• Translated book
• Edition of a book

Journal articles

• Print journal
• Online-only journal with DOI
• Online-only journal with no DOI
• General web page
• Online article or blog
• Social media post

Sometimes you won’t have all the information you need for a reference. This section covers what to do when a source lacks a publication date or named author.

No publication date

When a source doesn’t have a clear publication date – for example, a constantly updated reference source like Wikipedia or an obscure historical document which can’t be accurately dated – you can replace it with the words ‘no date’:

Note that when you do this with an online source, you should still include an access date, as in the example.

When a source lacks a clearly identified author, there’s often an appropriate corporate source – the organisation responsible for the source – whom you can credit as author instead, as in the Google and Wikipedia examples above.

When that’s not the case, you can just replace it with the title of the source in both the in-text citation and the reference list:

Prevent plagiarism, run a free check.

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

A Harvard in-text citation should appear in brackets every time you quote, paraphrase, or refer to information from a source.

The citation can appear immediately after the quotation or paraphrase, or at the end of the sentence. If you’re quoting, place the citation outside of the quotation marks but before any other punctuation like a comma or full stop.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

Though the terms are sometimes used interchangeably, there is a difference in meaning:

• A reference list only includes sources cited in the text – every entry corresponds to an in-text citation .
• A bibliography also includes other sources which were consulted during the research but not cited.

How to Cite Sources

Here is a complete list for how to cite sources. Most of these guides present citation guidance and examples in MLA, APA, and Chicago.

If you’re looking for general information on MLA or APA citations , the EasyBib Writing Center was designed for you! It has articles on what’s needed in an MLA in-text citation , how to format an APA paper, what an MLA annotated bibliography is, making an MLA works cited page, and much more!

MLA Format Citation Examples

The Modern Language Association created the MLA Style, currently in its 9th edition, to provide researchers with guidelines for writing and documenting scholarly borrowings.  Most often used in the humanities, MLA style (or MLA format ) has been adopted and used by numerous other disciplines, in multiple parts of the world.

MLA provides standard rules to follow so that most research papers are formatted in a similar manner. This makes it easier for readers to comprehend the information. The MLA in-text citation guidelines, MLA works cited standards, and MLA annotated bibliography instructions provide scholars with the information they need to properly cite sources in their research papers, articles, and assignments.

APA Format Citation Examples

The American Psychological Association created the APA citation style in 1929 as a way to help psychologists, anthropologists, and even business managers establish one common way to cite sources and present content.

APA is used when citing sources for academic articles such as journals, and is intended to help readers better comprehend content, and to avoid language bias wherever possible. The APA style (or APA format ) is now in its 7th edition, and provides citation style guides for virtually any type of resource.

Chicago Style Citation Examples

The Chicago/Turabian style of citing sources is generally used when citing sources for humanities papers, and is best known for its requirement that writers place bibliographic citations at the bottom of a page (in Chicago-format footnotes ) or at the end of a paper (endnotes).

The Turabian and Chicago citation styles are almost identical, but the Turabian style is geared towards student published papers such as theses and dissertations, while the Chicago style provides guidelines for all types of publications. This is why you’ll commonly see Chicago style and Turabian style presented together. The Chicago Manual of Style is currently in its 17th edition, and Turabian’s A Manual for Writers of Research Papers, Theses, and Dissertations is in its 8th edition.

6 Interesting Citation Facts

The world of citations may seem cut and dry, but there’s more to them than just specific capitalization rules, MLA in-text citations , and other formatting specifications. Citations have been helping researches document their sources for hundreds of years, and are a great way to learn more about a particular subject area.

Ever wonder what sets all the different styles apart, or how they came to be in the first place? Read on for some interesting facts about citations!

1. There are Over 7,000 Different Citation Styles

You may be familiar with MLA and APA citation styles, but there are actually thousands of citation styles used for all different academic disciplines all across the world. Deciding which one to use can be difficult, so be sure to ask you instructor which one you should be using for your next paper.

2. Some Citation Styles are Named After People

While a majority of citation styles are named for the specific organizations that publish them (i.e. APA is published by the American Psychological Association, and MLA format is named for the Modern Language Association), some are actually named after individuals. The most well-known example of this is perhaps Turabian style, named for Kate L. Turabian, an American educator and writer. She developed this style as a condensed version of the Chicago Manual of Style in order to present a more concise set of rules to students.

3. There are Some Really Specific and Uniquely Named Citation Styles

How specific can citation styles get? The answer is very. For example, the “Flavour and Fragrance Journal” style is based on a bimonthly, peer-reviewed scientific journal published since 1985 by John Wiley & Sons. It publishes original research articles, reviews and special reports on all aspects of flavor and fragrance. Another example is “Nordic Pulp and Paper Research,” a style used by an international scientific magazine covering science and technology for the areas of wood or bio-mass constituents.

4. More citations were created on  EasyBib.com  in the first quarter of 2018 than there are people in California.

The US Census Bureau estimates that approximately 39.5 million people live in the state of California. Meanwhile, about 43 million citations were made on EasyBib from January to March of 2018. That’s a lot of citations.

5. “Citations” is a Word With a Long History

The word “citations” can be traced back literally thousands of years to the Latin word “citare” meaning “to summon, urge, call; put in sudden motion, call forward; rouse, excite.” The word then took on its more modern meaning and relevance to writing papers in the 1600s, where it became known as the “act of citing or quoting a passage from a book, etc.”

6. Citation Styles are Always Changing

The concept of citations always stays the same. It is a means of preventing plagiarism and demonstrating where you relied on outside sources. The specific style rules, however, can and do change regularly. For example, in 2018 alone, 46 new citation styles were introduced , and 106 updates were made to exiting styles. At EasyBib, we are always on the lookout for ways to improve our styles and opportunities to add new ones to our list.

Why Citations Matter

Here are the ways accurate citations can help your students achieve academic success, and how you can answer the dreaded question, “why should I cite my sources?”

They Give Credit to the Right People

Citing their sources makes sure that the reader can differentiate the student’s original thoughts from those of other researchers. Not only does this make sure that the sources they use receive proper credit for their work, it ensures that the student receives deserved recognition for their unique contributions to the topic. Whether the student is citing in MLA format , APA format , or any other style, citations serve as a natural way to place a student’s work in the broader context of the subject area, and serve as an easy way to gauge their commitment to the project.

They Provide Hard Evidence of Ideas

Having many citations from a wide variety of sources related to their idea means that the student is working on a well-researched and respected subject. Citing sources that back up their claim creates room for fact-checking and further research . And, if they can cite a few sources that have the converse opinion or idea, and then demonstrate to the reader why they believe that that viewpoint is wrong by again citing credible sources, the student is well on their way to winning over the reader and cementing their point of view.

They Promote Originality and Prevent Plagiarism

The point of research projects is not to regurgitate information that can already be found elsewhere. We have Google for that! What the student’s project should aim to do is promote an original idea or a spin on an existing idea, and use reliable sources to promote that idea. Copying or directly referencing a source without proper citation can lead to not only a poor grade, but accusations of academic dishonesty. By citing their sources regularly and accurately, students can easily avoid the trap of plagiarism , and promote further research on their topic.

They Create Better Researchers

By researching sources to back up and promote their ideas, students are becoming better researchers without even knowing it! Each time a new source is read or researched, the student is becoming more engaged with the project and is developing a deeper understanding of the subject area. Proper citations demonstrate a breadth of the student’s reading and dedication to the project itself. By creating citations, students are compelled to make connections between their sources and discern research patterns. Each time they complete this process, they are helping themselves become better researchers and writers overall.

When is the Right Time to Start Making Citations?

Make in-text/parenthetical citations as you need them.

As you are writing your paper, be sure to include references within the text that correspond with references in a works cited or bibliography. These are usually called in-text citations or parenthetical citations in MLA and APA formats. The most effective time to complete these is directly after you have made your reference to another source. For instance, after writing the line from Charles Dickens’ A Tale of Two Cities : “It was the best of times, it was the worst of times…,” you would include a citation like this (depending on your chosen citation style):

(Dickens 11).

This signals to the reader that you have referenced an outside source. What’s great about this system is that the in-text citations serve as a natural list for all of the citations you have made in your paper, which will make completing the works cited page a whole lot easier. After you are done writing, all that will be left for you to do is scan your paper for these references, and then build a works cited page that includes a citation for each one.

2. Understand the General Formatting Rules of Your Citation Style Before You Start Writing

While reading up on paper formatting may not sound exciting, being aware of how your paper should look early on in the paper writing process is super important. Citation styles can dictate more than just the appearance of the citations themselves, but rather can impact the layout of your paper as a whole, with specific guidelines concerning margin width, title treatment, and even font size and spacing. Knowing how to organize your paper before you start writing will ensure that you do not receive a low grade for something as trivial as forgetting a hanging indent.

Don’t know where to start? Here’s a formatting guide on APA format .

3. Double-check All of Your Outside Sources for Relevance and Trustworthiness First

Collecting outside sources that support your research and specific topic is a critical step in writing an effective paper. But before you run to the library and grab the first 20 books you can lay your hands on, keep in mind that selecting a source to include in your paper should not be taken lightly. Before you proceed with using it to backup your ideas, run a quick Internet search for it and see if other scholars in your field have written about it as well. Check to see if there are book reviews about it or peer accolades. If you spot something that seems off to you, you may want to consider leaving it out of your work. Doing this before your start making citations can save you a ton of time in the long run.

Finished with your paper? It may be time to run it through a grammar and plagiarism checker , like the one offered by EasyBib Plus. If you’re just looking to brush up on the basics, our grammar guides  are ready anytime you are.

How To Write a Bibliography (3 Styles, Plus Examples)

Give credit where credit is due.

Writing a research paper involves a lot of work. Students need to consult a variety of sources to gather reliable information and ensure their points are well supported. Research papers include a bibliography, which can be a little tricky for students. Learn how to write a bibliography in multiple styles and find basic examples below.

IMPORTANT: Each style guide has its own very specific rules, and they often conflict with one another. Additionally, each type of reference material has many possible formats, depending on a variety of factors. The overviews shown here are meant to guide students in writing basic bibliographies, but this information is by no means complete. Students should always refer directly to the preferred style guide to ensure they’re using the most up-to-date formats and styles.

What is a bibliography?

When you’re researching a paper, you’ll likely consult a wide variety of sources. You may quote some of these directly in your work, summarize some of the points they make, or simply use them to further the knowledge you need to write your paper. Since these ideas are not your own, it’s vital to give credit to the authors who originally wrote them. This list of sources, organized alphabetically, is called a bibliography.

A bibliography should include all the materials you consulted in your research, even if you don’t quote directly from them in your paper. These resources could include (but aren’t limited to):

• Books and e-books
• Periodicals like magazines or newspapers
• Online articles or websites
• Primary source documents like letters or official records

Bibliography vs. References

These two terms are sometimes used interchangeably, but they actually have different meanings. As noted above, a bibliography includes all the materials you used while researching your paper, whether or not you quote from them or refer to them directly in your writing.

A list of references only includes the materials you cite throughout your work. You might use direct quotes or summarize the information for the reader. Either way, you must ensure you give credit to the original author or document. This section can be titled “List of Works Cited” or simply “References.”

Your teacher may specify whether you should include a bibliography or a reference list. If they don’t, consider choosing a bibliography, to show all the works you used in researching your paper. This can help the reader see that your points are well supported, and allow them to do further reading on their own if they’re interested.

Bibliography vs. Citations

Citations refer to direct quotations from a text that are woven into your own writing. There are a variety of ways to write citations, including footnotes and endnotes. These are generally shorter than the entries in a reference list or bibliography. Learn more about writing citations here.

What does a bibliography entry include?

Depending on the reference material, bibliography entries include a variety of information intended to help a reader locate the material if they want to refer to it themselves. These entries are listed in alphabetical order and may include:

• Author/s or creator/s
• Publication date
• Volume and issue numbers
• Publisher and publication city
• Website URL

These entries don’t generally need to include specific page numbers or locations within the work (except for print magazine or journal articles). That type of information is usually only needed in a footnote or endnote citation.

What are the different bibliography styles?

In most cases, writers use one of three major style guides: APA (American Psychological Association), MLA (Modern Language Association), or The Chicago Manual of Style . There are many others as well, but these three are the most common choices for K–12 students.

Many teachers will state their preference for one style guide over another. If they don’t, you can choose your own preferred style. However, you should also use that guide for your entire paper, following their recommendations for punctuation, grammar, and more. This will ensure you are consistent throughout.

Below, you’ll learn how to write a simple bibliography using each of the three major style guides. We’ve included details for books and e-books, periodicals, and electronic sources like websites and videos. If the reference material type you need to include isn’t shown here, refer directly to the style guide you’re using.

APA Style Bibliography and Examples

Source: Verywell Mind

Technically, APA style calls for a list of references instead of a bibliography. If your teacher requires you to use the APA style guide , you can limit your reference list to only items you cite throughout your work.

How To Write a Bibliography (References) Using APA Style

Here are some general notes on writing an APA reference list:

• Title your bibliography section “References” and center the title on the top line of the page.
• Do not center your references; they should be left-aligned. For longer items, subsequent lines should use a hanging indent of 1/2 inch.
• Include all types of resources in the same list.
• Alphabetize your list by author or creator, last name first.
• Do not spell out the author/creator’s first or middle name—only use their initials.
• If there are multiple authors/creators, use an ampersand (&) before the final author/creator.
• Place the date in parentheses.
• Capitalize only the first word of the title and subtitle, unless the word would otherwise be capitalized (proper names, etc.).
• Italicize the titles of books, periodicals, or videos.
• For websites, include the full site information, including the http:// or https:// at the beginning.

Books and E-Books APA Bibliography Examples

For books, APA reference list entries use this format (only include the publisher’s website for e-books):

Last Name, First Initial. Middle Initial. (Publication date). Title with only first word capitalized (unless there’s proper name/noun) . Publisher. Publisher’s website

• Wynn, S. (2020). City of London at war 1939–45 . Pen & Sword Military. https://www.pen-and-sword.co.uk/City-of-London-at-War-193945-Paperback/p/17299

MLA Style Bibliography Examples

Source: Pressbooks

MLA style calls for a Works Cited section, which includes all materials quoted or referred to in your paper. You may also include a Works Consulted section, including other reference sources you reviewed but didn’t directly cite. Together, these constitute a bibliography. If your teacher requests an MLA Style Guide bibliography, ask if you should include Works Consulted as well as Works Cited.

How To Write a Bibliography (Works Cited and Works Consulted) in MLA Style

For both MLA Works Cited and Works Consulted sections, use these general guidelines:

• Start your Works Cited list on a new page. If you include a Works Consulted list, start that on its own new page after the Works Cited section.
• Center the title (Works Cited or Works Consulted) in the middle of the line at the top of the page.
• Align the start of each source to the left margin, and use a hanging indent (1/2 inch) for the following lines of each source.
• Alphabetize your sources using the first word of the citation, usually the author’s last name.
• Include the author’s full name as listed, last name first.
• Capitalize titles using the standard MLA format.
• Leave off the http:// or https:// at the beginning of a URL.

Books and E-Books MLA Bibliography Examples

For books, MLA reference list entries use the following format. Add the URL at the end for e-books.

Last Name, First Name Middle Name. Title . Publisher, Date. URL

Bibliography In Research Paper: Know Everything About It

Learn about what is a bibliography in a research paper and how to write a bibliography that makes your research paper undeniably perfect.

Imagine yourself as a research student and you have to submit a thesis for which you collected all the information and wrote your thesis but forgot to add a bibliography to it. Now your professor rejects your thesis for that one mistake. How would you feel? Wouldn’t it be disappointing? 

It indeed is disappointing but do you really think a bibliography is that important? In fact, have you ever wondered what a bibliography is? You must’ve seen it at the end of every book or article that you read but you wouldn’t have paid much attention to it. Read the article to know the importance of a bibliography in a research paper and how to write it according to the guidelines given. 

What is a Bibliography?

A bibliography is a list of sources or materials that you might have referred to while writing an article or a research paper. If the reader wants to explore more about the content apart from what you’ve written, they would refer to the sources that you’ve mentioned and a bibliography can be helpful. 

For example, if you’re reading a fiction novel about the culture of a European country in the 18th- century and you wish to learn more about it, what would you do? Here comes the importance of a bibliography. The author might have mentioned his research works – from where he collected information regarding European culture and he might’ve cited all those previous works in the form of a bibliography at the end of the book. This could help readers like you to explore more about the topic.

Bibliography vs References

Bibliography and references appear synonymous and thus, most of us try to use them interchangeably. But did you know this isn’t right? While both of them appear similar, there is this small difference that actually makes a lot of sense if you get to know it.

If we see the definition of reference, is the citation of all the works/sources that one used “ within the body of the paper”. This is the most important key difference. While references refer to the work that is present within the paper, a bibliography refers to the works which are “ not specifically referred to within the body of the paper” that is, it needn’t be necessary for a bibliography to have the exact sources on its body and you can cite a source even if you just used it to refer something regarding the topic.

Steps To Write A Bibliography In Research Paper

• The initial and foremost step to be followed before writing a bibliography is to make a note of all the books/sources/works you read when you’re doing your background research for a paper.
• Once you have a list of the books or sources, you need to check for the following information in the source :

If it is printed, check out for

• Authors’ name
• Title of publication
• Date of publication
• The publishing company of a book
• Page number(s)

If it is from a website, check out for

• Author and editor name
• Title of the webpage
• The company that posted that webpage
• URL of that webpage
• Before writing out your bibliography, you should know that there are two major guidelines for writing a bibliography (MLA Format and APA Format), and use them according to the need of your paper.
• Once you’re done writing a bibliography, make sure that you cited all the sources that you mentioned in the paper and whether you cited them in the correct format or not.
• If there are any mistakes or necessary changes, make them before you submit your paper.

Writing a bibliography might be a tiresome process as there’s a huge list of sources that need to be mentioned but adding a bibliography gives your research paper a more professional touch and sets your paper apart from the rest of the crowd.

What Is A Bibliography?

Bibliography Definition: Overview

A bibliography is a list of sources used in researching and writing a work, such as a book, article, or academic paper. It includes detailed information about each source, like the author's name, title, and publication date. Bibliographies serve to credit authors, avoid plagiarism, provide references for readers, and demonstrate the research scope. They can be annotated, which includes summaries or evaluations, or simply list the sources. Proper formatting depends on the required citation style, such as APA, MLA, or Chicago.

Simply put, a bibliography lists all the sources you’ve used while working on a paper. It’s a window where your readers can check and verify the validity of your claims, and to know the origins of your research. Academic papers aren’t the only works that have bibliographies. Websites, interviews, and articles can also have them. 

The definition of bibliography encompasses many of these resource lists. Adding an extensive and authentic bibliography to your work credits the original authors and enhances credibility and trustworthiness.

Purpose of A Bibliography

The purpose of a bibliography is to help you keep track of your research, assist readers in finding more information on the topic, prove that your information comes from trustworthy sources, and give credit to the original sources and authors.

A bibliography has many purposes. That’s why your academic paper must have one. It serves to help in many different things:

• Improves your work’s credibility : It backs up your information and makes it credible and trustworthy.
• Counters plagiarism : It helps give credit to your sources and their authors which helps uphold integrity and counters plagiarism.
• Serves as guidance : By demonstrating your sources, your bibliography helps your readers the ability to explore your topic further and gain a deeper understanding of it.

Types of Bibliographies

Now we’ve gone over the basics of what’s a bibliography, let’s explore the different types. There are several types of them, each having a different purpose:

• Descriptive bibliographies : These provide very detailed information about the sources. They provide information on physical attributes, printing history, format, and edition.
• Enumerative bibliographies : These are not as detailed. They are organized either chronologically, alphabetically, or chronologically.
• Analytical bibliographies : These types examine the sources’ history, context, and production. They offer a deeper analytical view of the sources.

Annotated Bibliographies

A hard entry is the annotated bibliography. Here’s a more extensive guide on how to write an annotated bibliography for your convenience. These go beyond just listing sources. You typically include summaries and evaluations of your source entries with this type.

By doing so, you help your readers grasp the importance of each source and how it contributes to your work. When you properly create an annotated bibliography, you showcase your critical thinking capabilities. This, in turn, can enhance your paper’s overall credibility, and it also helps your readers in their further research.

We’ve explored the many aspects of what is a bibliography and answered the main questions. So, in the spirit of better understanding, let’s also learn about footnotes. 

Footnotes give additional information or citations at the bottom of a page. Footnotes are used to give credit or to highlight your sources without disrupting the flow of your main work. They can also be used to provide additional details that support your writing.

Footnotes can provide context and explanations and can highlight references. This, in turn, guides your readers and helps them fully understand your message. 

Common Mistakes When Creating Your Bibliography

There are many avoidable pitfalls you can counter just by reading our guides, but if you’re tired and need an extra hand, you can always send in a request for help with your bibliography or even a request to ‘ Write my book report .’ We’ll be on that task ASAP. If you’re feeling fit to learn more, here are some crucial pointers to remember:

• Incomplete citations : Be sure to finish your citations by providing all the necessary information like author, title, publication date, and publisher. 
• Bad formatting : Be consistent and stick to one citation style for your bibliography.
• Missing sources : Make sure all the sources you reference in your work are in your bibliography.
• Wrong order : Make sure you’ve organized your entries accordingly.

Formatting and Style

We’ve tackled all the definitions and the bibliography meaning. Now, let’s take a look at the crucial elements of formatting and style. Here’s what to remember:

• APA (American Psychological Association) : This style is commonly used in the social sciences. It highlights the author and publication year in in-text citations.
• MLA (Modern Language Association) : Very widely used in literature and language studies. It highlights the author and page number for in-text citations.
• Chicago/Turabian : This style is used in many different disciplines since it’s considered versatile. This style has two systems. One is the notes and bibliography style, used widely in the humanities. The other one is the author-date system, which is used in the sciences. Turabian is a simplified version of Chicago and is used by students.
• Harvard : This one uses author-date in-text citations and uses a reference list. It’s used in many different fields and is quite popular in Australia and the UK.

Key Takeaways

“What is a bibliography?” Now we know. Let’s remember some of the key points we’ve encountered in this guide for future reference:

• Different types : descriptive, enumerative, analytical.
• Avoiding common pitfalls : complete citations, be consistent, organize and include all sources.
• Choose one style : Choose MLA, APA, Chicago/Turabian or Harvard and stick to one style for your whole bibliography.

Write an Annotated Bibliography

What is an annotated bibliography?

It is a list of citations for various books, articles, and other sources on a topic. 

An annotation is a short summary and/or critical evaluation of a source.

Annotated bibliographies answer the question: "What would be the most relevant, most useful, or most up-to-date sources for this topic?"

 Annotated bibliographies can be part of a larger research project, or can be a stand-alone report in itself. 

Annotation versus abstracts 

An abstract is a paragraph at the beginning of the paper that discusses the main point of the original work. They typically do not include evaluation comments. 

Annotations can either be descriptive or evaluative. The annotated bibliography looks like a works cited page but includes an annotation after each source cited. 

Types of Annotations: 

Descriptive Annotations: Focuses on description. Describes the source by answering the following questions. 

Who wrote the document?

What does the document discuss?

When and where was the document written? 

Why was the document produced?

How was it provided to the public?

Evaluative Annotations: Focuses on description and evaluation. Includes a summary and critically assess the work for accuracy, relevance, and quality. 

Evaluative annotations help you learn about your topic, develop a thesis statement, decide if a specific source will be useful for your assignment, and determine if there is enough valid information available to complete your project.

What does the annotation include?

Depending on your assignment and style guide, annotations may include some or all of the following information. 

• Should be no more than 150 words or 4 to 6 sentences long. 
• What is the main focus or purpose of the work?
• Who is the intended audience?
• ​How useful or relevant was the article to your topic?
• Was there any unique features that useful to you?
• What is the background and credibility of the author?
• What are any conclusions or observations that your reached about the article?

Which citation style to use?

There are many styles manuals with specific instructions on how to format your annotated bibliography. This largely depends on what your instructor prefers or your subject discipline. Check out our citation guides for more information. 

Additional Information

Why doesn't APA have an official APA-approved format for annotated bibliographies?

Always consult your instructor about the format of an annotated bibliography for your class assignments. These guides provide you with examples of various styles for annotated bibliographies and they may not be in the format required by your instructor. 

Citation Examples and Annotations

Book Citation with Descriptive Annotation

Liroff, R. A., & G. G. Davis. (1981). Protecting open space: Land use control in the Adirondack Park. Cambridge, MA: Ballinger.

This book describes the implementation of regional planning and land use regulation in the Adirondack Park in upstate New York. The authors provide program evaluations of the Adirondack Park Agency’s regulatory and local planning assistance programs.

Journal Article Citation with Evaluative Annotation

Gottlieb, P. D. (1995). The “golden egg” as a natural resource: Toward a normative theory of growth management. Society and Natural Resources, 8, (5): 49-56.

This article explains the dilemma faced by North American suburbs, which demand both preservation of local amenities (to protect quality of life) and physical development (to expand the tax base). Growth management has been proposed as a policy solution to this dilemma. An analogy is made between this approach and resource economics. The author concludes that the growth management debate raises legitimate issues of sustainability and efficiency.

Book Citation

Lee, Seok-hoon, Yong-pil Kim, Nigel Hemmington, and Deok-kyun Yun. “Competitive Service Quality Improvement (CSQI): A Case Study in the Fast-Food Industry.” Food Service Technology 4 (2004): 75-84.

In this highly technical paper, three industrial engineering professors in Korea and one services management professor in the UK discuss the mathematical limitations of the popular SERVQUAL scales. Significantly, they also aim to measure service quality in the fast-food industry, a neglected area of study. Unfortunately, the paper’s sophisticated analytical methods make it inaccessible to all but the most expert of researchers.

Battle, Ken. “Child Poverty: The Evolution and Impact of Child Benefits.”  A Question of Commitment: Children's Rights in Canada . Ed. Katherine Covell and R.Brian Howe. Waterloo, ON: Wilfrid Laurier University Press. 2007. 21-44.

             Ken Battle draws on a close study of government documents, as well as his own research as an extensively-published policy analyst, to explain Canadian child benefit programs.  He outlines some fundamental assumptions supporting the belief that all society members should contribute to the upbringing of children.  His comparison of child poverty rates in a number of countries is a useful wake-up to anyone assuming Canadian society is doing a good job of protecting children.  Battle pays particular attention to the National Child Benefit (NCB), arguing that it did not deserve to be criticized by politicians and journalists.  He outlines the NCB’s development, costs, and benefits, and laments that the Conservative government scaled it back in favour of the inferior Universal Child Care Benefit (UCCB).  However, he relies too heavily on his own work; he is the sole or primary author of almost half the sources in his bibliography.  He could make this work stronger by drawing from others' perspectives and analyses.  However, Battle does offer a valuable source for this essay, because the chapter provides a concise overview of government-funded assistance currently available to parents.  This offers context for analyzing the scope and financial reality of child poverty in Canada.

Journal Article Example

  Kerr, Don and Roderic Beaujot. “Child Poverty and Family Structure in Canada, 1981-1997.”  Journal of Comparative Family Studies  34.3 (2003): 321-335.

             Sociology professors Kerr and Beaujot analyze the demographics of impoverished families.  Drawing on data from Canada’s annual Survey of Consumer Finances, the authors consider whether each family had one or two parents, the age of single parents, and the number of children in each household.  They analyze child poverty rates in light of both these demographic factors and larger economic issues.  Kerr and Beaujot use this data to argue that.

How To Cite Sources: In-depth Guide

Did you know that, on average, college students spend over 12 hours a week researching and writing essays? It's a considerable investment of time and energy, and the quality of your work can greatly impact your academic success. One of the critical aspects of crafting top-notch essays is the art of citing sources correctly. Whether you're in the world of psychology (APA), humanities (MLA), or history (Chicago), understanding and navigating the citation styles relevant to your field is a must.

In this comprehensive article, our college essay writing service will delve deep into the world of academic writing and the crucial role that proper source citation plays in your success. Explore the intricacies of citing sources in APA, MLA, and Chicago styles as we provide detailed guidance, real-world citing sources examples, and practical insights. Discover the nuances of citing multiple sources in one sentence, using citation generators, and citing primary sources. Additionally, we'll conduct a comparative analysis of these citation styles to help you choose the right one for your research papers. By the end of this journey, you'll be well-versed in the art of source citation and ready to elevate your academic writing to the next level.

When to Source Sources in Academic Writing?

In the realm of academic writing, citing sources accurately is far more than a mere formality; it's an ethical responsibility and a testament to the integrity of your work. Proper source citation serves as the foundation of scholarly discourse, ensuring transparency, credibility, and respect for intellectual property. By crediting the authors and researchers who've paved the way, you acknowledge the collective knowledge of your field.

Interestingly, a study by the International Journal of Educational Integrity found that improper citation practices are a leading cause of plagiarism, a serious offense in academia. In fact, plagiarism-detection software like Turnitin is now widely used to uphold academic integrity. This is where the convenience of citing sources generators becomes apparent, helping students and researchers ensure proper attribution while streamlining the citation process, whether they're citing sources in Chicago style or other formats.

Moreover, accurate citations, including a parenthetical citation, allow readers to trace your sources, verify your claims, and engage in meaningful discussions. They act as a bridge between your work and the wealth of research that precedes it. In essence, mastering the art of source citation is not just about compliance with formatting rules; it's about participating in a respectful and dynamic conversation within your academic community while giving due credit to the sources, particularly when citing primary sources, that have contributed to the intellectual growth of your field.

Let us handle the 'quote' business for you!

APA Citation Style Basics

American Psychological Association (APA) style is a widely used and meticulously structured citation format primarily designed for disciplines in the social sciences. Understanding the fundamentals of APA format citing sources is vital for any student or researcher in psychology, sociology, education, and related fields. Here are some key insights into the world of APA citations from our ‘ do my paper ’ experts:

• In-text Citations with Precision : In APA style, in-text citations are concise and informative. For instance, consider this sentence: 'The impact of climate change on coastal ecosystems is a growing concern (Johnson, 2018).' In this case, 'Johnson' is the author's last name, and '2018' is the publication year. This format allows readers to quickly identify and locate the source in the reference list (Johnson, 2018).
• The Role of the Reference List : The reference list in APA style is like the treasure trove of your sources. It's a comprehensive list of all the materials you've cited in your work. For example, a reference entry for a journal article would look like this: Johnson, S. (2018). Climate Change Effects on Coastal Biodiversity . Environmental Studies, 36 (3), 255-269.
• DOI and Electronic Sources : In the digital age, many sources are found online, which is why APA has introduced the Digital Object Identifier (DOI) system. For instance, an APA citation for an online journal article with a DOI might look like this: Smith, P. (2021). Renewable Energy Solutions for Sustainable Future . Environmental Science Review, 45 (2), 101-120. https://doi.org/10.12345/esr.2021.2.101
• Citing Multiple Sources in One Sentence APA : APA rules for citing multiple sources in a single sentence are clear and practical. Consider this example for citing two sources in one sentence APA: 'Several studies (Smith, 2021; Johnson, 2018) have highlighted the urgency of addressing climate change's impact on coastal ecosystems.' Here, both sources are listed chronologically, creating a seamless flow of information in your text.
• The Power of Consistency : Consistency is a cornerstone of APA style. From the formatting of headings (e.g., Level 1, Level 2) to the use of italics for titles and the ordering of elements in a reference entry, adhering to the APA guidelines ensures your work looks polished and professional.
• Evolving Rules : As research methods and publishing practices evolve, so do citation styles. It's essential to stay updated with the latest APA publication manual as they adapt to the changing landscape of academic communication (American Psychological Association, 2020).

MLA Citation Style Basics

The Modern Language Association (MLA) citation style is the hallmark of academic writing in the humanities, literature, and related fields. It's known for its simplicity, elegance, and focus on clarity. Here's a concise guide from our argumentative essay writing service to help you navigate the intricacies of MLA format citing sources:

• In-text Citations with Author-Page Format : Citing sources MLA style primarily uses a simple author-page format for in-text citations. For example, 'In his renowned work, Shakespeare explores themes of love and fate (Smith 45).' Here, 'Smith' is the author's last name, and '45' is the page number. This format allows readers to locate the corresponding entry in the Works Cited page.
• The Works Cited Page : The Works Cited page is the heart of MLA citation. It's a detailed list of all the sources you've referenced in your paper. Each entry follows a specific format, including the author's name, source title, publication information, and more.
• Citing Digital and Print Sources : MLA is adaptable to both digital and print sources. For a print book, an MLA citation would look like this: Smith, John. The Art of Writing . Random House, 2020. For an online article, you might format it as follows: Johnson, Sarah. 'The Digital Literary Landscape.' Digital Humanities Review , vol. 28, no. 3, 2021, www.example.com/dhr/28-3/johnson.
• Citing Multiple Works by the Same Author : When citing multiple works by the same author, use a shortened version of the title to differentiate them. For instance, (Smith, Art of Writing 34) and (Smith, 'Literary Exploration' 18).
• The Importance of Punctuation and Formatting : Proper punctuation and formatting are essential in MLA citation. Pay attention to italics for titles, quotation marks for short works, and the correct use of commas, periods, and colons.
• Evolving Guidelines : MLA citing sources guidelines are known for evolving with technology and research methods. Staying up-to-date with the latest MLA handbook is crucial to ensure your citations align with current standards.

Chicago Citation Style Basics

The Chicago citation style, often used in history, arts, and social sciences, is a versatile and comprehensive system known for its flexibility and depth. Here's a guide to help you embrace the intricacies of Chicago citation:

• Two Distinct Documentation Systems : Chicago offers two documentation systems: the Notes and Bibliography system (commonly used in history and the humanities) and the Author-Date system (preferred in the social sciences). Understanding which system your discipline employs is crucial.
• Footnotes and Endnotes : In the Notes and Bibliography system, footnotes or endnotes are used to cite sources within the text. For example, 'The Industrial Revolution transformed society in profound ways. [1]' The corresponding note at the bottom of the page or end of the chapter provides full citation details.
• Bibliography or Reference List : In Chicago, both systems require a comprehensive bibliography at the end of your work, which lists all the sources you've cited. Each entry should include elements like the author's name, title, publisher, and publication date.
• Citing primary sources Chicago style : Chicago is particularly celebrated for its approach to citing primary sources, such as archival documents, letters, and manuscripts. It demands specific details about the source's origin, location, and access date, ensuring a comprehensive record.
• Citing Multiple Sources in One Footnote Chicago : When citing multiple sources in one footnote, list them in chronological order, separated by semicolons. For example, 'The 19th century saw significant advancements in technology and communication.[1];[2].'
• The Emphasis on Publication Details : Chicago places a strong emphasis on providing extensive publication information for each source cited. This includes details like the place of publication and specific page numbers in the case of print sources.
• Evolving Standards : Just like other citation styles, Chicago's guidelines evolve over time to accommodate changes in research practices. Staying informed about the latest Chicago Manual of Style editions is essential for accurate citations.

APA vs. MLA vs. Chicago: Key Similarities and Differences

Citation styles play a pivotal role in academic writing, helping maintain consistency, credibility, and clarity in scholarly work. Among the most widely used styles are APA (American Psychological Association), MLA (Modern Language Association), and Chicago. Let's explore the key similarities and differences between these three major citation styles.

Similarities:

• In-text Citations : All three styles use in-text citations to acknowledge the sources of information. In-text citations allow readers to identify the corresponding entry in the reference list or bibliography.
• Reference Lists or Bibliographies : APA, MLA, and Chicago all require a list of references, works cited, or a bibliography at the end of the document. These lists provide complete details about the sources cited in the text.
• Author and Publication Year : Both APA and MLA styles include the author's last name and the publication year within in-text citations. This allows readers to easily locate the source in the reference list.
• Digital Object Identifiers (DOIs) : APA and MLA provide guidelines for citing sources with DOIs, ensuring the accuracy and stability of online references.

Differences:

Disciplines and Focus:

• APA is primarily used in the social sciences, including psychology, sociology, and education, with a focus on empirical research and concise, structured writing.
• MLA is widely employed in humanities disciplines, such as literature and language studies, emphasizing the analysis of literary and cultural texts.
• Citing sources Chicago style is versatile, used in history, arts, and social sciences, offering both Notes and Bibliography and Author-Date systems to accommodate different research needs.

In-text Citation Styles:

• APA uses an author-date format, e.g., (Smith, 2020), for in-text citations.
• MLA uses an author-page format, e.g., (Smith 45), for in-text citations.
• Chicago uses footnotes or endnotes, which provide full citations in superscript numbers within the text and often a bibliographic entry at the bottom of the page or the end of a chapter.

Reference List/Bibliography Format:

• APA organizes the reference list alphabetically by the author's last name, followed by the publication date.
• MLA arranges the works cited list alphabetically by the author's last name and, if there is no author, by the title.
• Chicago's Notes and Bibliography system uses footnotes or endnotes for citations and a bibliography, while the Author-Date system includes an alphabetically-arranged reference list.

Handling Multiple Sources in One Citation:

• APA typically lists multiple sources in one in-text citation using semicolons, e.g., (Smith, 2020; Johnson, 2019).
• MLA uses commas to separate multiple sources within one in-text citation, e.g., (Smith 45, Johnson 22).
• Chicago usually utilizes footnotes or endnotes to cite multiple sources, each source marked with a superscript number in the text.

Citing Page Numbers:

• In APA and MLA, page numbers are often included in in-text citations for direct quotations, e.g., (Smith, 2020, p. 25) or (Smith 25).
• Chicago uses footnotes or endnotes to include page numbers for direct quotations within the text itself.

Final Thoughts

In conclusion, mastering the nuances of APA, MLA, and Chicago citation styles, including the specific requirements for citing primary sources, is an invaluable skill for academic success. It will also be a helpful guide as you explore how to write a college admission essay . These styles empower you to engage in scholarly conversation while maintaining the integrity of your research. Choose the one that best aligns with your field and project, and remember that accurate citation not only upholds academic standards but also showcases your commitment to excellence in your work.

MLA Works Cited Page: Format, Template & Examples

The Works Cited page is a part of research papers written in the Modern Language Association (MLA) format where all sources used by the author are listed. While writing research papers, authors may consult several sources and use their data or paraphrase parts of the original text. It is essential to give due credit to the used sources and cite them appropriately to avoid plagiarism. This list of sources offers an easy reference for readers who may want to refer to the original source for their own research.  

A well-formatted and accurate Works Cited page can provide readers with specific details to help them access that source. For example, for a journal article, in addition to basic details like author name, title, journal name, etc., the MLA Works Cited page also provides the volume and issue numbers, page numbers, publisher, etc. A Works Cited page gives credibility to the research paper, proving that the information published is accurate and backed by evidence. 

This article describes the template of an MLA Works Cited page along with examples and suggests steps to ensure accurate formatting of all entries.

What is a Works Cited Page?

The MLA Works Cited page 1 lists all the sources used while writing research papers. This page is always the last one after the main content. A Works Cited page uses the official MLA format and has similar content as reference lists used by other styles such as the Chicago Manual of Style (Chicago style), the American Psychological Association (APA), and the American Medical Association (AMA). Each style uses a different format, emphasizing different elements. 

The Works Cited page helps avoid plagiarism by crediting the sources and allows readers to quickly locate the sources. Papers in MLA format should always have a Works Cited page and each entry on this page should be cited in the text at the corresponding location. 

Basic Rules for an MLA Works Cited Page

Here are some basic rules for writing the MLA Works Cited page: 2  

• Start your Works Cited list on a fresh page at the end of your paper, with the same formatting as other sections, such as one-inch margins, last name, page number, and header. 
• Align the title, “Works Cited,” at the top center. Don’t use italicization, boldfacing, quotation marks, or all-caps to highlight the title. 
• Left align the citations and arrange them alphabetically by authors’ last names. If author names are unavailable, arrange by the first letter in the title (other than A, An, or The). 
• Do not use serial numbering or bullets to list the entries. 
• Double space all citations. 
• Indent the second and subsequent lines of citations by 0.5 inches to create a hanging indent (Figure 1). 

• List page numbers of the sources correctly. If only one page of a print source is used, use the abbreviation “p.” before the page number (e.g., p. 232). If a page range is used, use “pp.” (e.g., pp. 232-38). 
• For online sources, include a location, like a URL or a digital object identifier (DOI). Delete “http://” from URLs. The DOI or URL is usually the last element in a citation. 
• End all entries with a period. 

Citing Sources in MLA

A citation in an MLA Works Cited page requires the following core elements. These elements should be written in the order given below, followed by the punctuation mark shown unless the particular element is the final element of the entry, in which case, it should end with a period. 4,5  

• Author’s name
• Title of source
• Title of the container, (a container is the larger publication in which the text is published. For example, if citing an article from a journal, the journal is the container) 
• Other editors, translators, contributors
• Publication date
• Location (page numbers in print versions; DOI or URL in online versions) 

A few optional elements can be included, if available: 

• Date of access (the date you last accessed the online source) 
• Date of original publication 
• Format of media source 

All style guides have their own specific formats for writing different sources in a reference list—journal articles, printed and digital books, videos, websites, etc. The MLA-style format for different types of sources is listed below: 4

Format of an MLA Works Cited Page

Here’s a list of steps for formatting the MLA Works Cited page:

• Place one-inch margins around the entire document except for the “running head.” In the page setup settings, you can view and modify the margin size. 
• Double space the entire page using the “Line spacing” or “Paragraph spacing” options in your word processing program. 
• Organize the Works Cited entries in either alphabetical (by author name or title) or non-alphabetical order. 1,2

Example: 

Benjamin, Chloe. The Immortalists . Penguin, 2018. 

Black Panther . Directed by Ryan Coogler, performance by Chadwick Boseman, Marvel Studios, 2018. 

Egan, Jennifer. Manhattan Beach . Scribner, 2017. 

Formatting Headings and Citation Titles on an MLA Works Cited Page

The following points outline the basic format for headings and titles used on a Works Cited page. 1 The running head is at the top right corner of every page of the document. It displays the last name of the author and the page number (e.g., Letterman 6). 

• The running head should be placed half an inch from the top of the page and along the right side’s one-inch margin. 
• The page title (Work/Works Cited) should be written below the running head.  
• No center alignment 
• No boldfacing, italicization, or underlining 
• Same font size (12 point) and type as the entire document 
• Separated by a double space from the first citation on the page 

Consider the following rules while formatting source titles: 1,5,7,8  

• List the full title as the original source and use title case (capitalize all principal words, except articles [a, an, the], prepositions, or coordinating conjunctions [and, for, but, or, so, nor, yet] when in the middle of the title). 

Examples:  

The Code of the Exiled, Wizard of Oz, Harry Potter and the Goblet of Fire  

Cheyfitz, Eric. The Poetics of Imperialism: Translation and Colonization from The Tempest to Tarzan. Expanded ed., U of Pennsylvania P, 1997. 

• Separate the subtitle from the title with a colon and space. 

Goldman, Anne. “Questions of Transport: Reading Primo Levi Reading Dante.” The Georgia Review , vol. 64, no. 1, 2010, pp. 69-88. 

• Italicize titles if the source is self-contained and independent, e.g., titles of books, plays, films, periodicals, journals, magazines, databases, and websites. 

Example: Salinger, J. D. The Catcher in the Rye . Little Brown, 1991. 

• Enclose titles in quotation marks if the source is part of a larger work, e.g., articles, essays, chapters, poems, short stories, webpages, songs, television episodes, and speeches. 
• Titles beginning with numbers are placed in the reference list as if the title was written out alphabetically. 

Formatting Author Names on an MLA Work Cited Page

Few important rules to consider when formatting author names: 1,2  

Single author

• List author names alphabetically by the author’s last name (or, for entire edited collections, editor names). The format for writing author names is as follows: 

Last name, first name, middle name or middle initial  

Said, Edward W. Culture and Imperialism . Knopf, 1994. 

• To cite more than one work by the same author, order the entries alphabetically by title, and use three hyphens in place of the author’s name for every entry after the first. 

Alcott, Louisa May. “Eight Cousins.” Project Gutenberg , 2018, www.gutenberg.org/files/2726/2726-h/2726-h.htm . 

—. Little Women . Bantam Classics, 1983. 

—. Rose in Bloom . CreateSpace, 2018. 

Two authors

The first listed author’s name on the source is the first author in the reference.  

Last name, First name of author 1, and First name Last name of author 2 

Pavear, Richard, and Larissa Volokhonsky, translators. Crime and Punishment . By Feodor Dostoevsky, Vintage eBooks, 1993. 

Three or more authors

Include only the first listed author’s last name, followed by a comma and their first name, followed by another comma and then “et al.”  

Example:  

Baron, Sabrina Alcorn, et al., editors. Agent of Change: Print Culture Studies after Elizabeth L. Eisenstein. U of Massachusetts P / Center for the Book, Library of Congress, 2007. 

General rules

• Do not list titles (Dr., Sir, etc.) or degrees (PhD, MA, MD, etc.) with names but include suffixes like “Jr.” or “II.”  

King, Martin Luther, Jr. 

• Alphabetize works with no known author by their title; use a shortened version of the title in the parenthetical citations in your paper. 

Baudrillard, Jean. Simulacra and Simulations . […] 

Boring Postcards USA […] 

• To cite works by authors using a pseudonym or stage-name, cite the better-known name if the person is well known. For example, Lewis Carroll is the pseudonym of Charles Dodgson, and is the better-known name so only the pseudonym should be used. If the pseudonym is less well known, cite the real name in square brackets after the pseudonym.  

Van Dyne, Edith [L. Frank Baum]. Aunt Jane’s Nieces At Work . 1st World Library, 2006. 

Key Takeaways

To summarize, an MLA Works Cited page should have the following format: 

• Starts on a new page at the end. 
• Centered page title without any highlights. 
• Double-spaced citations, preferably in Times New Roman 12-pt font. 
• Left-justified entries with a hanging indent of 0.5 inches. 
• Source titles in title case. 
• Entries ordered by the first word, typically author name or the first word in the title (except articles a, an, the). If the title begins with a year or a number, alphabetize it as if the number/year is spelled out. 

Frequently Asked Questions

A1. The Works Cited page and references have a similar purpose; both include sources that have been specifically cited or paraphrased in the paper and whose data have been directly used. A bibliography includes a list of sources related to the content in a research paper, that is, sources that you may have consulted while writing your research paper, but may not have actually used, cited, or paraphrased from. 1   

A2. Yes, there are a few other styles for citing references, such as the Chicago Style, AMA Manual of Style, APA Manual of Style, and the IEEE style. All of these have different referencing formats. In addition, organizations may create their own referencing styles, commonly called a house style. 

A3. No, the Works Cited page should include only those sources that you have cited or whose data you have used in your research paper. Sources that you have only consulted while conducting research should be included in a bibliography. 

A4. Per MLA format, ignore symbols, such as hashtags when alphabetizing. Use the first letter in the entry to alphabetize. 9   Example:  @AP. “It’s been four years since the #MeToo movement took over social media. . . .” X, 15 Oct. 2021, https://twitter.com/AP/status/1449019990741590025.  “#MeToo Poll: Many in US More Willing to Call Out Misconduct.” Associated Press , 15 Oct. 2021, https://apnews.com/article/sexual-misconduct-metoo-79688da3a0c3519d2a76b5b6e6b23ba7.  “#MeToo Protest in Amsterdam after Allegations at TV Show.” Associated Press , 29 Jan. 2022, https://apnews.com/article/entertainment-business-arts-and-entertainment-netherlands-amsterdam-4bb589aae061e534b1a47ac453e9d85f . 

A5. Here is one way of adding a hanging indent in MS Word: 10   1. Highlight the text that you want to format.   2. Click the Home tab at the top of the page; in the “Paragraph” section click the small arrow in the lower-right corner to open a window with different paragraph setting options.   3. In that settings window, look for a section, “Indentation,” which has an option, “Special.” Click the drop-down menu beneath Special and select Hanging.   4. MS Word will mostly have the default spacing of the hanging indent set to 0.5 inches. To adjust the spacing, change the number in the By section.  5. Click OK to save and apply the hanging indent to your highlighted text. 

To summarize, an MLA Works Cited page is an essential part of a manuscript written using the MLA style and includes all sources used by the author to write the research paper. As described in the article, the Works Cited page and its entries have a specific format that should be strictly followed, and all the core elements included in the individual entries.  

We hope this article has provided a deeper understanding of the MLA style and will help you apply this format to all your Works Cited pages.

Will I Get Caught Using Chat GPT?

ChatGPT has been around for a little over a year but already found popularity among all groups of users. School and college students have taken a particular liking to it. However, many students avoid using the chatbot for fear that their teacher might catch them.

Read this article to learn more about ChatGPT, its features, and whether your teacher can actually find out if you use it for your homework.

What is Chat GPT?

ChatGPT was first introduced to the world in November 2022. At the time, it was a one-of-a-kind chatbot that used the power of generative AI to create content in response to specific prompts. In simpler words, ChatGPT can analyze your questions and use its vast database of texts to write a cohesive reply.

Before it was introduced to the public, the AI was trained on a massive amount of text sources. Slowly but surely, it “learned” how language works. Now, it can “speak” using this knowledge, repeating the patterns it learned and predicting how the next part of its response should go word by word.

This technology revolutionized the whole globe and opened a new world of opportunities to users from different backgrounds.

Chat GPT: Applications and main features

As a text-based model, ChatGPT can be used across many domains. Let’s explore the main capabilities of Chat GPT and its applications in real life.

• Content creation . ChatGPT can create completely new texts based on a user’s prompt. This is a particularly useful feature for businesses that have to generate a lot of content like ad texts, social media, blog posts, video scripts, etc.
• Research . ChatGPT can use its enormous database to find answers to specific research questions or provide brief overviews of certain sources. It can also give a list of references that researchers are welcome to study further for a more in-depth analysis.
• Translation . ChatGPT can translate texts into over 50 different languages. It can also provide feedback and proofread existing translations.
• Consulting . It’s possible to use ChatGPT for various consultations. Most users prefer asking their questions to the chatbot instead of sorting through myriad web pages selected by search engines. Also, Chat GPT helps users brainstorm ideas, acts as customer support, and even gives basic mental health counseling.
• Proofreading . You can ask the AI chatbot to check your texts or translations for any grammar mistakes. It can in turn give you suggestions to improve your text even more.

As you can see, the capabilities of Chat GPT extend to a wide range of areas, and this is just a small portion of what it can do. It’s also safe to say that the true potential of GPT technology is yet to be explored.

Can I get caught using ChatGPT?

Given how quickly OpenAI’s chatbot took over the world, it’s not surprising that students have already discovered all the benefits of using generative AI for homework. However, there is a common concern that AI writing can be detected by teachers and professors. So, is it true?

Unfortunately, the answer is yes. Texts produced by ChatGPT have several distinct features of texts that experienced educators can easily detect. Besides, there already are a lot of automatic services that can analyze your essays and find traces of ChatGPT origin. Here is a list of these features that are often attributed to AI generators.

• Repetitive patterns . While ChatGPT was trained on a large dataset of texts, it can still use repetitive phrases, particularly in specific contexts. This repetition can become very obvious in longer texts like essays.
• Unusual phrasing . AI may generate sentences or phrases that sound slightly off or unnatural to human readers, which can be caused by low-quality training data or errors in the way the model understands the language.
• Lack of emotion . ChatGPT-generated text often lacks the emotional depth that is typical of human writing. No matter how hard we try to stay neutral, our personal biases seep into our writing while AI tends to produce unnaturally dry text. 
• Factual errors . There are a lot of examples when ChatGPT was seen making up non-existent facts. This is the most obvious mistake that can tip your teacher off about your use of AI generators.
• Lack of creativity . AI may produce texts that rely on common language idioms or templates. This can become a hindrance, especially when your assignment is to show off your creative skills.

As you see, detecting ChatGPT can be easy if you know what to look for. That’s why teachers can often tell when you use it to complete your assignments.

How to avoid getting caught using Chat GPT

Thankfully, there are ways to hide that you used Chat GPT help. But they still require some effort on your part.

1. Generate ideas instead of text

Sure, It’s easier to ask ChatGPT to write an entire paper at once. But it’s much safer to use it to brainstorm ideas. Ask it to compile a plan for your essay or think of supporting arguments. Don’t copy everything it writes without editing. Remember that you need to stick to your style of writing.

Search for sources

You can also ask ChatGPT to compile a list of sources for your papers. But always double-check that these sources exist. As we already know, ChatGPT can write factually incorrect texts, so it’s better to study sources yourself. This way, you’ll also be ready should your teacher ask any follow-up questions about your research.

Use Ai-generator Aithor

Background Plans to phase out fossil fuel-powered internal combustion engine (ICE) vehicles and to replace these with electric and hybrid-electric (E-HE) vehicles represent a historic step to reduce air pollution and address the climate emergency. However, there are concerns that E-HE cars are more hazardous to pedestrians, due to being quieter. We investigated and compared injury risks to pedestrians from E-HE and ICE cars in urban and rural environments.

Methods We conducted a cross-sectional study of pedestrians injured by cars or taxis in Great Britain. We estimated casualty rates per 100 million miles of travel by E-HE and ICE vehicles. Numerators (pedestrians) were extracted from STATS19 datasets. Denominators (car travel) were estimated by multiplying average annual mileage (using National Travel Survey datasets) by numbers of vehicles. We used Poisson regression to investigate modifying effects of environments where collisions occurred.

Results During 2013–2017, casualty rates per 100 million miles were 5.16 (95% CI 4.92 to 5.42) for E-HE vehicles and 2.40 (95%CI 2.38 to 2.41) for ICE vehicles, indicating that collisions were twice as likely (RR 2.15; 95% CI 2.05 to 2.26) with E-HE vehicles. Poisson regression found no evidence that E-HE vehicles were more dangerous in rural environments (RR 0.91; 95% CI 0.74 to 1.11); but strong evidence that E-HE vehicles were three times more dangerous than ICE vehicles in urban environments (RR 2.97; 95% CI 2.41 to 3.7). Sensitivity analyses of missing data support main findings.

Conclusion E-HE cars pose greater risk to pedestrians than ICE cars in urban environments. This risk must be mitigated as governments phase out petrol and diesel cars.

WHAT IS ALREADY KNOWN ON THIS TOPIC

Electric cars are quieter than cars with petrol or diesel engines and may pose a greater risk to pedestrians.

The US National Highway Transportation Safety Agency found that during 2000–2007 the odds of an electric or hybrid-electric car causing a pedestrian injury were 35% greater than a car with a petrol or diesel engine.

The UK Transport Research Laboratory found the pedestrian casualty rate per 10 000 registered electric or hybrid-electric vehicles during 2005–2007 in Great Britain was lower than the rate for petrol or diesel vehicles.

WHAT THIS STUDY ADDS

In Great Britain during 2013–2017, pedestrians were twice as likely to be hit by an electric or hybrid-electric car than by a petrol or diesel car; the risks were higher in urban areas.

HOW THIS STUDY MIGHT AFFECT RESEARCH, PRACTICE OR POLICY

The greater risk to pedestrian safety posed by electric or hybrid-electric cars needs to be mitigated as governments proceed to phase out petrol and diesel cars.

Drivers of electric or hybrid-electric cars must be cautious of pedestrians who may not hear them approaching and may step into the road thinking it is safe to do so, particularly in towns and cities.

Introduction

Many governments have set targets to reach net-zero emissions to help mitigate the harms of climate change. Short-term health benefits of reduced emissions are expected from better air quality with longer-term benefits from reduced global temperatures. 1

Transition to electric and hybrid-electric (E-HE) cars

One such target is to phase out sales of new fossil fuel-powered internal combustion engine (ICE) vehicles and replace these with E-HE vehicles. 2 3

Pedestrian safety

Road traffic injuries are the leading cause of death for children and young adults. 4 A quarter of all road traffic deaths are of pedestrians. 5 Concerns have been raised that E-HE cars may be more hazardous to pedestrians than ICE cars, due to being quieter. 6 7 It has been hypothesised that E-HE cars pose a greater risk of injury to pedestrians in urban areas where background ambient noise levels are higher. 8 However, there has been relatively little empirical research on possible impacts of E-HE cars on pedestrian road safety. A study commissioned for the US National Highway Transportation Safety Agency based on data from 16 States found that the odds of an E-HE vehicle causing a pedestrian injury were 35% greater than an ICE vehicle. 9 In contrast, a study commissioned by the UK Department for Transport found pedestrian casualty rates from collisions with E-HE vehicles during 2005–2007 were lower than for ICE vehicles. 10 Possible reasons for these conflicting results are that the two studies used different designs and estimated different measures of relative risk—the first used a case–control design and estimated an OR, whereas the second used a cross-sectional study and estimated a rate ratio. ORs will often differ from rate ratios. 11 Other reasons include differences between the USA and the UK in the amount and quality of walking infrastructure. 12

Aim and objectives

We aimed to add to the evidence base on whether E-HE cars pose a greater injury risk to pedestrians than ICE cars by analysing road traffic injury data and travel survey data in Great Britain.

We sought to improve on the previous UK study by using distance travelled instead of number of registered vehicles as the measure of exposure in estimation of collision rates.

The objectives of this study were:

To estimate pedestrian casualty rates for E-HE and ICE vehicles and to compare these by calculating a rate ratio;

To assess whether or not the evidence supports the hypothesis that casualty rate ratios vary according to urban or rural environments. 8

Study design

This study was an analysis of differences in casualty rates of pedestrians per 100 million miles of E-HE car travel and rates per 100 million miles of ICE car travel.

This study was set in Great Britain between 2013 and 2017.

Participants

The study participants were all pedestrians reported to have been injured in a collision with a car or a taxi.

The exposure was the type of propulsion of the colliding vehicle, E-HE or ICE. E-HE vehicles were treated as a single powertrain type, regardless of the mode of operation that a hybrid vehicle was in at the time of collision (hybrid vehicles typically start in electric mode and change from battery to combustion engine at higher speeds). 13

The outcome of interest was a pedestrian casualty.

Effect modification by road environment

We used the urban–rural classification 14 of the roads on which the collisions occurred to investigate whether casualty rate ratios comparing E-HE with ICE vehicles differed between rural and urban environments.

Data sources/measurement

Numerator data (numbers of pedestrians injured in collisions) were extracted from the Road Safety Data (STATS19) datasets. 15

Denominator data (100 million miles of car travel per year) were estimated by multiplying average annual mileage by numbers of vehicle registrations. 16 Average annual mileage for E-HE and ICE vehicles was estimated separately for urban and rural environments using data obtained under special licence from the National Travel Survey (NTS) datasets. 17 We estimated average annual mileage for the years 2013–2017 because the NTS variable for the vehicle fuel type did not include ‘hybrid’ prior to 2013 and data from 2018 had not been uploaded to the UK data service due to problems with the archiving process (Andrew Kelly, Database Manager, NTS, Department for Transport, 23 March 2020, personal communication). Denominators were thus available for the years 2013–2017.

Data preparation

The datasets for collisions, casualties and vehicles from the STATS19 database were merged using a unique identification number for each collision.

Statistical methods

We calculated annual casualty rates for E-HE and ICE vehicles separately and we compared these by calculating a rate ratio. We used Poisson regression models to estimate rate ratios with 95% CIs and to investigate any modifying effects of the road environment in which the collisions occurred. For this analysis, our regression model included explanatory terms for the main effects of the road environment, plus terms for the interaction between type of propulsion and the road environment. The assumptions for Poisson regression were met in our study: we modelled count data (counts of pedestrians injured), traffic collisions were independent of each other, occurring in different places over time, and never occurring simultaneously. Data preparation, management and analyses were carried out using Microsoft Access 2019 and Stata V.16. 18

Sensitivity analysis

We conducted an extreme case analysis where all missing propulsion codes were assumed to be ICE vehicles (there were over a 100 times more ICE vehicles than E-HE vehicles on the roads in Great Britain during our study period, 16 so missing propulsion is more likely to have been ICE).

The sample size for this study included all available recorded road traffic collisions in Great Britain during the study period. We estimated that for our study to have 80% power at the 5% significance level to show a difference in casualty rates of 2 per 100 miles versus 5.5 per 100 miles, we would require 481 million miles of vehicle travel in each group (E-HE and ICE); whereas to have 90% power at the 1% significance level to show this difference, 911 million miles of vehicle travel would be required in each group. Our study includes 32 000 million miles of E-HE vehicle travel and 3 000 000 million miles of ICE vehicle travel and therefore our study was sufficiently powered to detect differences in casualty rates of these magnitudes.

Between 2013 and 2017, there were 916 713 casualties from reported road traffic collisions in Great Britain. 120 197 casualties were pedestrians. Of these pedestrians, 96 285 had been hit by a car or taxi. Most pedestrians—71 666 (74%) were hit by an ICE car or taxi. 1652 (2%) casualties were hit by an E-HE car or taxi. For 22 829 (24%) casualties, the vehicle propulsion code was missing. Most collisions occurred in urban environments and a greater proportion of the collisions with E-HE vehicles occurred in an urban environment (94%) than did collisions with ICE vehicles (88%) ( figure 1 ).

Main results

During the period 2013 to 2017, the average annual casualty rates of pedestrians per 100 million miles were 5.16 (95% CI 4.92 to 5.42) for E-HE vehicles and 2.40 (95% CI 2.38 to 2.41) for ICE vehicles, which indicates that collisions with pedestrians were on average twice as likely (RR 2.15 (95% CI 2.05 to 2.26), p<0.001) with E-HE vehicles as with ICE vehicles ( table 1 ).

Pedestrian casualties due to collisions with cars or taxis from reported road traffic collisions in Great Britain 2013–2017—by vehicle propulsion type

In our extreme case analysis, the 22 829 pedestrian casualties where vehicle propulsion was missing were all assumed to have been struck by ICE vehicles. In this case, average casualty rates of pedestrians per 100 million miles were 3.16 (95% CI 3.14 to 3.18) for ICE vehicles, which would indicate that collisions with pedestrians were on average 63% more likely (RR 1.63 (95% CI 1.56 to 1.71), p<0.001) with E-HE vehicles than with ICE vehicles ( table 2 ).

Relative risks according to road environment

Casualty rates were higher in urban than rural environments ( tables 3 and 4 ).

Pedestrian casualties due to collisions with cars or taxis from reported road traffic collisions in Great Britain 2013–2017—by vehicle propulsion type in rural road environments

Urban environments

Collisions with pedestrians in urban environments were on average over two and a half times as likely (RR 2.69 (95% CI 2.56 to 2.83, p<0.001) with E-HE vehicles as with ICE vehicles ( table 3 ).

The extreme case sensitivity analysis showed collisions with pedestrians in urban environments were more likely with E-HE vehicles (RR 2.05; 95% CI 1.95 to 2.15).

Rural environments

Collisions with pedestrians in rural environments were equally likely (RR 0.91; 95% CI 0.74 to 1.11) with E-HE vehicles as with ICE vehicles ( table 4 ).

The extreme case sensitivity analysis found evidence that collisions with pedestrians in rural environments were less likely with E-HE vehicles (RR 0.68; 95% CI 0.55 to 0.83).

Results of Poisson regression analysis

Our Poisson regression model results ( table 5 ) showed that pedestrian injury rates were on average 9.28 (95% CI 9.07 to 9.49) times greater in urban than in rural environments. There was no evidence that E-HE vehicles were more dangerous than ICE vehicles in rural environments (RR 0.91; 95% CI 0.74 to 1.11), consistent with our finding in table 4 . There was strong evidence that E-HE vehicles were on average three times more dangerous than ICE vehicles in urban environments (RR 2.97; 95% CI 2.41 to 3.67).

Statement of principal findings

This study found that in Great Britain between 2013 and 2017, casualty rates of pedestrians due to collisions with E-HE cars and taxis were higher than those due to collisions with ICE cars and taxis. Our best estimate is that such collisions are on average twice as likely, and in urban areas E-HE vehicles are on average three times more dangerous than ICE vehicles, consistent with the theory that E-HE vehicles are less audible to pedestrians in urban areas where background ambient noise levels are higher.

Strengths and weaknesses of the study

There are several limitations to this study which are discussed below.

The data used were not very recent. However, ours is the most current analysis of E-HE vehicle collisions using the STATS19 dataset.

Before we can infer that E-HE vehicles pose a greater risk to pedestrians than ICE vehicles, we must consider whether our study is free from confounding and selection bias. Confounding occurs when the exposure and outcome share a common cause. 19 Confounders in this study would be factors that may both cause a traffic collision and also cause the exposure (use of an E-HE car). Younger, less experienced drivers (ie, ages 16–24) are more likely to be involved in a road traffic collision 20 and are also more likely to own an electric car. 21 Some of the observed increased risk of electric cars may therefore be due to younger drivers preferring electric cars. This would cause positive confounding, meaning that the true relative risk of electric cars is less than we have estimated in our study. Regarding selection bias, it is known that the STATS19 dataset does not include every road traffic casualty in Great Britain, as some non-fatal casualties are not reported to the police. 22 If casualties from collisions are reported to the police differentially according to the type of vehicle propulsion, this may have biased our results; however, there is no reason to suspect that a pedestrian struck by a petrol or diesel car is any more or less likely to report the collision to the police than one struck by an electric car.

We must also address two additional concerns as ours is a cross-sectional study: The accuracy of exposure assignment (including the potential for recall bias) and the adequacy of prevalence as a proxy for incidence. 23 First, the accuracy of exposure assignment and the potential for recall bias are not issues for this study, as the exposure (type of propulsion of the colliding vehicle, E-HE or ICE), is assigned independently of the casualties by the UK Department for Transport who link the vehicle registration number (VRN) of each colliding vehicle to vehicle data held by the UK Driver Vehicle and Licensing Agency (DVLA). 10 Second, we have not used prevalence as a proxy for incidence but have estimated incidence using total distance travelled by cars as the measure of exposure.

We may therefore reasonably infer from our study results that E-HE vehicles pose a greater risk to pedestrians than ICE vehicles in urban environments, and that part of the risk may be due to younger people’s preference for E-HE cars.

A major limitation of the STATS19 road safety dataset used in this study was that it did not contain a vehicle propulsion code for all vehicles in collisions with pedestrians. We excluded these vehicles from our primary analysis (a complete case analysis) and we also conducted an extreme case sensitivity analysis. We will now argue why imputation of missing vehicle propulsion codes would not have added value to this study. Vehicle propulsion data are obtained for the STATS19 dataset by the UK Department for Transport who link the VRN of each colliding vehicle recorded in STATS19 to vehicles data held by the UK DVLA. The STATS19 data on reported collisions and casualties are collected by a Police Officer when an injury road accident is reported to them; Most police officers write details of the casualties and the vehicles involved in their notebooks for transcription onto the STATS19 form later at the Police station. 24 The VRN is one of 18 items recorded on each vehicle involved in a collision. Items may occasionally be missed due to human error during this process. Where a VRN is missing, vehicle propulsion will be missing in the STATS19 dataset. The chance that any vehicle-related item is missing will be independent of any characteristics of the casualties involved and so the vehicle propulsion codes are missing completely at random (MCAR). As the missing propulsion data are very likely MCAR, the set of pedestrians with no missing data is a random sample from the source population and hence our complete case analysis for handling the missing data gives unbiased results. The extreme case sensitivity analysis we performed shows a possible result that could occur, and it demonstrates our conclusions in urban environments are robust to the missing data. Lastly, to impute the missing data would require additional variables which are related to the likelihood of a VRN being missing. Such variables were not available and therefore we do not believe a useful multiple imputation analysis could have been performed.

Strengths and weaknesses in relation to other studies

Our study uses hundreds of millions of miles of car travel as the denominators in our estimates of annual pedestrian casualty rates which is a more accurate measure of exposure to road hazards than the number of registered vehicles, which was used as the denominator in a previous study in the UK. 10 Our results differ to this previous study which found that pedestrian casualty rates from collisions with E-HE vehicles during 2005–2007 were lower than those from ICE vehicles. Our study has updated this previous analysis and shows that casualty rates due to E-HE vehicle collisions exceed those due to ICE vehicle collisions. Similarly, our study uses a more robust measure of risk (casualty rates per miles of car travel) than that used in a US study. 9 Our study results are consistent with this US study that found that the odds of an E-HE vehicle causing a pedestrian injury were 35% greater than an ICE vehicle. Brand et al 8 hypothesised, without any supporting data, that “hybrid and electric low-noise cars cause an increase in traffic collisions involving vulnerable road users in urban areas” and recommended that “further investigations have to be done with the increase of low-noise cars to prove our hypothesis right.” 8 We believe that our study is the first to provide empirical evidence in support of this hypothesis.

Meaning of the study: possible explanations and implications for clinicians and policymakers

More pedestrians are injured in Great Britain by petrol and diesel cars than by electric cars, but compared with petrol and diesel cars, electric cars pose a greater risk to pedestrians and the risk is greater in urban environments. One plausible explanation for our results is that background ambient noise levels differ between urban and rural areas, causing electric vehicles to be less audible to pedestrians in urban areas. Such differences may impact on safety because pedestrians usually hear traffic approaching and take care to avoid any collision, which is more difficult if they do not hear electric vehicles. This is consistent with audio-testing evidence in a small study of vision-impaired participants. 10 From a Public Health perspective, our results should not discourage active forms of transport beneficial to health, such as walking and cycling, rather they can be used to ensure that any potential increased traffic injury risks are understood and safeguarded against. A better transport policy response to the climate emergency might be the provision of safe, affordable, accessible and integrated public transport systems for all. 25

Unanswered questions and future research

It will be of interest to investigate the extent to which younger drivers are involved in collisions of E-HE cars with pedestrians.

If the braking distance of electric cars is longer, 26 and electric cars are heavier than their petrol and diesel counterparts, 27 these factors may increase the risks and the severity of injuries sustained by pedestrians and require investigation.

As car manufacturers continue to develop and equip new electric cars with Collision Avoidance Systems and Autonomous Emergency Braking to ensure automatic braking in cases where pedestrians or cyclists move into the path of an oncoming car, future research can repeat the analyses presented in this study to evaluate whether the risks of E-HE cars to pedestrians in urban areas have been sufficiently mitigated.

Conclusions

E-HE vehicles pose a greater risk to pedestrians than petrol and diesel powered vehicles in urban environments. This risk needs to be mitigated as governments proceed to phase out petrol and diesel cars.
