How to write a literature review introduction (+ examples)

The introduction to a literature review serves as your reader’s guide through your academic work and thought process. Explore the significance of literature review introductions in review papers, academic papers, essays, theses, and dissertations. We delve into the purpose and necessity of these introductions, explore the essential components of literature review introductions, and provide step-by-step guidance on how to craft your own, along with examples.

Why you need an introduction for a literature review

In academic writing , the introduction for a literature review is an indispensable component. Effective academic writing requires proper paragraph structuring to guide your reader through your argumentation. This includes providing an introduction to your literature review.

It is imperative to remember that you should never start sharing your findings abruptly. Even if there isn’t a dedicated introduction section .

When you need an introduction for a literature review

There are three main scenarios in which you need an introduction for a literature review:

What to include in a literature review introduction

It is crucial to customize the content and depth of your literature review introduction according to the specific format of your academic work.

In practical terms, this implies, for instance, that the introduction in an academic literature review paper, especially one derived from a systematic literature review , is quite comprehensive. Particularly compared to the rather brief one or two introductory sentences that are often found at the beginning of a literature review section in a standard academic paper. The introduction to the literature review chapter in a thesis or dissertation again adheres to different standards.

Academic literature review paper

The introduction of an academic literature review paper, which does not rely on empirical data, often necessitates a more extensive introduction than the brief literature review introductions typically found in empirical papers. It should encompass:

Regular literature review section in an academic article or essay

In a standard 8000-word journal article, the literature review section typically spans between 750 and 1250 words. The first few sentences or the first paragraph within this section often serve as an introduction. It should encompass:

In some cases, you might include:

Introduction to a literature review chapter in thesis or dissertation

Some students choose to incorporate a brief introductory section at the beginning of each chapter, including the literature review chapter. Alternatively, others opt to seamlessly integrate the introduction into the initial sentences of the literature review itself. Both approaches are acceptable, provided that you incorporate the following elements:

Examples of literature review introductions

Example 1: an effective introduction for an academic literature review paper.

To begin, let’s delve into the introduction of an academic literature review paper. We will examine the paper “How does culture influence innovation? A systematic literature review”, which was published in 2018 in the journal Management Decision.

Example 2: An effective introduction to a literature review section in an academic paper

The second example represents a typical academic paper, encompassing not only a literature review section but also empirical data, a case study, and other elements. We will closely examine the introduction to the literature review section in the paper “The environmentalism of the subalterns: a case study of environmental activism in Eastern Kurdistan/Rojhelat”, which was published in 2021 in the journal Local Environment.

Thus, the author successfully introduces the literature review, from which point onward it dives into the main concept (‘subalternity’) of the research, and reviews the literature on socio-economic justice and environmental degradation.

Examples 3-5: Effective introductions to literature review chapters

Numerous universities offer online repositories where you can access theses and dissertations from previous years, serving as valuable sources of reference. Many of these repositories, however, may require you to log in through your university account. Nevertheless, a few open-access repositories are accessible to anyone, such as the one by the University of Manchester . It’s important to note though that copyright restrictions apply to these resources, just as they would with published papers.

Master’s thesis literature review introduction

The last example is the doctoral thesis Metacognitive strategies and beliefs: Child correlates and early experiences Chan, K. Y. M. (Author). 31 Dec 2020 . The author clearly conducted a systematic literature review, commencing the review section with a discussion of the methodology and approach employed in locating and analyzing the selected records.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

Prevent plagiarism. Run a free check.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

• To develop a theory or evaluate an existing theory
• To summarize the historical or existing state of a research topic
• Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

• A research paper assigned in a course
• A thesis or dissertation
• A grant proposal
• An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

• Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework:  10.1177/08948453211037398  

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

• Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

How to write a literature review in 6 steps

What is a literature review?

How to write a literature review, 1. determine the purpose of your literature review, 2. do an extensive search, 3. evaluate and select literature, 4. analyze the literature, 5. plan the structure of your literature review, 6. write your literature review, other resources to help you write a successful literature review, frequently asked questions about writing a literature review, related articles.

A literature review is an assessment of the sources in a chosen topic of research.

A good literature review does not just summarize sources. It analyzes the state of the field on a given topic and creates a scholarly foundation for you to make your own intervention. It demonstrates to your readers how your research fits within a larger field of study.

In a thesis, a literature review is part of the introduction, but it can also be a separate section. In research papers, a literature review may have its own section or it may be integrated into the introduction, depending on the field.

➡️ Our guide on what is a literature review covers additional basics about literature reviews.

• Identify the main purpose of the literature review.
• Do extensive research.
• Evaluate and select relevant sources.
• Analyze the sources.
• Plan a structure.
• Write the review.

In this section, we review each step of the process of creating a literature review.

In the first step, make sure you know specifically what the assignment is and what form your literature review should take. Read your assignment carefully and seek clarification from your professor or instructor if needed. You should be able to answer the following questions:

• How many sources do I need to include?
• What types of sources should I review?
• Should I evaluate the sources?
• Should I summarize, synthesize or critique sources?
• Do I need to provide any definitions or background information?

In addition to that, be aware that the narrower your topic, the easier it will be to limit the number of sources you need to read in order to get a good overview of the topic.

Now you need to find out what has been written on the topic and search for literature related to your research topic. Make sure to select appropriate source material, which means using academic or scholarly sources , including books, reports, journal articles , government documents and web resources.

➡️ If you’re unsure about how to tell if a source is scholarly, take a look at our guide on how to identify a scholarly source .

Come up with a list of relevant keywords and then start your search with your institution's library catalog, and extend it to other useful databases and academic search engines like:

• Google Scholar
• Science.gov

➡️ Our guide on how to collect data for your thesis might be helpful at this stage of your research as well as the top list of academic search engines .

Once you find a useful article, check out the reference list. It should provide you with even more relevant sources. Also, keep a note of the:

• authors' names
• page numbers

Keeping track of the bibliographic information for each source will save you time when you’re ready to create citations. You could also use a reference manager like Paperpile to automatically save, manage, and cite your references.

Read the literature. You will most likely not be able to read absolutely everything that is out there on the topic. Therefore, read the abstract first to determine whether the rest of the source is worth your time. If the source is relevant for your topic:

• Read it critically.
• Look for the main arguments.
• Take notes as you read.
• Organize your notes using a table, mind map, or other technique.

Now you are ready to analyze the literature you have gathered. While your are working on your analysis, you should ask the following questions:

• What are the key terms, concepts and problems addressed by the author?
• How is this source relevant for my specific topic?
• How is the article structured? What are the major trends and findings?
• What are the conclusions of the study?
• How are the results presented? Is the source credible?
• When comparing different sources, how do they relate to each other? What are the similarities, what are the differences?
• Does the study help me understand the topic better?
• Are there any gaps in the research that need to be filled? How can I further my research as a result of the review?

Tip: Decide on the structure of your literature review before you start writing.

There are various ways to organize your literature review:

• Chronological method : Writing in the chronological method means you are presenting the materials according to when they were published. Follow this approach only if a clear path of research can be identified.
• Thematic review : A thematic review of literature is organized around a topic or issue, rather than the progression of time.
• Publication-based : You can order your sources by publication, if the way you present the order of your sources demonstrates a more important trend. This is the case when a progression revealed from study to study and the practices of researchers have changed and adapted due to the new revelations.
• Methodological approach : A methodological approach focuses on the methods used by the researcher. If you have used sources from different disciplines that use a variety of research methods, you might want to compare the results in light of the different methods and discuss how the topic has been approached from different sides.

Regardless of the structure you chose, a review should always include the following three sections:

• An introduction, which should give the reader an outline of why you are writing the review and explain the relevance of the topic.
• A body, which divides your literature review into different sections. Write in well-structured paragraphs, use transitions and topic sentences and critically analyze each source for how it contributes to the themes you are researching.
• A conclusion , which summarizes the key findings, the main agreements and disagreements in the literature, your overall perspective, and any gaps or areas for further research.

The goal of a literature review is to asses the state of the field on a given topic in preparation for making an intervention.

A literature review should have its own independent section. You should indicate clearly in the table of contents where it can be found, and address this section as “Literature Review.”

There is no set amount of words for a literature review; the length depends on the research. If you are working with a large amount of sources, then it will be long. If your paper does not depend entirely on references, then it will be short.

Most research papers include a literature review. By assessing the available sources in your field of research, you will be able to make a more confident argument about the topic.

Literature reviews are most commonly found in theses and dissertations. However, you find them in research papers as well.

How to Write a Systematic Review Introduction

Automate every stage of your literature review to produce evidence-based research faster and more accurately.

How to write an introduction of a systematic review.

For anyone who has experience working on any sort of study, be it a review, thesis, or even just an academic paper – writing an introduction shouldn’t be a foreign concept. It generally follows the same rules, requiring it to give the readers the context of the study explaining what the review is all about: the topic it tackles, why the study was performed and the goals of its findings.

That said, most systematic reviews are governed by two guidelines that help improve the reporting of the research. These are the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement and the Cochrane handbook. Both have specifications on how to write the report, including the introduction. Look at a systematic review example , and you’ll find that it uses either one of these frameworks.

What Is The Right Length Of A Systematic Review Introduction?

There’s no hard and fast rule about the length of a systematic review introduction. However, it’s best to keep it concise. Limit it to just two to four paragraphs, not exceeding one full page. Don’t worry, you’ll have the rest of the paper to fill with data!

What To Include In A Systematic Review Introduction

Whether or not you’re following writing guidelines, here are some pieces of information that you should include in your systematic review introduction:

Give background information about the review, including what’s already known about the topic and what you’re attempting to discover with your findings.

Definitions

This is optional, but if your review is dealing with important terms and concepts that require defining beforehand for better understanding on the readers’ part, add them to your introduction.

Delve a little into why the study topic is important, and why a systematic review must be done for it. This prompts a discussion about the knowledge gaps, a lack of cohesion in existing studies, and the potential implications of the review.

Research Question

Introduce your topic, specifically the research question that’s driving the study. Be sure that it’s new, focused, specific, and answerable, and that it ties together with your conclusion later on.

How to write a superb literature review

Andy Tay is a freelance writer based in Singapore.

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

Structure of a literature review

Determine your purpose.

Work out what you need to address in the literature review. What are you being asked to do in your literature review? What are you searching the literature to discover? Check your assignment question and your criteria sheet to know what to focus on.

Do an extensive search of the literature

Find out what has been written on the topic.

What kind of literature?

Select appropriate source material: Use a variety of academic or scholarly sources that are relevant, current and authoritative. An extensive review of relevant material will include — books, journal articles, reports, government documents, conference proceedings and web resources. The Library would be the best place to search for your sources.

How many resources?

The number of sources that you will be required to review will depend on what the literature review is for and how advanced you are in your studies. It could be from five sources at first year undergraduate level to more than fifty for a thesis. Your lecturer will advise you on these details.

Note the bibliographical details of your sources

Keep a note of the publication title, date, authors’ names, page numbers and publishers. These details will save you time later.

Read the literature

• Critically read each source, look for the arguments presented rather than for facts.
• Take notes as you read and start to organise your review around themes and ideas.
• Consider using a table, matrix or concept map to identify how the different sources relate to each other.

Analyse the literature you have found

In order for your writing to reflect strong critical analysis, you need to evaluate the sources. For each source you are reviewing ask yourself these questions:

• What are the key terms and concepts?
• How relevant is this article to my specific topic?
• What are the major relationships, trends and patterns?
• How has the author structured the arguments?
• How authoritative and credible is this source?
• What are the differences and similarities between the sources?
• Are there any gaps in the literature that require further study?

Write the review

• Start by writing your thesis statement. This is an important introductory sentence that will tell your reader what the topic is and the overall perspective or argument you will be presenting.
• Like essays, a literature review must have an introduction, a body and a conclusion.

Introduction

Your introduction should give an outline of:

• why you are writing a review, and why the topic is important
• the scope of the review — what aspects of the topic will be discussed
• the criteria used for your literature selection (e.g. type of sources used, date range)
• the organisational pattern of the review.

Body paragraphs

Each body paragraph should deal with a different theme that is relevant to your topic. You will need to synthesise several of your reviewed readings into each paragraph, so that there is a clear connection between the various sources. You will need to critically analyse each source for how they contribute to the themes you are researching.

The body could include paragraphs on:

• historical background
• methodologies
• previous studies on the topic
• mainstream versus alternative viewpoints
• principal questions being asked
• general conclusions that are being drawn.

Your conclusion should give a summary of:

• the main agreements and disagreements in the literature
• any gaps or areas for further research
• your overall perspective on the topic.
• outlined the purpose and scope?
• identified appropriate and credible (academic/scholarly) literature?
• recorded the bibliographical details of the sources?
• analysed and critiqued your readings?
• identified gaps in the literature and research?
• explored methodologies / theories / hypotheses / models?
• discussed the varying viewpoints?
• written an introduction, body and conclusion?
• checked punctuation and spelling?

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question.  That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

• Explains the background of research on a topic.
• Demonstrates why a topic is significant to a subject area.
• Discovers relationships between research studies/ideas.
• Identifies major themes, concepts, and researchers on a topic.
• Identifies critical gaps and points of disagreement.
• Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question.  The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

• Make sure your research question is not too broad or too narrow.  Is it manageable?
• Begin writing down terms that are related to your question. These will be useful for searches later.
• If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

• This may depend on your assignment.  How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search. 

Where to find databases:

• use the tabs on this guide
• Find other databases in the Nursing Information Resources web page
• More on the Medical Library web page
• ... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

• Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
• Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
• Review the abstracts of research studies carefully. This will save you time.
• Use the bibliographies and references of research studies you find to locate others.
• Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
• Ask your librarian for help at any time.
• Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

• What was the research question of the study you are reviewing? What were the authors trying to discover?
• Was the research funded by a source that could influence the findings?
• What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
• Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
• If there are conflicting studies, why do you think that is?
• How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips: 

• Review the abstracts carefully.  
• Keep careful notes so that you may track your thought processes during the research process.
• Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

The Most Important Thing

The best time to write an introduction is AFTER you write the body of your paper.

Well, how do you know what to introduce until after you've figured out what you want to say?

The best time to write an introduction is as one of the last things you do.

Basic Introduction Template

For any other sort of scholarly writing, the following basic structure works well for an introduction:

• What has been said or done on this topic?  
• What is the problem with what has been said or done?
• What will you offer to solve the problem?  (The answer to this is your thesis statement.)
• How does your solution address necessary change?

Writing an Introduction

The job of an introduction is to preview what you are going to say so the audience knows what is coming.  A good introduction starts out generally and works towards a specific statement of what you intend to discuss in your writing. 

The introduction explains the focus and establishes the importance of the subject. It discusses what kind of work has been done on the topic and identifies any controversies within the field or any recent research which has raised questions about earlier assumptions. It may provide background or history, and it indicates why the topic is important, interesting, problematic, or relevant in some way.  It concludes with a purpose or thesis statement. In a stand-alone literature review, this statement will sum up and evaluate the state of the art in this field of research; in a review that is an introduction or preparatory to a larger work, such as the Culminating Project, it will suggest how the review findings will lead to the research the writer proposes to undertake.

In a literature review, an introduction may contain the following:

• A concise definition of a topic under consideration (this may be a descriptive or argumentative thesis, or proposal), as well as the scope of the related literature being investigated. (Example: If the topic under consideration is ‘women’s wartime diaries’, the scope of the review may be limited to published or unpublished works, works in English, works from a particular location, time period, or conflict, etc.)  
• The introduction should also note what topics are being included and what are intentional exclusions. (Example: “This review will not explore the diaries of adolescent girls.”)
• A final sentence should signal the list of key topics that will be used to discuss the selected sources.

Many theories have been proposed to explain what motivates human behavior. Although the literature covers a wide variety of such theories, this review will focus on five major themes which emerge repeatedly throughout the literature reviewed. These themes are incorporation of the self-concept into traditional theories of motivation, the influence of rewards on motivation, the increasing importance of internal forces of motivation, autonomy and self-control as sources of motivation, and narcissism as an essential component of motivation. Although the literature presents these themes in a variety of contexts, this paper will primarily focus on their application to self-motivation.

Let's break that apart.

Literature Review Tips for the Introduction and Discussion Sections

A literature review is a summary of studies related to a particular area of research. It identifies and summarizes all the relevant research conducted on a particular topic. It is important that your literature review is focused . Therefore, you should choose a limited number of studies that are central to your topic rather than trying to collect a wide range of studies that might not be closely connected.

Literature reviews help you accomplish the following:

• Evaluate past research  Collecting relevant resources will help you see what research has already been done. This will also help avoid duplication.
• Identify experts It is important to identify credible researchers who have knowledge in a given field, in order to seek their help if you get stuck with certain aspects of your research.
• Identify key questions  Your ultimate aim is to bring something new to the conversation. Collecting resources will help you determine the important questions that need to be addressed.
• Determine methodologies used in past studies Knowing how others have approached a particular topic will give you the opportunity to identify problems and find new ways to research and study a topic. If the reported methodology was successful, you can use it and save time that you would otherwise be spending on optimization.

Presenting Literature Review in the Introduction and Discussion Sections

There are many benefits to presenting literature reviews in the introduction and discussion sections of your manuscripts . However, there are differences in how you can present literature reviews in each section.

What Should be Included in the Literature Review of the Introduction Section?

The literature reviewed in the introduction should:

• Introduce the topic
• Establish the significance of the study
• Provide an overview of the relevant literature
• Establish a context for the study using the literature
• Identify knowledge gaps
• Illustrate how the study will advance knowledge on the topic

As you can see, literature review plays a significant role in the introduction section. However, there are some things that you should avoid doing in this section. These include:

• Elaborating on the studies mentioned in the literature review
• Using studies from the literature review to aggressively support your research
• Directly quoting studies from the literature review

It is important to know how to integrate the literature review into the introduction in an effective way. Although you can mention other studies, they should not be the focus. Instead, focus on using the literature review to aid in setting a foundation for the manuscript.

What Goes in the Literature Review of the Discussion Section?

Literature reviews play an important role in the discussion section of a manuscript . In this section, your findings should be the focus, rather than those of other researchers. Therefore, you should only use the studies mentioned in the literature review as support and evidence for your study.

There are three ways in which you can use literature reviews in the discussion section:

• To Provide Context for Your Study Using studies from the literature review helps to set the foundation for how you will reveal your findings and develop your ideas.
• Compare your Findings to Other Studies You can use previous literature as a backdrop to compare your new findings. This helps describe and also advance your ideas.
• State the Contribution of Your Study In addition to developing your ideas, you can use literature reviews to explain how your study contributes to the field of study.

However, there are three common mistakes that researchers make when including literature reviews in the discussion section. First, they mention all sorts of studies, some of which are not even relevant to the topic under investigation. Second, instead of citing the original article, they cite a related article that mentions the original article. Lastly, some authors cite previous work solely based on the abstract, without even going through the entire paper.

We hope this article helps you effectively present your literature review in both the introduction as well as the discussion section of your manuscript. You can also mention any other tips that will add to this article in the comments section below.

• Planning for length
• Planning for content
• Abstracts, tone, unity of style
• General comments

A literature review should be structured like any other essay: it should have an introduction, a middle or main body, and a conclusion.

The introduction should:

• define your topic and provide an appropriate context for reviewing the literature;
• establish your reasons – i.e. point of view – for
• reviewing the literature;
• explain the organisation – i.e. sequence – of the review;
• state the scope of the review – i.e. what is included and what isn’t included. For example, if you were reviewing the literature on obesity in children you might say something like: There are a large number of studies of obesity trends in the general population. However, since the focus of this research is on obesity in children, these will not be reviewed in detail and will only be referred to as appropriate.

The middle or main body should:

• organise the literature according to common themes;
• provide insight into the relation between your chosen topic and the wider subject area e.g. between obesity in children and obesity in general;
• move from a general, wider view of the literature being reviewed to the specific focus of your research.

The conclusion should:

• summarise the important aspects of the existing body of literature;
• evaluate the current state of the literature reviewed;
• identify significant flaws or gaps in existing knowledge;
• outline areas for future study;
• link your research to existing knowledge.

Ten Simple Rules for Writing a Literature Review

Marco pautasso.

1 Centre for Functional and Evolutionary Ecology (CEFE), CNRS, Montpellier, France

2 Centre for Biodiversity Synthesis and Analysis (CESAB), FRB, Aix-en-Provence, France

Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .

When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.

Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.

Rule 1: Define a Topic and Audience

How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:

• interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
• an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
• a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).

Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).

Rule 2: Search and Re-search the Literature

After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:

• keep track of the search items you use (so that your search can be replicated [10] ),
• keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
• use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
• define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
• do not just look for research papers in the area you wish to review, but also seek previous reviews.

The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .

• discussing in your review the approaches, limitations, and conclusions of past reviews,
• trying to find a new angle that has not been covered adequately in the previous reviews, and
• incorporating new material that has inevitably accumulated since their appearance.

When searching the literature for pertinent papers and reviews, the usual rules apply:

• be thorough,
• use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
• look at who has cited past relevant papers and book chapters.

Rule 3: Take Notes While Reading

If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.

Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.

Rule 4: Choose the Type of Review You Wish to Write

After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.

There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .

Rule 5: Keep the Review Focused, but Make It of Broad Interest

Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.

While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.

Rule 6: Be Critical and Consistent

Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:

• the major achievements in the reviewed field,
• the main areas of debate, and
• the outstanding research questions.

It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.

Rule 7: Find a Logical Structure

Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .

How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .

Rule 8: Make Use of Feedback

Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.

Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .

Rule 9: Include Your Own Relevant Research, but Be Objective

In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.

In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.

Rule 10: Be Up-to-Date, but Do Not Forget Older Studies

Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.

Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.

Tips for writing an Introduction for a literature review

A well-crafted introduction for a literature review identifies the tone of your article and helps the reader realize the context and aims of your review.

The introduction should be informative and engaging enough to guide the reader through the complex landscape of existing research.

Let’s get familiar with important tips for writing a literature review introduction:

·         Start with a hook

begin with an engaging opening sentence that captures the reader’s attention on the article’s Topic.

You can use a thought-provoking question, a surprising fact, or a brief story in the literature review introduction. The goal is to make your introduction persuasive and relevant to your research.

After the starting sentence, which we call a hook, you need to provide some background information about the general subject area or field of study.

Explain why the Topic is important right now and relevant, and highlight any gaps or issues that your literature review will address.

·         Define the scope

Clearly define the scope of your literature review in the introduction part. Explain the specific aspects of the Topic or the research questions, which helps the reader understand what to expect and the boundaries of your review.

·         Give a brief & organized Literature.

You need to give a brief overview of how you’ve organized the literature review in the introduction. Reference the key themes, categories, or methods you will be using to categorize and analyze the reviewed sources.

·         Smoothly shift to the Main Body.

To end the literature review’s introduction more conveniently, you can summarize the key points that you will discuss in the subsequent sections and present an outline of the review’s structure. Or just simply state that you will explore the existing Literature in the next part.

·         Be Clear & Concise

To have the best intro, keep the literature review introduction concise and focused. Stay away from unnecessary jargon or overly complex language. The primary aim is to write a clear and engaging opening for the literature review.

·         Read, revise, and edit. Then do it again.

Finally, it is vital to revise and edit your introduction to confirm its clarity, coherence, and smooth flow of ideas. It should align with the overall tone and structure of your paper.

If you are still confused by all the tips, let’s make this clearer with some examples:

How To Write A Literature Review Introduction: A Quick Guide

By Laura Brown on 5th July 2023

When it comes to writing an introduction to a literature review, there are a few key steps to keep in mind. Start by clearly stating the purpose and scope of your review. Then, provide a brief overview of the main themes or concepts you will address. It’s important to engage your readers from the start with a compelling opening paragraph that hooks their interest. Lastly, establish the background and context of your research and outline the objectives of your review. So, these components can be summarised as,

• Background and context
• Objective and purpose
• Scope and inclusion/exclusion criteria
• Research questions or hypotheses
• Organisation and structure
• Signposting
• Methodology (optional)

Now, if you’re a student or researcher diving into the world of literature reviews, you’ve come to the right place. Crafting an effective introduction is crucial to engage your readers and set the stage for your review. In this guide, we will walk you through ten essential steps to help you create a captivating introduction with perfection. From understanding the purpose and scope to presenting the background and context, we’ve got you covered. So, let’s embark on this journey together and unlock the secrets on how to write a good introduction for a literature review that grabs attention.

Step 1: Clarify The Purpose And Scope Of Your Literature Review

Before diving into writing, it’s essential to gain a clear understanding of its purpose and scope and be aware of how to start it. Begin with defining the overarching goal of your review. Are you aiming to provide a comprehensive overview of existing primary and secondary research on a specific topic? Or perhaps you’re focusing on a particular aspect or gap in the literature?

Additionally, determine the scope of your review by identifying the timeframe, geographical area, or specific disciplines you will cover. Clearly defining the purpose and scope will not only help you stay focused, but also ensure that your introduction sets the right expectations for your readers.

Step 2: Identify The Main Themes Or Concepts You’ll Address

To create a good literature review introduction structure, it’s crucial to identify and articulate the main themes or concepts that will be the focus of your review. Take some time to analyse the body of literature you have gathered and identify recurring ideas, theories, or key areas of discussion.

These themes or concepts will serve as the foundation for organising your review and guiding your readers through the subsequent sections. By clearly identifying and introducing these main themes or concepts in your introduction, you provide readers with a roadmap of what to expect and demonstrate your understanding of the existing knowledge within your field.

Step 3: Conduct A Comprehensive Search For Relevant Academic Sources

To ensure the credibility and depth of your literature review, embark on a thorough search for relevant academic sources. Utilise scholarly databases, online libraries, and search engines to locate articles, books, conference papers, and other reputable sources related to your research topic.

Cast a wide net to gather a comprehensive collection of materials that provide diverse perspectives and insights. Pay attention to keywords, use advanced search techniques, and explore bibliographies of relevant sources to uncover hidden gems. Conducting a comprehensive literature search will let you lay the groundwork for a well-informed and robust review.

Step 4: Evaluate And Select The Most Appropriate Sources.

Once you have accumulated a substantial number of potential sources, it’s essential to critically evaluate their quality, credibility, and relevance. Assess the authority of the authors, the reputation of the publishing journals or organisations, and the rigour of the research methodologies employed.

Scrutinise the relevance of each source to your research objectives and discard any that do not align with your focus. You should aim for a balanced mix of seminal works and recent publications to ensure the inclusion of both foundational knowledge and the latest advancements in your field.

Step 5: Organise Your Sources Based On Identified Themes Or Concepts

Now that you have a curated selection of relevant sources, it’s time to organise them based on the main themes or concepts you have identified. For this, look for common threads, recurring ideas, or distinct categories within the literature. Furthermore, create a system, such as using digital tools or physical note cards, to sort and categorise your sources accordingly.

Consider how each source contributes to each theme or concept, and make strategic decisions about their placement. By taking these steps, as suggested by Literature Review Writing Service , you can lay the groundwork for a coherent and cohesive literature review that flows seamlessly from one theme to another.

Step 6: Develop An Outline For Your Introduction

With a clear understanding of your literature review’s purpose, themes, organised sources and sufficient understanding of how to introduce a literature review , it’s time to develop an outline for your introduction. Firstly, consider the key points and sub-points you want to address. For this, begin with a concise overview of the main themes or concepts you will cover, followed by a logical progression of the sub-points that support and introduce each theme.

This outline will serve as a roadmap, ensuring that you can do it in a well-structured and coherent manner, effectively guiding your readers through the upcoming sections.

Step 7: Craft An Engaging Opening Paragraph

The opening paragraph plays a crucial role in capturing your reader’s attention and setting the tone for the rest of the review. It will take two simple steps to come up with a solid introduction.

• Start with a thought-provoking question, a captivating anecdote, or a surprising statistic related to your research topic.
• Provide a clear and concise overview of the purpose of your literature review, highlighting its significance and relevance to the field.

By creating an opening paragraph that piques curiosity and conveys the purpose, you set the stage for a captivating literature review. Still, if you find it difficult, you can ask Crowd Writer for literature review introduction examples.

Step 8: Provide Relevant Background Information And Context

After hooking your readers, it’s important to provide them with the necessary background information and context to understand the topic and its significance. This step involves introducing key concepts, theories, or historical developments that are relevant to your literature review.

In the 8th step on how to write an introduction for a literature review, briefly explain any terminology or jargon that may be unfamiliar to your readers. Additionally, highlight the gap or problem in the existing literature that your review aims to address.

Step 9: Clearly State The Objectives Of Your Literature Review

In this step, it’s important to explicitly state the objectives of your literature review. Clearly articulate what you aim to achieve through your review. You should identify gaps in the existing literature, synthesise and analyse the findings of previous studies, or propose new research directions.

State these objectives in a concise and focused manner. By doing so, you will be able to provide a roadmap for your readers and set expectations for the insights and outcomes they can expect from your literature review.

Step 10: Provide A Brief Preview Of The Main Sections

As you conclude your introduction, offer a brief preview of the main sections or themes that you will cover in your literature review. This serves as a roadmap for readers, giving them an overview of the content they can expect in the subsequent sections.

Provide a concise summary of the main points or sub-points you will explore, highlighting the significance of each section and how they contribute to your overall review. By providing this preview on the structure of a literature review , you create anticipation and guide readers through the logical flow of your literature review, ensuring they understand the structure and organisation of your work.

Structure of a Critical Review

Critical reviews, both short (one page) and long (four pages), usually have a similar structure. Check your assignment instructions for formatting and structural specifications. Headings are usually optional for longer reviews and can be helpful for the reader.

Introduction

The length of an introduction is usually one paragraph for a journal article review and two or three paragraphs for a longer book review. Include a few opening sentences that announce the author(s) and the title, and briefly explain the topic of the text. Present the aim of the text and summarise the main finding or key argument. Conclude the introduction with a brief statement of your evaluation of the text. This can be a positive or negative evaluation or, as is usually the case, a mixed response.

Present a summary of the key points along with a limited number of examples. You can also briefly explain the author’s purpose/intentions throughout the text and you may briefly describe how the text is organised. The summary should only make up about a third of the critical review.

The critique should be a balanced discussion and evaluation of the strengths, weakness and notable features of the text. Remember to base your discussion on specific criteria. Good reviews also include other sources to support your evaluation (remember to reference).

You can choose how to sequence your critique. Here are some examples to get you started:

• Most important to least important conclusions you make about the text.
• If your critique is more positive than negative, then present the negative points first and the positive last.
• If your critique is more negative than positive, then present the positive points first and the negative last.
• If there are both strengths and weakness for each criterion you use, you need to decide overall what your judgement is. For example, you may want to comment on a key idea in the text and have both positive and negative comments. You could begin by stating what is good about the idea and then concede and explain how it is limited in some way. While this example shows a mixed evaluation, overall you are probably being more negative than positive.
• In long reviews, you can address each criterion you choose in a paragraph, including both negative and positive points. For very short critical reviews (one page or less), where your comments will be briefer, include a paragraph of positive aspects  and another of negative.
• You can also include recommendations for how the text can be improved in terms of ideas, research approach; theories or frameworks used can also be included in the critique section.

Conclusion & References

This is usually a very short paragraph.

• Restate your overall opinion of the text.
• Briefly present recommendations.
• If necessary, some further qualification or explanation of your judgement can be included. This can help your critique sound fair and reasonable.

If you have used other sources in you review you should also include a list of references at the end of the review.

Summarising and paraphrasing for the critical review

The best way to summarise

• Scan the text. Look for information that can be deduced from the introduction, conclusion, title, and headings. What do these tell you about the main points of the article?
• Locate the topic sentences and highlight the main points as you read.
• Reread the text and make separate notes of the main points. Examples and evidence do not need to be included at this stage. Usually they are used selectively in your critique.

Paraphrasing means putting it into your own words. Paraphrasing offers an alternative to using direct quotations in your summary (and the critique) and can be an efficient way to integrate your summary notes.

The best way to paraphrase

• Review your summary notes
• Rewrite them in your own words and in complete sentences
• Use reporting verbs and phrases, e.g. 'The author describes…', 'Smith argues that …'.
• Use quotation marks if If you include unique or specialist phrases from the text.

Next steps after introduction and literature review

Hi My topic about ''screaning of type2 diabetes mellitus and prediabetes ''What should I do after I finish litreture review in the dessertaion ?

Thanks for your question! Here are some initial thoughts to get the conversation started.

After you finish your literature review, the next step is typically to outline and conduct your research methodology. This section will explain how you plan to carry out your research on screening for type 2 diabetes mellitus and prediabetes. You’ll need to detail the design of your study, the population you’ll be examining, the types of data you’ll collect, and the methods you’ll use to analyze that data.

Key things to consider:

• Research Design: Determine if you’ll use a qualitative, quantitative, or mixed-methods approach.
• Population & Sample: Define the group you’ll be studying and how you’ll select your sample.
• Data Collection: Decide what data you need and how you’ll collect it (e.g., surveys, medical records, interviews).
• Data Analysis: Choose the methods you’ll use to analyze your data, such as statistical tests or thematic analysis.

Once your methodology is solid, you can move on to conducting your research and then writing up your findings.

Best of luck with your project!

S11: MWF at 12–12:50 p.m. in Crothers Engineering Hall 217

Gwen Horsley

English 201 will help students develop skills to write effectively for other university courses, careers, and themselves. This course will provide opportunities to further develop research skills, to write vividly, and to share their own stories and ideas. Specifically, in this class, students will (1) focus on the relationships between world environments, land, animals and humankind; (2) read various essays by environmental, conservational, and regional authors; and (3) produce student writings. Students will improve their writing skills by reading essays and applying techniques they witness in others’ work and those learned in class. This class is also a course in logical and creative thought. Students will write about humankind’s place in the world and our influence on the land and animals, places that hold special meaning to them or have influenced their lives, and stories of their own families and their places and passions in the world. Students will practice writing in an informed and persuasive manner, in language that engages and enlivens readers by using vivid verbs and avoiding unnecessary passives, nominalizations, and expletive constructions.

Students will prepare writing assignments based on readings and discussions of essays included in Literature and the Environment and other sources. They will use The St. Martin’s Handbook to review grammar, punctuation, mechanics, and usage as needed.

Required Text: Literature and the Environment: A Reader On Nature and Culture. 2nd ed., edited by Lorraine Anderson, Scott Slovic, and John P. O’Grady.

LING 203.S01 English Grammar

TuTh 12:30-1:45 p.m.

Dr. Nathan Serfling

The South Dakota State University 2023-2024 Undergraduate Catalog describes LING 203 as consisting of “[i]nstruction in the theory and practice of traditional grammar including the study of parts of speech, parsing, and practical problems in usage.”

“Grammar” is a mercurial term, though. Typically, we think of it to mean “correct” sentence structure, and, indeed, that is one of its meanings. But Merriam-Webster reminds us “grammar” also refers to “the principles or rules of an art, science, or technique,” taking it beyond the confines of syntactic structures. Grammar also evolves in practice through application (and social, historical, economic changes, among others). Furthermore, grammar evolves as a concept as scholars and educators in the various fields of English studies debate the definition and nature of grammar, including how well its explicit instruction improves students’ writing. In this course, we will use the differing sensibilities, definitions, and fluctuations regarding grammar to guide our work. We will examine the parts of speech, address syntactic structures and functions, and parse and diagram sentences. We will also explore definitions of and debates about grammar. All of this will occur in units about the rules and structures of grammar; the application of grammar rhetorically and stylistically; and the debates surrounding various aspects of grammar, including, but not limited to, its instruction.

ENGL 242.S01 American Literature II

TuTh 11 a.m.-12:15 p.m.

Dr. Paul Baggett

This course surveys a range of U.S. literatures from about 1865 to the present, writings that treat the end of slavery and the development of a segregated America, increasingly urbanized and industrialized U.S. landscapes, waves of immigration, and the fulfilled promise of “America” as imperial nation. The class will explore the diversity of identities represented during that time, and the problems/potentials writers imagined in response to the century’s changes—especially literature’s critical power in a time of nation-building. Required texts for the course are The Norton Anthology of American Literature: 1865 to the Present and Toni Morrison’s A Mercy.

WMST 247.S01: Introduction to Women, Gender and Sexuality Studies

As an introduction to Women, Gender and Sexuality studies, this course considers the experiences of women and provides an overview of the history of feminist thought and activism, particularly within the United States. Students will also consider the concepts of gender and sexuality more broadly to encompass a diversity of gender identifications and sexualities and will explore the degree to which mainstream feminism has—and has not—accommodated this diversity. The course will focus in particular on the ways in which gender and sexuality intersect with race, class, ethnicity, and disability. Topics and concepts covered will include: movements for women’s and LGBTQ+ rights; gender, sexuality and the body; intersectionality; rape culture; domestic and gender violence; reproductive rights; Missing and Murdered Indigenous Women (MMIW); and more.

ENGL 283.S01 Introduction to Creative Writing

MWF 1-1:50 p.m.

Prof. Steven Wingate

Students will explore the various forms of creative writing (fiction, nonfiction and poetry) not one at a time in a survey format—as if there were decisive walls of separation between then—but as intensely related genres that share much of their creative DNA. Through close reading and work on personal texts, students will address the decisions that writers in any genre must face on voice, rhetorical position, relationship to audience, etc. Students will produce and revise portfolios of original creative work developed from prompts and research. This course fulfills the same SGR #2 requirements ENGL 201; note that the course will involve creative research projects. Successful completion of ENGL 101 (including by test or dual credit) is a prerequisite.

English 284: Introduction to Criticism

This course introduces students to selected traditions of literary and cultural theory and to some of the key issues that animate discussion among literary scholars today. These include questions about the production of cultural value, about ideology and hegemony, about the patriarchal and colonial bases of Western culture, and about the status of the cultural object, of the cultural critic, and of cultural theory itself.

To address these and other questions, we will survey the history of literary theory and criticism (a history spanning 2500 years) by focusing upon a number of key periods and -isms: Greek and Roman Classicism, The Middle Ages and Renaissance, The Enlightenment, Romanticism, Realism, Formalism, Historicism, Political Criticism (Marxism, Post-Colonialism, Feminism, et al.), and Psychological Criticism. We also will “test” various theories we discuss by examining how well they account for and help us to understand various works of poetry and fiction.

• 300-400 level

ENGL 330.S01 Shakespeare

TuTh 8-9:15 a.m.

Dr. Michael S. Nagy

This course will focus on William Shakespeare’s poetic and dramatic works and on the cultural and social contexts in which he wrote them. In this way, we will gain a greater appreciation of the fact that literature does not exist in a vacuum, for it both reflects and influences contemporary and subsequent cultures. Text: The Riverside Shakespeare: Complete Works. Ed. Evans, G. Blakemore and J. J. M. Tobin. Boston: Houghton Mifflin, 1997.

ENGL 363 Science Fiction

MWF 11-11:50 a.m.

This course explores one of the most significant literary genres of the past century in fiction and in film. We will focus in particular on the relationship between science fiction works and technological and social developments, with considerable attention paid to the role of artificial intelligence in the human imagination. Why does science fiction seem to predict the future? What do readers and writers of the genre hope to find in it? Through readings and viewings of original work, as well as selected criticism in the field, we will address these and other questions. Our reading and viewing selections will include such artists as Ursula K. LeGuin, Octavia Butler, Stanley Kubrick and Phillip K. Dick. Students will also have ample opportunity to introduce the rest of the class to their own favorite science fiction works.

ENGL 383.S01 Creative Writing I

MWF 2-2:50 p.m.

Amber Jensen

Creative Writing I encourages students to strengthen poetry, creative nonfiction, and/or fiction writing skills through sustained focus on creative projects throughout the course (for example, collections of shorter works focused on a particular form/style/theme, longer prose pieces, hybrid works, etc.). Students will engage in small- and large-group writing workshops as well as individual conferences with the instructor throughout the course to develop a portfolio of creative work. The class allows students to explore multiple genres through the processes of writing and revising their own creative texts and through writing workshop, emphasizing the application of craft concepts across genre, but also allows students to choose one genre of emphasis, which they will explore through analysis of self-select texts, which they will use to deepen their understanding of the genre and to contextualize their own creative work.

ENGL 475.S01 Creative Nonfiction

Mondays 3-5:50 p.m.

In this course, students will explore the expansive and exciting genre of creative nonfiction, including a variety of forms such as personal essay, braided essay, flash nonfiction, hermit crab essays, profiles and more. Through rhetorical reading, discussion, and workshop, students will engage published works, their own writing process, and peer work as they expand their understanding of the possibilities presented in this genre and the craft elements that can be used to shape readers’ experience of a text. Students will compile a portfolio of polished work that demonstrates their engagement with course concepts and the writing process.

ENGL 485.S01 Writing Center Tutoring

MW 8:30-9:45 a.m.

Since their beginnings in the 1920s and 30s, writing centers have come to serve numerous functions: as hubs for writing across the curriculum initiatives, sites to develop and deliver workshops, and resource centers for faculty as well as students, among other functions. But the primary function of writing centers has necessarily and rightfully remained the tutoring of student writers. This course will immerse you in that function in two parts. During the first four weeks, you will explore writing center praxis—that is, the dialogic interplay of theory and practice related to writing center work. This part of the course will orient you to writing center history, key theoretical tenets and practical aspects of writing center tutoring. Once we have developed and practiced this foundation, you will begin work in the writing center as a tutor, responsible for assisting a wide variety of student clients with numerous writing tasks. Through this work, you will learn to actively engage with student clients in the revision of a text, respond to different student needs and abilities, work with a variety of writing tasks and rhetorical situations and develop a richer sense of writing as a complex and negotiated social process.

ENGL 492.S01 The Vietnam War in Literature and Film

Tuesdays 3-5:50 p.m.

Dr. Jason McEntee

In 1975, the United States officially included its involvement in the Vietnam War, thus marking 2025 as the 50th anniversary of the conclusion (in name only) of one of the most chaotic, confusing, and complex periods in American history. In this course, we will consider how literature and film attempt to chronicle the Vietnam War and, perhaps more important, its aftermath. I have designed this course for those looking to extend their understanding of literature and film to include the ideas of art, experience, commercial products, and cultural documents. Learning how to interpret literature and movies remains the highest priority of the course, including, for movies, the study of such things as genre, mise-en-scene (camera movement, lighting, etc.), editing, sound and so forth.

We will read Dispatches , A Rumor of War , The Things They Carried , A Piece of My Heart , and Bloods , among others. Some of the movies that we will screen are: Apocalypse Now (the original version), Full Metal Jacket , Platoon , Coming Home , Born on the Fourth of July , Dead Presidents , and Hearts and Minds . Because we must do so, we will also look at some of the more fascinatingly outrageous yet culturally significant fantasies about the war, such as The Green Berets and Rambo: First Blood, Part II .

ENGL 492.S02 Classical Mythology

TuTh 3:30-4:45 p.m.

Drs. Michael S. Nagy and Graham Wrightson

Modern society’s fascination with mythology manifests itself in the continued success of novels, films and television programs about mythological or quasi-mythological characters such as Hercules, the Fisher King, and Gandalf the Grey, all of whom are celebrated for their perseverance or their daring deeds in the face of adversity. This preoccupation with mythological figures necessarily extends back to the cultures which first propagated these myths in early folk tales and poems about such figures as Oðin, King Arthur, Rhiannon, Gilgamesh, and Odysseus, to name just a few. English 492, a reading-intensive course cross-listed with History 492, primarily aims to expose students to the rich tradition of mythological literature written in languages as varied as French, Gaelic, Welsh, Old Icelandic, Greek, and Sumerian; to explore the historical, social, political, religious, and literary contexts in which these works flourished (if indeed they did); and to grapple with the deceptively simple question of what makes these myths continue to resonate with modern audiences. Likely topics and themes of this course will include: Theories of myth; Mythological Beginnings: Creation myths and the fall of man; Male and Female Gods in Myth; Foundation myths; Nature Myths; The Heroic Personality; the mythological portrayal of (evil/disruptive) women in myth; and Monsters in myth.

Secure task offloading and resource allocation strategies in mobile applications using probit mish-gated recurrent unit and an enhanced-searching-based serval optimization algorithm.

1. Introduction

1.1. problem statement.

• Most of the existing works performed task offloading and resource allocation by verifying the task features with the global scheme alone but failed to analyze the local computing features.
• The existing works did not focus on the traffic attributes for load balancing. This resulted in more energy consumption.
• The security of smart contracts was not ensured in the previous works, which lowered the trustworthiness of the networks.
• System consistency is a major challenge for storing hashed information in the cloud computing environment.

1.2. Contributions

• Input: Here, the extracted features are considered as the input. χ r indicates the inputs in the present time frame, and h i d u − 1 indicates the input from the previous hidden state. The inputs proceed to flow via the gates.
• Probit Mish Activation Function: The Probit Mish activation function (PMAF) is employed to improve the learning process and convergence rate. This is formulated as follows:
• Reset Gate: This gate should decide how much irrelevant information needs to be eradicated from the gates. The reset gate ℜ ⊗ is determined as follows:
• Update Gate: The update gate decides how much crucial information needs to be allowed through the gates for further computation. The update gate ℵ ⊕ can be written in a mathematical form as follows:
• Candidate Hidden State: This gate considers the reset gate and determines what relevant information needs to be stored. This is formulated as follows:
• Hidden State: Finally, the hidden state makes a decision about what information needs to be passed through the network as an outcome, and it is defined as follows:

3.2. Secure Resource Allocation in MEC

• Step 1: The number of clusters κ f is specified; then, the centroid point c ψ is randomly initialized by using Equation (21):
• Step 2: During the next part of the derivation, the value of the distance between λ t and c ψ is estimated by using the HCM technique. The HCM technique is used to effectively calculate the distance among the data points. The data points are then assigned to the cluster that has the nearest distance value. This can be expressed as follows:
• Step 3: Finally, the centroid point is recalculated, and the clustering process is repeated until it converges. Thus, the load-balanced requests ρ j υ are given as follows:
• Input features: Here, the task features and cloud features are chosen to perform RA. The task features, such as the number of dimensions, speed, cost, weight, and data size, are extracted. Then, cloud features, such as size, RAM, bandwidth, length, file size, storage, and VM, are also taken into account to allocate the optimal resources. The G -many extracted features β g are initialized as follows:
• Population Initialization: First, the population of the SOA is initialized in the search space. Here, β g is assumed to be the serval. This is structured in the form of a matrix as follows:
• Fitness Function: In this step, the fitness value of β g , k is derived by considering the minimum response time r s t m . This can be estimated by using Equation (28):
• Exploration Phase (prey selection and attack): In this phase, an exploration is carried out according to strategies followed by the serval to perform prey selection and attack. The exploration stage can be briefly described as follows:
• Exploitation Phase (chasing process): After the process of attacking the prey, the exploitation phase takes place based on the chasing strategy of the serval. Here, the entropic linear interpolation (ELI) method is used to update the serval’s position, and its value is defined as follows:
