why is writing a literature review such hard work? part one

But this post is not about any of these important and essential literature processes. No, this post is about the knowledge work that underpins the processes, knowledge work that makes your literature review successful, or not.

The literature “review”, as it is called, is not simply about reading and sorting and then writing. It’s not really a “review” per se. It’s critical evaluation, categorisation, and synthesis. And using writing to help. And then constructing the text. Authoring. This is all about thinking – and writing. And thinking and writing are not two distinct things.

In literatures work, writing and thinking are inseparable. Just as it’s hard to separate out the colours in a marble cake, it’s the same with thinking-writing about literatures. Thinking and writing are melded.

When you work with literatures and write your “review”, you are doing very difficult conceptual and authoring work – you are extending and consolidating at least six domains of knowledge. Yes, six. They are:

• Substantive knowledge from your discipline, or disciplines . This is sometimes called subject or content knowledge and it refers to the actual topic of your research – history, physics, psychology, geography and so on. When you read, you are building on what you already know about your subject, reflecting critically on it, adding to it, and perhaps reframing the ways in which you think about it. Knowledge about your discipline also means learning its language, the very specific terminology that is used to shorthand concepts. Knowing your discipline may also require you to learn particular ways to write – see (3).
• Knowledge about your readers – supervisors and examiners – and the scholarly community that they belong to. Disciplines have particular ways of explaining what they do, have been, and are, to themselves and others. There are key texts, writers and moments which are generally taken as important. Your readers are familiar with these texts, people and events, and they expect that you will be too.
• Knowledge about the kind of text that you are writing – often called genre. You are expected to follow the conventions of writing about, and with literatures to suit the genre you are working in – a paper, report or thesis. The conventions may be shaped in part by your discipline – see (1). But in essence the literatures “review” is where you locate your study in its field. You aren’t writing a long book review or an essay showing everything you know. It’s usually an argument.
• Knowledge about the kind of rhetoric that you have to use. Rhetorical knowledge is not the same as knowing about grammar, it is a given that your work has to be grammatically correct and your citations accurate. Knowing about rhetoric means understanding the ways in which language is used to construct an argument for your  work, through explaining the work of others. There are some traps here, the most common is writing a laundry list . A long listicle of your reading is problematic because lacks the kind of meta-commentary that is needed to guide the reader through your interpretation of the field, and the texts most relevant to your research. You have to know how to write without laundry-listing.
• Knowledge about the process of writing . Writing process knowledge is built up over time, as you develop your own set of strategies to diagnose issues with your texts, and to revise and edit. You build up a set of strategies that work for you, as well as a set of criteria that you can use to judge the quality of your own work. You come to understand that writing a thesis or paper may also very well involve un-learning some processes that have up till now, worked OK.
• Knowledge about scholarship and you as a schola r. Writing about and with literatures is part and parcel of forming an identity as a scholar – you make yourself as this or that kind of researcher through who you cite and how you write about them. But you also build your understandings of the ways in which the academy functions, and take up an ethical stance, through writing yourself in relation to the work of others. And you develop a writing “voice”.

So it’s no wonder that writing a literatures “review” is so tricky. There’s a lot going on. You are learning, using what you already know and authoring at the same time. This is complex work which can’t be rushed.

And understanding what’s involved, what you need to know, the six domains you’re working with, can be helpful.

Part Two, on why literatures reviews are hard, looks at locational work. That’s coming next week.

The literature review is an essential component of academic research writing, providing a comprehensive overview of existing research and informing the development of new studies. However, writing an effective literature review can be a challenging task for many authors, particularly those new to academic writing. This chapter aims to guide authors through the process of writing a literature review by highlighting common mistakes and best practices. The chapter begins with three short narratives that describe difficulties both novice and prolific authors encounter when writing the literature review. A chapter activity follows with steps that guide authors through the process of developing a research question to frame the literature review. Authors are then prompted to complete a self-assessment activity which includes a series of questions designed to build their skills as academic research writers. The body of the chapter recommends strategies and techniques to help authors locate and evaluate sources that will serve as the building blocks for a literature review that is thorough, current, and well-written. The chapter concludes with a discussion of the threats and benefits of artificial intelligence-based text production in relationship to academic research writing. Overall, this chapter provides practical guidance for authors looking to improve their literature review writing skills and enhance the quality of their research output.

Issue: AI-Based Text Production in Academic Research Writing

 Artificial Intelligence (AI) is a relatively new technological development that can be used to support academic research writing, particularly reviews of research. Although it holds promise as a research tool, there are also concerns that AI-based scholarly writing could threaten not only the integrity but also the creativity of academic research writing. ChatGPT, an advanced chatbot developed by OpenAI (a nonprofit research company founded by Elon Musk and Sam Altman in 2015) has been at the center of much controversy as of late because of its ability to produce academic papers using artificial intelligence-based text production that have fooled academics and academic journal publishers (Hern, 2022 ; Lucey & Dowling, 2023 ; TechTarget, 2023 ). To demonstrate ChatGPT’s capabilities, consider its response to the question, “What is artificial intelligence-based text production?”.

Artificial Intelligence-Based Text Production is a process where machine learning algorithms are used to generate written content such as articles, product descriptions, social media posts, and more. It involves training machine learning models with vast amounts of data to learn how to generate human-like text automatically. The process can involve different techniques such as Natural Language Processing (NLP), deep learning, and neural networks to analyze and understand language patterns, grammar, context, and semantics. The resulting AI-generated text can be used for a wide range of applications, including content marketing, chatbots, language translation, and more. One of the main benefits of AI-based text production is that it can help businesses and organizations automate their content creation process, saving time and resources while producing high-quality content. However, it is important to note that AI-generated text may not always be perfect and may require human editing and review to ensure accuracy and coherence.

This response was produced by ChatGPT in about ten seconds. According to Anson ( 2022 ), “cutting and pasting all or part of this auto-generated text into a new text box can continue to prompt further content. The material is not plagiarized from existing sources but freshly composed. For this reason, it usually evades plagiarism-detection programs like Turnitin” (p. 40).

How Might AI-Based Text Production Threaten Academic Research Writing?

Obviously, computer-generated text that evades plagiarism-detection programs threatens the integrity of academic research writing. Some academic publishers have already banned or limited the use of AI-generated text in papers submitted to their journals (Lucey & Dowling, 2023 ). However, that is easier said than done. OpenAI recently developed a tool that attempts to distinguish between human-written and AI-generated text to prevent chatbots like ChatGPT from being abused, but it is only 26% effective (Wiggers, 2023 ).

Lucey and Dowling ( 2023 ) tested the credibility of ChatGPT by having expert reviewers examine papers produced by the chatbot. First, they asked ChatGPT to generate four parts of a research study: (1) research idea, (2) literature review, (3) dataset, and (4) suggestions for testing and examination. They chose a broad subject and instructed the chatbot to create a paper that could be published in “a good finance journal” (para. 6). Second, they pasted 200 relevant abstracts into the ChatGPT search box and asked the chatbot to consider the abstracts when generating the four-part research study. Finally, they asked academic researchers to read both versions of the AI-generated text and make suggestions for improvement. A panel of thirty-two reviewers read all versions of the four-part research study and rated them. In all cases, the papers were considered acceptable by the reviewers, although the chatbot-created papers that also included input from academic researchers were rated higher. However, “a chatbot was deemed capable of generating quality academic research ideas. This raises fundamental questions around the meaning of creativity and ownership of creative ideas—questions to which nobody yet has solid answers” (Lucey & Dowling, 2023 , para. 10).

How Might AI-Based Text Production Benefit Academic Research Writing?

Despite several publishers deciding to ban the inclusion of AI-based text production in submissions, some researchers have already listed ChatGPT as a co-author on their papers (Lucey & Dowling, 2023 ). There are many who believe there is no difference between the way ChatGPT produces text and the way authors synthesize studies in their literature reviews. In fact, the chatbot’s review is much more exhaustive because it can analyze “billions of existing, human-produced texts and, through a process akin to the creation of neural networks, generate new text based on highly complex predictive machine analysis” (Anson, 2022 , p. 39).

There are other advantages to using AI-based text production. It has the potential to aid groups of researchers who lack funding to hire human research assistants such as emerging economy researchers, graduate students, and early career researchers. According to Lucey and Dowling ( 2023 ), AI-based text production “could help democratize the research process” (para. 18). Anson ( 2022 ) also sees the potential in AI-based text production to “spark some new human-generated ideas” (p. 42), extract keywords, and create abstracts. The development of AI-based text production might also force instructors to change the way they teach academic writing. Instead of trying to detect or prevent the use of chatbots like ChatGPT, “a more sensible approach could involve embracing the technology, showing students what it can and can’t do, and asking them to experiment with it” (Anson, 2022 , p. 44). In other words, students could be asked to write about writing which leads to a deeper understanding of the writing process and the ability to transfer that understanding to any writing project (Wardle & Downs, 2019 ).

The Responsible Use of AI-Based Text Production in Academic Research Writing

The responsible use of AI-based text production in academic research writing involves understanding the technology's capabilities and limitations, as well as considering its potential impact on the research process. Researchers must carefully evaluate the intended purpose and context of using AI-generated text and make certain they are not compromising the authenticity and integrity of their research work. To ensure responsible use, it is essential to balance the benefits of increased efficiency and new insights with the need for originality and critical thinking in academic research writing. Researchers must also be transparent in disclosing the use of AI-generated text when submitting their work for publication. By adopting a responsible and thoughtful approach to the use of AI-based text production, researchers can maximize the benefits of the technology while maintaining the quality and authenticity of their research.

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

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

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

• Example : Employment Instability and Fertility in Europe: A Meta-Analysis:  10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts .  Journal of Advanced Nursing , 53 (3), 311-318.

• Example : Women’s perspectives on career successes and barriers: A qualitative meta-synthesis:  10.1177/05390184221113735

Planning Your Literature Review

Defining your research question, questions to ask, books about literature reviews.

• Searching Tips
• Getting Materials
• Scholarly Information
• Managing Your Results
• Writing Your Review

Writing a literature review will take time to gather and analyze the research relevant to your topic, so it best to start early and give yourself enough time to gather and analyze your sources.  The process of writing a literature review usually covers the following steps:

• Define your Research question
• Plan your approach to your research and your review
• Search the Literature
• Analyze the material you’ve found
• Managing the results of your research
• Writing your Review

One of the hardest parts of a literature review is to develop a good research question.  You don't want a research question that is so broad it encompasses too many research areas, and can't be reasonably answered. 

Defining your topic may require an initial review of literature on your topic to get a sense of the scope about your topic.   Select a topic of interest, and do a preliminary search to see what kinds of research is being done and what is trending in that topic area.  This will give you a better sense of the topic, and help you focus your research question

In specifying your topic or research question, you should think about setting appropriate limitations on the research you are seeking. Limiting, for example, by time, personnel, gender, age, location, nationality etc. results in a more focused and meaningful topic. 

Using an example from the Duke University Writing Studio, you may start with a general question: 

Why did the chicken cross the road ?  This question is so general that you could be gathering relevant research for days. 

A more precise research question might be: 

What are some of the environmental factors that occurred in Pittsburgh, PA between January and February 2015 that would cause a chicken to cross Forbes Avenue?   This research question is specific about a number of variables like time, geography, etc.

Some questions to think about as you develop your literature review:

• What is known about the subject?
• Are there any gaps in the knowledge of the subject?
• Have areas of further study been identified by other researchers that you may want to consider?
• Who are the significant research personalities in this area?
• Is there consensus about the topic?
• What aspects have generated significant debate on the topic?
• What methods or problems were identified by others studying in the field and how might they impact your research?
• What is the most productive methodology for your research based on the literature you have reviewed?
• What is the current status of research in this area?
• What sources of information or data were identified that might be useful to you?
• How detailed? Will it be a review of ALL relevant material or will the scope be limited to more recent material, e.g., the last five years.
• Are you focusing on methodological approaches; on theoretical issues; on qualitative or quantitative research?

Besides the obvious reason for students -- because it is assigned! -- a literature review helps you explore the research that has come before you, to see how your research question has (or has not) already been addressed.

You identify:

• core research in the field
• experts in the subject area
• methodology you may want to use (or avoid)
• gaps in knowledge -- or where your research would fit in

The Graduate Writing Guy :: Writing Tips for Grad School

Literature reviews

Writing literature reviews (or “reviews of literature” if you’re “not into the whole brevity thing ”) is one of the more challenging academic tasks you’ll have to face as a grad student. If you’re writing a thesis or dissertation, for example, the lit review chapter (usually chapter 2) might be the hardest chapter to write, perhaps rivaled only by the “discussion” chapter. And even then, part of what makes the discussion chapter difficult is that it has to integrate your own findings (or data) with the main conclusions from your lit review (I should acknowledge that my claims here apply mainly to the sciences and social sciences, since humanities papers don’t always have such clearly-defined sections).

One problem that makes lit reviews difficult to write is simply students’ lack of preparation. In my experience, many professors teaching at the undergrad level assume that, if you go to grad school, you’ll be taught how to write lit reviews there. At the same time, many professors at the grad level assume that you were already taught how to write lit reviews at the undergrad level. Obviously, this gap creates confusion, especially for students.  

Another problem is that experts (like professors) often underestimate how difficult a task will be for a beginner (see, for example, this study , this study , and this study ). So, even if your professors know that writing literature reviews is a new challenge for you, they might not be aware of just how difficult the process will be (or how much scaffolding you might need).

All of this is to say: if you’re having trouble with writing a literature review for a thesis, dissertation, seminar paper, or journal article, there’s nothing wrong with you. Writing literature reviews is difficult. Having trouble doesn’t mean that you’re stupid or incapable. You just need a little guidance. And that’s why you’re visiting this page.

This page offers some of the best advice, suggestions, and materials I have to offer regarding lit reviews.

Video: Lit Reviews “Crash Course” (16 min)

This video is a brief overview for people in a hurry. It goes over the basic idea of what a literature review is and gives an “orientation” to the most useful resources posted on this page. You can view the video by clicking here (opens in a new window). Note: The “ice cream” lit review document is supposed to be visible onscreen starting around 6:33 in the video, but for some reason it doesn’t appear. So I recommend downloading that document in the “Handouts” section below and following along.

Also, David Taylor, “your online writing professor,” has a nice video called “How to Write a Literature Review in 30 Minutes or Less,” which you can watch below:

However, make sure to pay close attention to what he says about re-ordering paragraphs into a logical list–what I like to call “telling a story” (the “story” he tells is about defining a problem, showing that it’s widespread, presenting solutions, etc.). And make sure to follow his advice about adding topic sentences and transition sentences. I add these cautions because, if you don’t pay attention, some of his advice could be misunderstood as suggesting that you can just paste in your annotated bibliography and add in a few transitions, and then, voila! You have a literature review. But that is not what he is saying, and doing that will not get you a very good grade in a graduate class.

Video: 2021 Workshop on Lit Reviews (78 min)

You can view or download a recording of my workshop on literature reviews (from March 11, 2021) here or by clicking on the image below:

Note 2: The video covers a whole range of topics, including what lit reviews are, how to find literature, how to read the literature, and so on. The part that discusses actually writing & structuring the lit review starts at approximately 52 minutes (52:48, to be exact).

Below are my PowerPoint slides from the workshop:

1 . The “Ice Cream Lit Review” is a slightly silly handout I put together to acquaint students with some basic ideas about structuring lit reviews. Note that this review is organized around a debate in the field.

2. The “Zombie” lit review is another silly handout. This review is based around themes (or subtopics) that emerge from the literature (so it’s a useful model for lit reviews organized around subtopics).

3. Also, at my workshops I’ve often shared the following handout from the Azusa Pacific University Writing Center which includes a sample mini lit review:

While this mini lit review is much shorter than almost any lit review you’re likely to write in grad school, students often find it helpful to see, in highly abbreviated form, what a lit review is supposed to accomplish.

4. Useful links and transition words . This one is relevant to academic writing in general, but students who are working on lit reviews often ask me about transition words, so it’s a good handout to include here:

Sample Lit Reviews

There is no single, universal “right way” to write a literature review. What counts as a good lit review depends a lot on your discipline, your professor/advisor, or what specific journal you’re submitting to. So, the best way to familiarize yourself with what kind of lit review you’re expected to write is to look at examples from your field, your campus, or your intended journal.

One helpful approach is to browse theses or dissertations written by recently-graduated students in your discipline. If you’re a CSULB grad student, you can do so by logging onto your single sign-on . Click on the “University Library” button and, after the Library page loads, select the “Services” drop-down menu at the top of the page and scroll down to “Thesis and Dissertation.” Click on “Thesis and Dissertation.” When the Thesis Office page loads, click on the gray “Find a Thesis or Dissertation” on the bottom left side of the page (or try this direct link ).

The Purdue Online Writing Lab (OWL ) has a nice sample literature review with comments:

Note, however, that this is a somewhat short and basic literature review (possibly from an undergraduate paper). So, while it’s a good introductory model, the lit reviews you’ll have to write in grad school will likely be longer and more complex.

However, Purdue OWL also has some great general advice on writing literature reviews. I highly recommend the OWL’s tutorials.

Dr. Kimberly Rombach has posted an excellent “Example of a Lit Review” online . Below is a PDF version that includes some commentary by me on the first 10 pages.

The University of LaVerne has some great sample lit reviews (and tutorials) posted on the Literature Review Basics page maintained by librarian Liberty McCoy. What’s great about the samples here is that they’re all peer-reviewed articles and organized by discipline.

The APA also has a nice sample lit review that you can download here ( Note: This is one of those direct download links that automatically downloads a Word doc).

When reading samples, you can maximize your learning by “ reading like a writer ,” as discussed by Mike Bunn. Pay attention to choices made by the authors of the samples, and think about what these choices accomplish and whether or not your paper could benefit from similar choices. Such choices can include:

–What kind (or how many) headers to include

–Uses of transitions and signal words to convey arguments clearly to readers

–How many authors are cited per section

–How many sources to include overall

–How much detail (and what kinds of detail) are discussed for each source mentioned

–How sources are “integrated” or “synthesized” together; how much the sources “talk to each other” (see further comments in “Synthesizing and Integrating Sources” below).

Developing a Research Question

A lot of the students I work with at CSULB start working on a preliminary literature review for their thesis or dissertation even before they’ve firmly narrowed down an exact research question. That is, they start the thesis-writing process by putting together a rough draft of the literature review based on a topic (rather than a question), or on a somewhat vague question (that they’ll “polish” later). This is perfectly fine. But the final draft of your literature review will likely have been re-written so that it addresses the scholarly conversation on a specific question or set of closely-related questions. In any case, if you’re having trouble with research questions, the following resources can help:

Wendy Belcher: Solution to Writing Obstacle No. 26: “I have to read just one more book before I can write.”

Summarizing and Paraphrasing Sources

In addition to the problem of structuring the whole lit review, some students struggle with summarizing articles (which is a necessary part of most lit reviews). How does one distill a 20-page journal article, for instance, into a 1-2 paragraph summary?

In the humanities (e.g. literature, philosophy), you might simply summarize the main points of an author’s argument. For example, you might realize that the argument proceeds in major “steps” or “moves,” so you might summarize each major step/move in a sentence or two. For example:

In his paper on the ethics of bank robbing, R. Hood (1954) argues that it is ethically permissible to rob banks as long as the funds are re-distributed to the poor. He defends this claim on utilitarian grounds, noting that the total happiness of the society will increase by an amount far greater than the relatively minor decrease in happiness experienced by the banks’ shareholders. He considers, then refutes, objections to this position, including objections based on non-utilitarian approaches to ethics (egoism, Kantian deontology).

For the physical and social sciences (or any “ empirical ” area of study), on the other hand, research articles almost always include a standard list of specific elements (listed below), whether or not each of these elements has its own heading or subheading in the article. Most, if not all, of these elements should be paraphrased in your summary.

These elements are:

–Purpose: What was the purpose of the study? What were the researchers trying to accomplish or figure out? For example : “This study aimed to assess the prevalence of depression and its associated factors among medical students.”

–Research questions: What exact/specific question(s) did the researchers try to answer? For example: “What is the prevalence of depression among a random sample of medical students in Karnataka, India? In this sample, what associations exist between depression and the following social factors: alcohol use, drug addiction, family problems, family history of depression, and staying away from home?”

–Methods: What type of study was it ( qualitative, quantitative, or mixed methods )? What did they do exactly? ( specific tools or instruments used ) Who were the participants/what was the sample? How were they selected? What were their demographics ? (obviously, these questions will be different depending on whether the study was conducted on people, animals, or inanimate objects)? For example : “This study used quantitative methods. A stratified random sample of 400 students (54.3% males and 45.7% females) was assessed using the Beck Depression Inventory. Univariate analysis was conducted to test for associations between depression and the selected variables (social factors).”

–Findings/results: What did the researchers find out? Did they confirm or disconfirm (refute) any existing studies/findings? For example: “The overall prevalence of depression was found to be 71.25%. Among those with depression, a majority (80%) had mild and moderate depression. The study showed that 46.3% (132) of the depressed were females and 53.7% (153) were males. The prevalence of depression was found to be significantly greater among those with family problems and family history of depression.”

–Limitations & delimitations: To crudely oversimplify, limitations are potential weaknesses or blind spots of your study that are outside of your control (based on the fundamental limits of your particular method). For example : “One limitation of this study was that the Back Depression Inventory relies on self-reporting of symptoms, and self-report depends on the assumption that participants accurately report their thoughts and feelings.” Delimitations are potential weaknesses or blind spots that are inside your control. For example: “Because the researchers studied participants from only one region of India, the results may not be universalizable to other contexts.” For more on limitations and delimitations, see this helpful article from Dissertation Recipes .

–Significance: Why should we care about the findings? How are they important to the field? How does this study contribute to your argument? How will the findings of this study inform your research? For example : “The study showed that depression is highly prevalent among medical students in the area studied. The findings point to the importance of broad screening and psychiatric counseling of this vulnerable population.”

The examples above are based on this study:

Kumar, G. S., Animesh, J., & Hegde, S. (2012). Prevalence of depression and its associated factors using Beck Depression Inventory among students of a medical college in Karnataka. Indian Journal of Psychiatry , 54 (3), 223–226. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3512357/

A few notes of caution:

–By using this study as an example, I am not necessarily attesting to the quality of the research or the writing (I’m not a medical professional – who am I to judge?). I am simply using it because it was easy to locate, and it clearly and directly lists most of the elements discussed above.

–To save time, I indiscriminately plagiarized some of the exact wording used in the published  study. DO NOT DO THIS in your class papers. It is an unethical action for which your professors will not grade you kindly!

–The order of items in your summary does not have to follow the order that I’ve used above.

–As stated elsewhere on this page, not all summaries in a lit review will include all of the elements I’ve listed above. These are just given as examples. Remember that, in your actual lit review, you will only include detailed summaries of a small number of articles. You will not summarize most of the literature in great detail—most of the time you’ll be simply reporting major findings, along with synthesizing and integrating your sources.  

For more information on proper paraphrases and avoiding plagiarism , see my page on Avoiding Plagiarism . See also the following made-up example to give you some idea of what a completed summary might look like:

Bokanovsky and Seldin (2017) studied the psycho-social challenges facing gender and sexual minority (GSM) youth in urban schools. Their purpose was to look for correlations between depression and experiences of bullying among the target population. The sample included 100 young people from inner city schools in the Southwestern US who self-identified as belonging to a gender or sexual minority. The researchers used a mixed methods approach, administering the Beck Depression inventory (a quantitative tool) and a series of open-ended interview questions (qualitative) to all participants. They found that there was a strong correlation between bullying and experiences of depression, and that this correlation was especially pronounced among transgender participants. This study underscores the high risk of both bullying and depression among GSM youth, and points to the need for further study of this topic.

Further resources : Summarizing articles for a lit review is very similar to writing a “precis” or an abstract (although these terms have specific meanings depending on the discipline and/or the professor who’s teaching you). So, the following resources might be helpful:

Synthesizing and Integrating Sources

Professors often complain that students write their literature reviews as a long string of summaries: “First, Author A (2015) states X. He used Y methods and had Z many participants. He found that…

Second, Author B (2019) states that… She used X methods to…. She concluded that…”

Generally speaking, this is NOT what professors want you to do. Instead, they want you to “synthesize” (or “integrate”) the literature, meaning that you organize your literature review around key ideas (or themes), and incorporate the authors/sources into this discussion. In other words, your discussion is idea-driven (or topic-driven) rather than paper-driven.

For example, a “synthesized” literature review might include sentences like this one: “There are many schools of thought on topic X. The principal schools of thought are Y, Z, and T… One of the principal contemporary defenders of the Y position is Author A (2015), who argues that…”

This is just an example, of course. There are many different ways to structure a literature review, including arranging it chronologically (e.g. showing the historical evolution of ideas on a topic), arranging it by key positions or schools of thought in a debate (like the example given a few lines above, and like the “ice cream” lit review handout available on this page), arranging it “top-down” (e.g. a major “umbrella” topic which is divided into several subtopics), or arranging it according to some theoretical framework that you’re applying to understand the topic. Finally, many lit reviews are simply organized around “themes” that emerge from the literature. In other words, you read several articles (i.e., literature) focused on a particular topic. Five of these articles all mentioned some key idea, or subtopic, that plays an important role in the main topic. This key idea could be a “theme” that you’ll talk about in your lit review. In addition, 12 of the articles mentioned another key idea. This could be another theme. Your literature review will start with something like: “This literature review examines studies on topic X. Three key themes emerge from this examination: (1) Theme a, (2) Theme b,” and so on. See the “Zombie” lit review handout above for a model of a theme-based literature review.

Your topic, research questions, and purpose will ultimately determine what the right organizational approach is. But the right approach is pretty much NEVER going to be: “just list a series of papers, in whatever order, and summarize them one by one.” Instead, you should choose an organizational approach that best suits your topic (and any arguments or claims you make about it).

Another way to synthesize is to get papers to “talk to each other.” For example, “Johnson (2011) finds that Y is the case. His study involved a sample size of… ” (here, you’re briefly summarizing the main findings, methods, etc. of Johnson, 2011). Now, you’re going to make the Johnson paper “talk to” another paper: “In contrast, Tanizaki (2015) conducts a similar study, but has strikingly different findings from Johnson….” (now, you elaborate on Tanizaki’s study and explain the differences from Johnson’s). Finally, the synthesis: “Taken together, these studies demonstrate the need for further research on Y. For example, it is unclear whether…”

With these points in mind, here are some useful materials on “synthesizing” information in your lit review:

Many students find it helpful to make a “synthesis matrix” to record the main ideas of the articles that they’ve read. You can find helpful examples here and here , or download this sample handed out by some professors in our CSULB Education department:

Critiquing Sources

Most literature reviews are expected to include some critiques of the literature that’s being reviewed. Critiques can be made of several papers or articles at once (i.e., you can critique a body of work on a topic) or of single papers (i.e., you can “zoom in” on a particular article, usually an especially important or groundbreaking article, and summarize it, as described above, and then critique it).

Here’s an example of an author critiquing several articles at once (in this case, the specific type of critique is pointing out “gaps” in the literature):

These examples are from pp. 173-174 of Galvan, J. L. & Galvan, M. C. (2017). Writing literature reviews: A guide for students of the social and behavioral sciences (7th ed.). Routledge.

Here’s another example of critiquing more than one article in the same passage (this example is form p. 217 of the same Galvan and Galvan text cited above; here the critique is about sample size):

Here’s an example of “zooming in” on a study (technically, two studies, but the structure would be the same for one study) and then providing a specific critique (this example is from p. 205 of Galvan):

When critiquing research, it can be helpful to ask questions such as (the following are adapted from this page by Dr. Ali Rezaei ):

• Is the significance of the problem discussed?
• If necessary, are variables directly or operationally defined?
• Is instrument validity discussed and coefficients given if appropriate?
• Is reliability discussed in terms of type and size of reliability coefficients?
• If an instrument was developed specifically for the study, are the procedures involved in its development and validation described?
• Is the design appropriate for answering the questions or testing the hypotheses of the study?
• Are the procedures described in sufficient detail to permit them to be replicated by another researcher?
• If a pilot study was conducted, are its execution and results described as well as its impact on the subsequent study?
• Are the control procedures described?
• Did the researcher discuss or account for any potentially confounding variables that he or she was unable to control for?

The above are just some examples and don’t cover all the possibilities.

The following handout collects some excerpts from Galvan and Galvan (2017) that offer useful tips on writing critiques of research literature:

How To Structure Your Literature Review

3 options to help structure your chapter.

By: Amy Rommelspacher (PhD) | Reviewer: Dr Eunice Rautenbach | November 2020 (Updated May 2023)

Writing the literature review chapter can seem pretty daunting when you’re piecing together your dissertation or thesis. As  we’ve discussed before , a good literature review needs to achieve a few very important objectives – it should:

• Demonstrate your knowledge of the research topic
• Identify the gaps in the literature and show how your research links to these
• Provide the foundation for your conceptual framework (if you have one)
• Inform your own  methodology and research design

To achieve this, your literature review needs a well-thought-out structure . Get the structure of your literature review chapter wrong and you’ll struggle to achieve these objectives. Don’t worry though – in this post, we’ll look at how to structure your literature review for maximum impact (and marks!).

But wait – is this the right time?

Deciding on the structure of your literature review should come towards the end of the literature review process – after you have collected and digested the literature, but before you start writing the chapter. 

In other words, you need to first develop a rich understanding of the literature before you even attempt to map out a structure. There’s no use trying to develop a structure before you’ve fully wrapped your head around the existing research.

Equally importantly, you need to have a structure in place before you start writing , or your literature review will most likely end up a rambling, disjointed mess. 

Importantly, don’t feel that once you’ve defined a structure you can’t iterate on it. It’s perfectly natural to adjust as you engage in the writing process. As we’ve discussed before , writing is a way of developing your thinking, so it’s quite common for your thinking to change – and therefore, for your chapter structure to change – as you write. 

Need a helping hand?

Like any other chapter in your thesis or dissertation, your literature review needs to have a clear, logical structure. At a minimum, it should have three essential components – an  introduction , a  body   and a  conclusion . 

Let’s take a closer look at each of these.

1: The Introduction Section

Just like any good introduction, the introduction section of your literature review should introduce the purpose and layout (organisation) of the chapter. In other words, your introduction needs to give the reader a taste of what’s to come, and how you’re going to lay that out. Essentially, you should provide the reader with a high-level roadmap of your chapter to give them a taste of the journey that lies ahead.

Here’s an example of the layout visualised in a literature review introduction:

Your introduction should also outline your topic (including any tricky terminology or jargon) and provide an explanation of the scope of your literature review – in other words, what you  will   and  won’t   be covering (the delimitations ). This helps ringfence your review and achieve a clear focus . The clearer and narrower your focus, the deeper you can dive into the topic (which is typically where the magic lies). 

Depending on the nature of your project, you could also present your stance or point of view at this stage. In other words, after grappling with the literature you’ll have an opinion about what the trends and concerns are in the field as well as what’s lacking. The introduction section can then present these ideas so that it is clear to examiners that you’re aware of how your research connects with existing knowledge .

2: The Body Section

The body of your literature review is the centre of your work. This is where you’ll present, analyse, evaluate and synthesise the existing research. In other words, this is where you’re going to earn (or lose) the most marks. Therefore, it’s important to carefully think about how you will organise your discussion to present it in a clear way. 

The body of your literature review should do just as the description of this chapter suggests. It should “review” the literature – in other words, identify, analyse, and synthesise it. So, when thinking about structuring your literature review, you need to think about which structural approach will provide the best “review” for your specific type of research and objectives (we’ll get to this shortly).

There are (broadly speaking)  three options  for organising your literature review.

Option 1: Chronological (according to date)

Organising the literature chronologically is one of the simplest ways to structure your literature review. You start with what was published first and work your way through the literature until you reach the work published most recently. Pretty straightforward.

The benefit of this option is that it makes it easy to discuss the developments and debates in the field as they emerged over time. Organising your literature chronologically also allows you to highlight how specific articles or pieces of work might have changed the course of the field – in other words, which research has had the most impact . Therefore, this approach is very useful when your research is aimed at understanding how the topic has unfolded over time and is often used by scholars in the field of history. That said, this approach can be utilised by anyone that wants to explore change over time .

For example , if a student of politics is investigating how the understanding of democracy has evolved over time, they could use the chronological approach to provide a narrative that demonstrates how this understanding has changed through the ages.

Here are some questions you can ask yourself to help you structure your literature review chronologically.

• What is the earliest literature published relating to this topic?
• How has the field changed over time? Why?
• What are the most recent discoveries/theories?

In some ways, chronology plays a part whichever way you decide to structure your literature review, because you will always, to a certain extent, be analysing how the literature has developed. However, with the chronological approach, the emphasis is very firmly on how the discussion has evolved over time , as opposed to how all the literature links together (which we’ll discuss next ).

Option 2: Thematic (grouped by theme)

The thematic approach to structuring a literature review means organising your literature by theme or category – for example, by independent variables (i.e. factors that have an impact on a specific outcome).

As you’ve been collecting and synthesising literature , you’ll likely have started seeing some themes or patterns emerging. You can then use these themes or patterns as a structure for your body discussion. The thematic approach is the most common approach and is useful for structuring literature reviews in most fields.

For example, if you were researching which factors contributed towards people trusting an organisation, you might find themes such as consumers’ perceptions of an organisation’s competence, benevolence and integrity. Structuring your literature review thematically would mean structuring your literature review’s body section to discuss each of these themes, one section at a time.

Here are some questions to ask yourself when structuring your literature review by themes:

• Are there any patterns that have come to light in the literature?
• What are the central themes and categories used by the researchers?
• Do I have enough evidence of these themes?

PS – you can see an example of a thematically structured literature review in our literature review sample walkthrough video here.

Option 3: Methodological

The methodological option is a way of structuring your literature review by the research methodologies used . In other words, organising your discussion based on the angle from which each piece of research was approached – for example, qualitative , quantitative or mixed  methodologies.

Structuring your literature review by methodology can be useful if you are drawing research from a variety of disciplines and are critiquing different methodologies. The point of this approach is to question  how  existing research has been conducted, as opposed to  what  the conclusions and/or findings the research were.

For example, a sociologist might centre their research around critiquing specific fieldwork practices. Their literature review will then be a summary of the fieldwork methodologies used by different studies.

Here are some questions you can ask yourself when structuring your literature review according to methodology:

• Which methodologies have been utilised in this field?
• Which methodology is the most popular (and why)?
• What are the strengths and weaknesses of the various methodologies?
• How can the existing methodologies inform my own methodology?

3: The Conclusion Section

Once you’ve completed the body section of your literature review using one of the structural approaches we discussed above, you’ll need to “wrap up” your literature review and pull all the pieces together to set the direction for the rest of your dissertation or thesis.

The conclusion is where you’ll present the key findings of your literature review. In this section, you should emphasise the research that is especially important to your research questions and highlight the gaps that exist in the literature. Based on this, you need to make it clear what you will add to the literature – in other words, justify your own research by showing how it will help fill one or more of the gaps you just identified.

Last but not least, if it’s your intention to develop a conceptual framework for your dissertation or thesis, the conclusion section is a good place to present this.

Example: Thematically Structured Review

In the video below, we unpack a literature review chapter so that you can see an example of a thematically structure review in practice.

Let’s Recap

In this article, we’ve  discussed how to structure your literature review for maximum impact. Here’s a quick recap of what  you need to keep in mind when deciding on your literature review structure:

• Just like other chapters, your literature review needs a clear introduction , body and conclusion .
• The introduction section should provide an overview of what you will discuss in your literature review.
• The body section of your literature review can be organised by chronology , theme or methodology . The right structural approach depends on what you’re trying to achieve with your research.
• The conclusion section should draw together the key findings of your literature review and link them to your research questions.

What is a literature review?

A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.

What is the purpose of literature review?

A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2  

1. Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge. 

2. Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field.

3. Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research. 

4. Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 

5. Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 

6. Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

a. Habitat Loss and Species Extinction:

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

b. Range Shifts and Phenological Changes:

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

c. Ocean Acidification and Coral Reefs:

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

d. Adaptive Strategies and Conservation Efforts:

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

Conducting a literature review

Conducting a literature review is an essential step in research that involves reviewing and analyzing existing literature on a specific topic. It’s important to know how to do a literature review effectively, so here are the steps to follow: 1  

Choose a Topic and Define the Research Question:

• Select a topic that is relevant to your field of study. 
• Clearly define your research question or objective. Determine what specific aspect of the topic do you want to explore? 

Decide on the Scope of Your Review:

• Determine the timeframe for your literature review. Are you focusing on recent developments, or do you want a historical overview? 
• Consider the geographical scope. Is your review global, or are you focusing on a specific region? 
• Define the inclusion and exclusion criteria. What types of sources will you include? Are there specific types of studies or publications you will exclude? 

Select Databases for Searches:

• Identify relevant databases for your field. Examples include PubMed, IEEE Xplore, Scopus, Web of Science, and Google Scholar. 
• Consider searching in library catalogs, institutional repositories, and specialized databases related to your topic. 

Conduct Searches and Keep Track:

• Develop a systematic search strategy using keywords, Boolean operators (AND, OR, NOT), and other search techniques. 
• Record and document your search strategy for transparency and replicability. 
• Keep track of the articles, including publication details, abstracts, and links. Use citation management tools like EndNote, Zotero, or Mendeley to organize your references. 

Review the Literature:

• Evaluate the relevance and quality of each source. Consider the methodology, sample size, and results of studies. 
• Organize the literature by themes or key concepts. Identify patterns, trends, and gaps in the existing research. 
• Summarize key findings and arguments from each source. Compare and contrast different perspectives. 
• Identify areas where there is a consensus in the literature and where there are conflicting opinions. 
• Provide critical analysis and synthesis of the literature. What are the strengths and weaknesses of existing research? 

Organize and Write Your Literature Review:

• Literature review outline should be based on themes, chronological order, or methodological approaches. 
• Write a clear and coherent narrative that synthesizes the information gathered. 
• Use proper citations for each source and ensure consistency in your citation style (APA, MLA, Chicago, etc.). 
• Conclude your literature review by summarizing key findings, identifying gaps, and suggesting areas for future research.

Frequently asked questions

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic.

A sophisticated literature review (LR) can result in a robust dissertation/thesis by scrutinizing the main problem examined by the academic study; anticipating research hypotheses, methods and results; and maintaining the interest of the audience in how the dissertation/thesis will provide solutions for the current gaps in a particular field. Unfortunately, little guidance is available on elaborating LRs, and writing an LR chapter is not a linear process. An LR translates students’ abilities in information literacy, the language domain, and critical writing. Students in postgraduate programs should be systematically trained in these skills. Therefore, this paper discusses the purposes of LRs in dissertations and theses. Second, the paper considers five steps for developing a review: defining the main topic, searching the literature, analyzing the results, writing the review and reflecting on the writing. Ultimately, this study proposes a twelve-item LR checklist. By clearly stating the desired achievements, this checklist allows Masters and Ph.D. students to continuously assess their own progress in elaborating an LR. Institutions aiming to strengthen students’ necessary skills in critical academic writing should also use this tool.

INTRODUCTION

Writing the literature review (LR) is often viewed as a difficult task that can be a point of writer’s block and procrastination ( 1 ) in postgraduate life. Disagreements on the definitions or classifications of LRs ( 2 ) may confuse students about their purpose and scope, as well as how to perform an LR. Interestingly, at many universities, the LR is still an important element in any academic work, despite the more recent trend of producing scientific articles rather than classical theses.

The LR is not an isolated section of the thesis/dissertation or a copy of the background section of a research proposal. It identifies the state-of-the-art knowledge in a particular field, clarifies information that is already known, elucidates implications of the problem being analyzed, links theory and practice ( 3 - 5 ), highlights gaps in the current literature, and places the dissertation/thesis within the research agenda of that field. Additionally, by writing the LR, postgraduate students will comprehend the structure of the subject and elaborate on their cognitive connections ( 3 ) while analyzing and synthesizing data with increasing maturity.

At the same time, the LR transforms the student and hints at the contents of other chapters for the reader. First, the LR explains the research question; second, it supports the hypothesis, objectives, and methods of the research project; and finally, it facilitates a description of the student’s interpretation of the results and his/her conclusions. For scholars, the LR is an introductory chapter ( 6 ). If it is well written, it demonstrates the student’s understanding of and maturity in a particular topic. A sound and sophisticated LR can indicate a robust dissertation/thesis.

A consensus on the best method to elaborate a dissertation/thesis has not been achieved. The LR can be a distinct chapter or included in different sections; it can be part of the introduction chapter, part of each research topic, or part of each published paper ( 7 ). However, scholars view the LR as an integral part of the main body of an academic work because it is intrinsically connected to other sections ( Figure 1 ) and is frequently present. The structure of the LR depends on the conventions of a particular discipline, the rules of the department, and the student’s and supervisor’s areas of expertise, needs and interests.

Interestingly, many postgraduate students choose to submit their LR to peer-reviewed journals. As LRs are critical evaluations of current knowledge, they are indeed publishable material, even in the form of narrative or systematic reviews. However, systematic reviews have specific patterns 1 ( 8 ) that may not entirely fit with the questions posed in the dissertation/thesis. Additionally, the scope of a systematic review may be too narrow, and the strict criteria for study inclusion may omit important information from the dissertation/thesis. Therefore, this essay discusses the definition of an LR is and methods to develop an LR in the context of an academic dissertation/thesis. Finally, we suggest a checklist to evaluate an LR.

WHAT IS A LITERATURE REVIEW IN A THESIS?

Conducting research and writing a dissertation/thesis translates rational thinking and enthusiasm ( 9 ). While a strong body of literature that instructs students on research methodology, data analysis and writing scientific papers exists, little guidance on performing LRs is available. The LR is a unique opportunity to assess and contrast various arguments and theories, not just summarize them. The research results should not be discussed within the LR, but the postgraduate student tends to write a comprehensive LR while reflecting on his or her own findings ( 10 ).

Many people believe that writing an LR is a lonely and linear process. Supervisors or the institutions assume that the Ph.D. student has mastered the relevant techniques and vocabulary associated with his/her subject and conducts a self-reflection about previously published findings. Indeed, while elaborating the LR, the student should aggregate diverse skills, which mainly rely on his/her own commitment to mastering them. Thus, less supervision should be required ( 11 ). However, the parameters described above might not currently be the case for many students ( 11 , 12 ), and the lack of formal and systematic training on writing LRs is an important concern ( 11 ).

An institutional environment devoted to active learning will provide students the opportunity to continuously reflect on LRs, which will form a dialogue between the postgraduate student and the current literature in a particular field ( 13 ). Postgraduate students will be interpreting studies by other researchers, and, according to Hart (1998) ( 3 ), the outcomes of the LR in a dissertation/thesis include the following:

• To identify what research has been performed and what topics require further investigation in a particular field of knowledge;
• To determine the context of the problem;
• To recognize the main methodologies and techniques that have been used in the past;
• To place the current research project within the historical, methodological and theoretical context of a particular field;
• To identify significant aspects of the topic;
• To elucidate the implications of the topic;
• To offer an alternative perspective;
• To discern how the studied subject is structured;
• To improve the student’s subject vocabulary in a particular field; and
• To characterize the links between theory and practice.

A sound LR translates the postgraduate student’s expertise in academic and scientific writing: it expresses his/her level of comfort with synthesizing ideas ( 11 ). The LR reveals how well the postgraduate student has proceeded in three domains: an effective literature search, the language domain, and critical writing.

Effective literature search

All students should be trained in gathering appropriate data for specific purposes, and information literacy skills are a cornerstone. These skills are defined as “an individual’s ability to know when they need information, to identify information that can help them address the issue or problem at hand, and to locate, evaluate, and use that information effectively” ( 14 ). Librarian support is of vital importance in coaching the appropriate use of Boolean logic (AND, OR, NOT) and other tools for highly efficient literature searches (e.g., quotation marks and truncation), as is the appropriate management of electronic databases.

Language domain

Academic writing must be concise and precise: unnecessary words distract the reader from the essential content ( 15 ). In this context, reading about issues distant from the research topic ( 16 ) may increase students’ general vocabulary and familiarity with grammar. Ultimately, reading diverse materials facilitates and encourages the writing process itself.

Critical writing

Critical judgment includes critical reading, thinking and writing. It supposes a student’s analytical reflection about what he/she has read. The student should delineate the basic elements of the topic, characterize the most relevant claims, identify relationships, and finally contrast those relationships ( 17 ). Each scientific document highlights the perspective of the author, and students will become more confident in judging the supporting evidence and underlying premises of a study and constructing their own counterargument as they read more articles. A paucity of integration or contradictory perspectives indicates lower levels of cognitive complexity ( 12 ).

Thus, while elaborating an LR, the postgraduate student should achieve the highest category of Bloom’s cognitive skills: evaluation ( 12 ). The writer should not only summarize data and understand each topic but also be able to make judgments based on objective criteria, compare resources and findings, identify discrepancies due to methodology, and construct his/her own argument ( 12 ). As a result, the student will be sufficiently confident to show his/her own voice .

Writing a consistent LR is an intense and complex activity that reveals the training and long-lasting academic skills of a writer. It is not a lonely or linear process. However, students are unlikely to be prepared to write an LR if they have not mastered the aforementioned domains ( 10 ). An institutional environment that supports student learning is crucial.

Different institutions employ distinct methods to promote students’ learning processes. First, many universities propose modules to develop behind the scenes activities that enhance self-reflection about general skills (e.g., the skills we have mastered and the skills we need to develop further), behaviors that should be incorporated (e.g., self-criticism about one’s own thoughts), and each student’s role in the advancement of his/her field. Lectures or workshops about LRs themselves are useful because they describe the purposes of the LR and how it fits into the whole picture of a student’s work. These activities may explain what type of discussion an LR must involve, the importance of defining the correct scope, the reasons to include a particular resource, and the main role of critical reading.

Some pedagogic services that promote a continuous improvement in study and academic skills are equally important. Examples include workshops about time management, the accomplishment of personal objectives, active learning, and foreign languages for nonnative speakers. Additionally, opportunities to converse with other students promotes an awareness of others’ experiences and difficulties. Ultimately, the supervisor’s role in providing feedback and setting deadlines is crucial in developing students’ abilities and in strengthening students’ writing quality ( 12 ).

HOW SHOULD A LITERATURE REVIEW BE DEVELOPED?

A consensus on the appropriate method for elaborating an LR is not available, but four main steps are generally accepted: defining the main topic, searching the literature, analyzing the results, and writing ( 6 ). We suggest a fifth step: reflecting on the information that has been written in previous publications ( Figure 2 ).

First step: Defining the main topic

Planning an LR is directly linked to the research main question of the thesis and occurs in parallel to students’ training in the three domains discussed above. The planning stage helps organize ideas, delimit the scope of the LR ( 11 ), and avoid the wasting of time in the process. Planning includes the following steps:

• Reflecting on the scope of the LR: postgraduate students will have assumptions about what material must be addressed and what information is not essential to an LR ( 13 , 18 ). Cooper’s Taxonomy of Literature Reviews 2 systematizes the writing process through six characteristics and nonmutually exclusive categories. The focus refers to the reviewer’s most important points of interest, while the goals concern what students want to achieve with the LR. The perspective assumes answers to the student’s own view of the LR and how he/she presents a particular issue. The coverage defines how comprehensive the student is in presenting the literature, and the organization determines the sequence of arguments. The audience is defined as the group for whom the LR is written.
• Designating sections and subsections: Headings and subheadings should be specific, explanatory and have a coherent sequence throughout the text ( 4 ). They simulate an inverted pyramid, with an increasing level of reflection and depth of argument.
• Identifying keywords: The relevant keywords for each LR section should be listed to guide the literature search. This list should mirror what Hart (1998) ( 3 ) advocates as subject vocabulary . The keywords will also be useful when the student is writing the LR since they guide the reader through the text.
• Delineating the time interval and language of documents to be retrieved in the second step. The most recently published documents should be considered, but relevant texts published before a predefined cutoff year can be included if they are classic documents in that field. Extra care should be employed when translating documents.

Second step: Searching the literature

The ability to gather adequate information from the literature must be addressed in postgraduate programs. Librarian support is important, particularly for accessing difficult texts. This step comprises the following components:

• Searching the literature itself: This process consists of defining which databases (electronic or dissertation/thesis repositories), official documents, and books will be searched and then actively conducting the search. Information literacy skills have a central role in this stage. While searching electronic databases, controlled vocabulary (e.g., Medical Subject Headings, or MeSH, for the PubMed database) or specific standardized syntax rules may need to be applied.

In addition, two other approaches are suggested. First, a review of the reference list of each document might be useful for identifying relevant publications to be included and important opinions to be assessed. This step is also relevant for referencing the original studies and leading authors in that field. Moreover, students can directly contact the experts on a particular topic to consult with them regarding their experience or use them as a source of additional unpublished documents.

Before submitting a dissertation/thesis, the electronic search strategy should be repeated. This process will ensure that the most recently published papers will be considered in the LR.

• Selecting documents for inclusion: Generally, the most recent literature will be included in the form of published peer-reviewed papers. Assess books and unpublished material, such as conference abstracts, academic texts and government reports, are also important to assess since the gray literature also offers valuable information. However, since these materials are not peer-reviewed, we recommend that they are carefully added to the LR.

This task is an important exercise in time management. First, students should read the title and abstract to understand whether that document suits their purposes, addresses the research question, and helps develop the topic of interest. Then, they should scan the full text, determine how it is structured, group it with similar documents, and verify whether other arguments might be considered ( 5 ).

Third step: Analyzing the results

Critical reading and thinking skills are important in this step. This step consists of the following components:

• Reading documents: The student may read various texts in depth according to LR sections and subsections ( defining the main topic ), which is not a passive activity ( 1 ). Some questions should be asked to practice critical analysis skills, as listed below. Is the research question evident and articulated with previous knowledge? What are the authors’ research goals and theoretical orientations, and how do they interact? Are the authors’ claims related to other scholars’ research? Do the authors consider different perspectives? Was the research project designed and conducted properly? Are the results and discussion plausible, and are they consistent with the research objectives and methodology? What are the strengths and limitations of this work? How do the authors support their findings? How does this work contribute to the current research topic? ( 1 , 19 )
• Taking notes: Students who systematically take notes on each document are more readily able to establish similarities or differences with other documents and to highlight personal observations. This approach reinforces the student’s ideas about the next step and helps develop his/her own academic voice ( 1 , 13 ). Voice recognition software ( 16 ), mind maps ( 5 ), flowcharts, tables, spreadsheets, personal comments on the referenced texts, and note-taking apps are all available tools for managing these observations, and the student him/herself should use the tool that best improves his/her learning. Additionally, when a student is considering submitting an LR to a peer-reviewed journal, notes should be taken on the activities performed in all five steps to ensure that they are able to be replicated.

Fourth step: Writing

The recognition of when a student is able and ready to write after a sufficient period of reading and thinking is likely a difficult task. Some students can produce a review in a single long work session. However, as discussed above, writing is not a linear process, and students do not need to write LRs according to a specific sequence of sections. Writing an LR is a time-consuming task, and some scholars believe that a period of at least six months is sufficient ( 6 ). An LR, and academic writing in general, expresses the writer’s proper thoughts, conclusions about others’ work ( 6 , 10 , 13 , 16 ), and decisions about methods to progress in the chosen field of knowledge. Thus, each student is expected to present a different learning and writing trajectory.

In this step, writing methods should be considered; then, editing, citing and correct referencing should complete this stage, at least temporarily. Freewriting techniques may be a good starting point for brainstorming ideas and improving the understanding of the information that has been read ( 1 ). Students should consider the following parameters when creating an agenda for writing the LR: two-hour writing blocks (at minimum), with prespecified tasks that are possible to complete in one section; short (minutes) and long breaks (days or weeks) to allow sufficient time for mental rest and reflection; and short- and long-term goals to motivate the writing itself ( 20 ). With increasing experience, this scheme can vary widely, and it is not a straightforward rule. Importantly, each discipline has a different way of writing ( 1 ), and each department has its own preferred styles for citations and references.

Fifth step: Reflecting on the writing

In this step, the postgraduate student should ask him/herself the same questions as in the analyzing the results step, which can take more time than anticipated. Ambiguities, repeated ideas, and a lack of coherence may not be noted when the student is immersed in the writing task for long periods. The whole effort will likely be a work in progress, and continuous refinements in the written material will occur once the writing process has begun.

LITERATURE REVIEW CHECKLIST

In contrast to review papers, the LR of a dissertation/thesis should not be a standalone piece or work. Instead, it should present the student as a scholar and should maintain the interest of the audience in how that dissertation/thesis will provide solutions for the current gaps in a particular field.

A checklist for evaluating an LR is convenient for students’ continuous academic development and research transparency: it clearly states the desired achievements for the LR of a dissertation/thesis. Here, we present an LR checklist developed from an LR scoring rubric ( 11 ). For a critical analysis of an LR, we maintain the five categories but offer twelve criteria that are not scaled ( Figure 3 ). The criteria all have the same importance and are not mutually exclusive.

First category: Coverage

1. justified criteria exist for the inclusion and exclusion of literature in the review.

This criterion builds on the main topic and areas covered by the LR ( 18 ). While experts may be confident in retrieving and selecting literature, postgraduate students must convince their audience about the adequacy of their search strategy and their reasons for intentionally selecting what material to cover ( 11 ). References from different fields of knowledge provide distinct perspective, but narrowing the scope of coverage may be important in areas with a large body of existing knowledge.

Second category: Synthesis

2. a critical examination of the state of the field exists.

A critical examination is an assessment of distinct aspects in the field ( 1 ) along with a constructive argument. It is not a negative critique but an expression of the student’s understanding of how other scholars have added to the topic ( 1 ), and the student should analyze and contextualize contradictory statements. A writer’s personal bias (beliefs or political involvement) have been shown to influence the structure and writing of a document; therefore, the cultural and paradigmatic background guide how the theories are revised and presented ( 13 ). However, an honest judgment is important when considering different perspectives.

3. The topic or problem is clearly placed in the context of the broader scholarly literature

The broader scholarly literature should be related to the chosen main topic for the LR ( how to develop the literature review section). The LR can cover the literature from one or more disciplines, depending on its scope, but it should always offer a new perspective. In addition, students should be careful in citing and referencing previous publications. As a rule, original studies and primary references should generally be included. Systematic and narrative reviews present summarized data, and it may be important to cite them, particularly for issues that should be understood but do not require a detailed description. Similarly, quotations highlight the exact statement from another publication. However, excessive referencing may disclose lower levels of analysis and synthesis by the student.

4. The LR is critically placed in the historical context of the field

Situating the LR in its historical context shows the level of comfort of the student in addressing a particular topic. Instead of only presenting statements and theories in a temporal approach, which occasionally follows a linear timeline, the LR should authentically characterize the student’s academic work in the state-of-art techniques in their particular field of knowledge. Thus, the LR should reinforce why the dissertation/thesis represents original work in the chosen research field.

5. Ambiguities in definitions are considered and resolved

Distinct theories on the same topic may exist in different disciplines, and one discipline may consider multiple concepts to explain one topic. These misunderstandings should be addressed and contemplated. The LR should not synthesize all theories or concepts at the same time. Although this approach might demonstrate in-depth reading on a particular topic, it can reveal a student’s inability to comprehend and synthesize his/her research problem.

6. Important variables and phenomena relevant to the topic are articulated

The LR is a unique opportunity to articulate ideas and arguments and to purpose new relationships between them ( 10 , 11 ). More importantly, a sound LR will outline to the audience how these important variables and phenomena will be addressed in the current academic work. Indeed, the LR should build a bidirectional link with the remaining sections and ground the connections between all of the sections ( Figure 1 ).

7. A synthesized new perspective on the literature has been established

The LR is a ‘creative inquiry’ ( 13 ) in which the student elaborates his/her own discourse, builds on previous knowledge in the field, and describes his/her own perspective while interpreting others’ work ( 13 , 17 ). Thus, students should articulate the current knowledge, not accept the results at face value ( 11 , 13 , 17 ), and improve their own cognitive abilities ( 12 ).

Third category: Methodology

8. the main methodologies and research techniques that have been used in the field are identified and their advantages and disadvantages are discussed.

The LR is expected to distinguish the research that has been completed from investigations that remain to be performed, address the benefits and limitations of the main methods applied to date, and consider the strategies for addressing the expected limitations described above. While placing his/her research within the methodological context of a particular topic, the LR will justify the methodology of the study and substantiate the student’s interpretations.

9. Ideas and theories in the field are related to research methodologies

The audience expects the writer to analyze and synthesize methodological approaches in the field. The findings should be explained according to the strengths and limitations of previous research methods, and students must avoid interpretations that are not supported by the analyzed literature. This criterion translates to the student’s comprehension of the applicability and types of answers provided by different research methodologies, even those using a quantitative or qualitative research approach.

Fourth category: Significance

10. the scholarly significance of the research problem is rationalized.

The LR is an introductory section of a dissertation/thesis and will present the postgraduate student as a scholar in a particular field ( 11 ). Therefore, the LR should discuss how the research problem is currently addressed in the discipline being investigated or in different disciplines, depending on the scope of the LR. The LR explains the academic paradigms in the topic of interest ( 13 ) and methods to advance the field from these starting points. However, an excess number of personal citations—whether referencing the student’s research or studies by his/her research team—may reflect a narrow literature search and a lack of comprehensive synthesis of ideas and arguments.

11. The practical significance of the research problem is rationalized

The practical significance indicates a student’s comprehensive understanding of research terminology (e.g., risk versus associated factor), methodology (e.g., efficacy versus effectiveness) and plausible interpretations in the context of the field. Notably, the academic argument about a topic may not always reflect the debate in real life terms. For example, using a quantitative approach in epidemiology, statistically significant differences between groups do not explain all of the factors involved in a particular problem ( 21 ). Therefore, excessive faith in p -values may reflect lower levels of critical evaluation of the context and implications of a research problem by the student.

Fifth category: Rhetoric

12. the lr was written with a coherent, clear structure that supported the review.

This category strictly relates to the language domain: the text should be coherent and presented in a logical sequence, regardless of which organizational ( 18 ) approach is chosen. The beginning of each section/subsection should state what themes will be addressed, paragraphs should be carefully linked to each other ( 10 ), and the first sentence of each paragraph should generally summarize the content. Additionally, the student’s statements are clear, sound, and linked to other scholars’ works, and precise and concise language that follows standardized writing conventions (e.g., in terms of active/passive voice and verb tenses) is used. Attention to grammar, such as orthography and punctuation, indicates prudence and supports a robust dissertation/thesis. Ultimately, all of these strategies provide fluency and consistency for the text.

Although the scoring rubric was initially proposed for postgraduate programs in education research, we are convinced that this checklist is a valuable tool for all academic areas. It enables the monitoring of students’ learning curves and a concentrated effort on any criteria that are not yet achieved. For institutions, the checklist is a guide to support supervisors’ feedback, improve students’ writing skills, and highlight the learning goals of each program. These criteria do not form a linear sequence, but ideally, all twelve achievements should be perceived in the LR.

CONCLUSIONS

A single correct method to classify, evaluate and guide the elaboration of an LR has not been established. In this essay, we have suggested directions for planning, structuring and critically evaluating an LR. The planning of the scope of an LR and approaches to complete it is a valuable effort, and the five steps represent a rational starting point. An institutional environment devoted to active learning will support students in continuously reflecting on LRs, which will form a dialogue between the writer and the current literature in a particular field ( 13 ).

The completion of an LR is a challenging and necessary process for understanding one’s own field of expertise. Knowledge is always transitory, but our responsibility as scholars is to provide a critical contribution to our field, allowing others to think through our work. Good researchers are grounded in sophisticated LRs, which reveal a writer’s training and long-lasting academic skills. We recommend using the LR checklist as a tool for strengthening the skills necessary for critical academic writing.

2 In 1988, Cooper proposed a taxonomy that aims to facilitate students’ and institutions’ understanding of literature reviews. Six characteristics with specific categories are briefly described: Focus: research outcomes, research methodologies, theories, or practices and applications; Goals: integration (generalization, conflict resolution, and linguistic bridge-building), criticism, or identification of central issues; Perspective: neutral representation or espousal of a position; Coverage: exhaustive, exhaustive with selective citations, representative, central or pivotal; Organization: historical, conceptual, or methodological; and Audience: specialized scholars, general scholars, practitioners or policymakers, or the general public.
