This was very helpful Jes! Thanks a lot.

We're glad you found this post helpful, Eniale!
Thank you Jes. I found your method to thematic literature review very useful and easy to understand. I am a Phd student in Education with the University of Durban.I am based in Zimbabwe.
We are glad you found this method useful!
I am having difficulties locating an example of a completed literature review outline. Where would I find additional examples? Thank you.
Hello! While we don't have a sample completed literature review for you to look at, you will find partial examples using some of the links here: http://academicguides.waldenu.edu/writingcenter/assignments/literaturereview We offer a few different resources included webinars, podcasts, other blog posts, and more.
You’re welcome!
Hi is literature review writing same as writing a thematic summary after reading articles based on the given topic?
Great question! It depends on the assignment (what faculty want with the thematic summary assignment). For literature reviews, paragraphs revolve around themes within the literature as opposed to authors. So, when Jes uses the phrasing, "thematic literature reviews," she is referring to how literature reviews are about synthesizing themes across the literature as opposed to creating paragraphs that are summaries for each singular author/ source. You can read more about synthesis on our website http://bit.ly/2JEUK09

I'm doing a lit review for a post grad certificate and I have to discuss the findings using a framework analysis, can you lead me to the right section. Yours struggling
Hello, You might check with your professor regarding what is meant by “framework analysis” in relation to the finding of your literature review. While the Writing Center has some sources on components of writing literature reviews, it is best to speak with faculty regarding assignment specifics. You might also check out our page on literature reviews: https://academicguides.waldenu.edu/writingcenter/assignments/literaturereview We hope this helps!
i have found it useful, it has polished me some how, my problem in the literature review is how to formulate themes and subthemes for the topic. forexample dealing with solid waste skips monitoring and management for municpalities. what themes can i build on in the study. thank you dear.

This was very helpful; clear and concise. Thank you!
Oh Jes! you just sent me back to the drawing board, guilty of annotated bibliography. Thank you for this helpful writeup.
I'm sure you're not alone! And there is a reason this is a blog post topic. :) Kudos for identifying potential issues in your own writing and thank you so much for reading and commenting!
im failing to understand the concept themes
This can be a tricky concept to grasp, which is why we've created blog posts like this one. Basically, "themes" are ideas that connect so that writers are organizing based on themes rather than on sources. So instead of having one paragraph about one article, another paragraph about a different article, and a third paragraph about a third article, the paragraphs would be organized based on common ideas shared between two or three of the articles. You might check out our MEAL plan resources (https://academicanswers.waldenu.edu/faq/72800), or our resources for synthesis (https://academicanswers.waldenu.edu/faq/72694) for further clarification. Hope this helps! Thanks for reading!

How to Write a Literature Review: Writing the Review
- How to Write a Literature Review
- What Is a Literature Review
- What Is the Literature
Writing the Review
- See Examples
Why Are You Writing This?
There are two primary points to remember as you are writing your literature review:
- Stand-alone review: provide an overview and analysis of the current state of research on a topic or question
- Research proposal: explicate the current issues and questions concerning a topic to demonstrate how your proposed research will contribute to the field
- Research report: provide the context to which your work is a contribution.
- Write as you read, and revise as you read more. Rather than wait until you have read everything you are planning to review, start writing as soon as you start reading. You will need to reorganize and revise it all later, but writing a summary of an article when you read it helps you to think more carefully about the article. Having drafts and annotations to work with will also make writing the full review easier since you will not have to rely completely on your memory or have to keep thumbing back through all the articles. Your draft does not need to be in finished, or even presentable, form. The first draft is for you, so you can tell yourself what you are thinking. Later you can rewrite it for others to tell them what you think.
General Steps for Writing a Literature Review
Here is a general outline of steps to write a thematically organized literature review. Remember, though, that there are many ways to approach a literature review, depending on its purpose.
- Stage one: annotated bibliography. As you read articles, books, etc, on your topic, write a brief critical synopsis of each. After going through your reading list, you will have an abstract or annotation of each source you read. Later annotations are likely to include more references to other works since you will have your previous readings to compare, but at this point the important goal is to get accurate critical summaries of each individual work.
- Stage two: thematic organization. Find common themes in the works you read, and organize the works into categories. Typically, each work you include in your review can fit into one category or sub-theme of your main theme, but sometimes a work can fit in more than one. (If each work you read can fit into all the categories you list, you probably need to rethink your organization.) Write some brief paragraphs outlining your categories, how in general the works in each category relate to each other, and how the categories relate to each other and to your overall theme.
- Stage three: more reading. Based on the knowledge you have gained in your reading, you should have a better understanding of the topic and of the literature related to it. Perhaps you have discovered specific researchers who are important to the field, or research methodologies you were not aware of. Look for more literature by those authors, on those methodologies, etc. Also, you may be able to set aside some less relevant areas or articles which you pursued initially. Integrate the new readings into your literature review draft. Reorganize themes and read more as appropriate.
- Stage four: write individual sections. For each thematic section, use your draft annotations (it is a good idea to reread the articles and revise annotations, especially the ones you read initially) to write a section which discusses the articles relevant to that theme. Focus your writing on the theme of that section, showing how the articles relate to each other and to the theme, rather than focusing your writing on each individual article. Use the articles as evidence to support your critique of the theme rather than using the theme as an angle to discuss each article individually.
- Stage five: integrate sections. Now that you have the thematic sections, tie them together with an introduction, conclusion, and some additions and revisions in the sections to show how they relate to each other and to your overall theme.
Specific Points to Include
More specifically, here are some points to address when writing about specific works you are reviewing. In dealing with a paper or an argument or theory, you need to assess it (clearly understand and state the claim) and analyze it (evaluate its reliability, usefulness, validity). Look for the following points as you assess and analyze papers, arguments, etc. You do not need to state them all explicitly, but keep them in mind as you write your review:
- Be specific and be succinct. Briefly state specific findings listed in an article, specific methodologies used in a study, or other important points. Literature reviews are not the place for long quotes or in-depth analysis of each point.
- Be selective. You are trying to boil down a lot of information into a small space. Mention just the most important points (i.e. those most relevant to the review's focus) in each work you review.
- Is it a current article? How old is it? Have its claims, evidence, or arguments been superceded by more recent work? If it is not current, is it important for historical background?
- What specific claims are made? Are they stated clearly?
- What evidence, and what type (experimental, statistical, anecdotal, etc) is offered? Is the evidence relevant? sufficient?
- What arguments are given? What assumptions are made, and are they warranted?
- What is the source of the evidence or other information? The author's own experiments, surveys, etc? Historical records? Government documents? How reliable are the sources?
- Does the author take into account contrary or conflicting evidence and arguments? How does the author address disagreements with other researchers?
- What specific conclusions are drawn? Are they warranted by the evidence?
- How does this article, argument, theory, etc, relate to other work?
These, however, are just the points that should be addressed when writing about a specific work. It is not an outline of how to organize your writing. Your overall theme and categories within that theme should organize your writing, and the above points should be integrated into that organization. That is, rather than write something like:
Smith (2009) claims that blah, and provides evidence x to support it, and says it is probably because of blip. But Smith seems to have neglected factor b. Jones (2011) showed that blah by doing y, which, Jones claims, means it is likely because of blot. But that methodology does not exclude other possibilities. Johnson (2012) hypothesizes blah might be because of some other cause.
list the themes and then say how each article relates to that theme. For example:
Researchers agree that blah (Smith 2009, Jones 2011, Johnson 2012), but they do not agree on why. Smith claims it is probably due to blip, but Jones, by doing y, tries to show it is likely because of blot. Jones' methodology, however, does not exclude other possibilities. Johnson hypothesizes ...

Themes and Gaps
Identifying the themes and gaps in the research helps you understand the scholarly conversation around your research topic. This is the purpose of the literature review. Here are some questions to help you examine your articles for themes and gaps.
- What trends do you see in the use of theories, models of understanding, or methodology? How has this changed over time?
- What are the recurring questions or ideas that you see in the articles?
- What are the studies or theories that changed the way scholars understand the topic?
- What are major debates or contradictions? Where do your sources disagree?
- What are the gaps? What is missing? What do we not yet understand? Are there new questions to ask?
Hint! The gaps are important because that is were you'll find room for your research to fit into the conversation.

You are here, identifying themes to structure your literature review.
In order to develop the sections in your literature review you will need to be able to draw out the key themes from your reading. The following questions are designed to help you achieve this:
- What do I already know?
- What are the key concepts and definitions within this area of study?
- What are the political standpoints and historical context?
- What are the beliefs underpinning this area of study?
- Why is it important to study this research problem and how does it relate to the current national/international priorities within education?
- What are the key questions asked by other researchers in this area and how can these help me to develop my own research focus and questions?
- What research strategies and methods have been used by other researchers in this area of study?
- Can I learn from mistakes that have been made by other researchers?
- What are the key theoretical perspectives in this area?
- What are the key research findings?
- How do these existing ideas from theory and research link together?
- How can the literature help me to interpret my findings? E.g. Are there analytical frameworks that have been used by other researchers that I could use to analyse my findings?
- Are there any conflicting research findings or areas of controversy?
- Are there any gaps in the existing research?

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .
There are five key steps to writing a literature review:
- Search for relevant literature
- Evaluate sources
- Identify themes, debates, and gaps
- Outline the structure
- Write your literature review
A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

What is the purpose of a literature review, examples of literature reviews, step 1 – search for relevant literature, step 2 – evaluate and select sources, step 3 – identify themes, debates, and gaps, step 4 – outline your literature review’s structure, step 5 – write your literature review, free lecture slides, frequently asked questions, introduction.
- Quick Run-through
- Step 1 & 2
When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:
- Demonstrate your familiarity with the topic and its scholarly context
- Develop a theoretical framework and methodology for your research
- Position your work in relation to other researchers and theorists
- Show how your research addresses a gap or contributes to a debate
- Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.
Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.
- Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
- Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
- Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
- Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Prevent plagiarism. Run a free check.
Before you begin searching for literature, you need a clearly defined topic .
If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .
Make a list of keywords
Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.
- Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
- Body image, self-perception, self-esteem, mental health
- Generation Z, teenagers, adolescents, youth
Search for relevant sources
Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:
- Your university’s library catalogue
- Google Scholar
- Project Muse (humanities and social sciences)
- Medline (life sciences and biomedicine)
- EconLit (economics)
- Inspec (physics, engineering and computer science)
You can also use boolean operators to help narrow down your search.
Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.
You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.
For each publication, ask yourself:
- What question or problem is the author addressing?
- What are the key concepts and how are they defined?
- What are the key theories, models, and methods?
- Does the research use established frameworks or take an innovative approach?
- What are the results and conclusions of the study?
- How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
- What are the strengths and weaknesses of the research?
Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

Take notes and cite your sources
As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.
It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.
To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:
- Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
- Themes: what questions or concepts recur across the literature?
- Debates, conflicts and contradictions: where do sources disagree?
- Pivotal publications: are there any influential theories or studies that changed the direction of the field?
- Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?
This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.
- Most research has focused on young women.
- There is an increasing interest in the visual aspects of social media.
- But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.
There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).
Chronological
The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.
Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.
If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.
For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.
Methodological
If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:
- Look at what results have emerged in qualitative versus quantitative research
- Discuss how the topic has been approached by empirical versus theoretical scholarship
- Divide the literature into sociological, historical, and cultural sources
Theoretical
A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.
You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.
Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.
The introduction should clearly establish the focus and purpose of the literature review.
Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.
As you write, you can follow these tips:
- Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
- Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
- Critically evaluate: mention the strengths and weaknesses of your sources
- Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts
In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .
It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.
There are several reasons to conduct a literature review at the beginning of a research project:
- To familiarize yourself with the current state of knowledge on your topic
- To ensure that you’re not just repeating what others have already done
- To identify gaps in knowledge and unresolved problems that your research can address
- To develop your theoretical framework and methodology
- To provide an overview of the key findings and debates on the topic
Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.
The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .
A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other academic texts , with an introduction , a main body, and a conclusion .
An annotated bibliography is a list of source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a paper .

Literature Reviews
What this handout is about.
This handout will explain what literature reviews are and offer insights into the form and construction of literature reviews in the humanities, social sciences, and sciences.
Introduction
OK. You’ve got to write a literature review. You dust off a novel and a book of poetry, settle down in your chair, and get ready to issue a “thumbs up” or “thumbs down” as you leaf through the pages. “Literature review” done. Right?
Wrong! The “literature” of a literature review refers to any collection of materials on a topic, not necessarily the great literary texts of the world. “Literature” could be anything from a set of government pamphlets on British colonial methods in Africa to scholarly articles on the treatment of a torn ACL. And a review does not necessarily mean that your reader wants you to give your personal opinion on whether or not you liked these sources.
What is a literature review, then?
A literature review discusses published information in a particular subject area, and sometimes information in a particular subject area within a certain time period.
A literature review can be just a simple summary of the sources, but it usually has an organizational pattern and combines both summary and synthesis. A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information. It might give a new interpretation of old material or combine new with old interpretations. Or it might trace the intellectual progression of the field, including major debates. And depending on the situation, the literature review may evaluate the sources and advise the reader on the most pertinent or relevant.
But how is a literature review different from an academic research paper?
The main focus of an academic research paper is to develop a new argument, and a research paper is likely to contain a literature review as one of its parts. In a research paper, you use the literature as a foundation and as support for a new insight that you contribute. The focus of a literature review, however, is to summarize and synthesize the arguments and ideas of others without adding new contributions.
Why do we write literature reviews?
Literature reviews provide you with a handy guide to a particular topic. If you have limited time to conduct research, literature reviews can give you an overview or act as a stepping stone. For professionals, they are useful reports that keep them up to date with what is current in the field. For scholars, the depth and breadth of the literature review emphasizes the credibility of the writer in his or her field. Literature reviews also provide a solid background for a research paper’s investigation. Comprehensive knowledge of the literature of the field is essential to most research papers.
Who writes these things, anyway?
Literature reviews are written occasionally in the humanities, but mostly in the sciences and social sciences; in experiment and lab reports, they constitute a section of the paper. Sometimes a literature review is written as a paper in itself.
Let’s get to it! What should I do before writing the literature review?
If your assignment is not very specific, seek clarification from your instructor:
- Roughly how many sources should you include?
- What types of sources (books, journal articles, websites)?
- Should you summarize, synthesize, or critique your sources by discussing a common theme or issue?
- Should you evaluate your sources?
- Should you provide subheadings and other background information, such as definitions and/or a history?
Find models
Look for other literature reviews in your area of interest or in the discipline and read them to get a sense of the types of themes you might want to look for in your own research or ways to organize your final review. You can simply put the word “review” in your search engine along with your other topic terms to find articles of this type on the Internet or in an electronic database. The bibliography or reference section of sources you’ve already read are also excellent entry points into your own research.
Narrow your topic
There are hundreds or even thousands of articles and books on most areas of study. The narrower your topic, the easier it will be to limit the number of sources you need to read in order to get a good survey of the material. Your instructor will probably not expect you to read everything that’s out there on the topic, but you’ll make your job easier if you first limit your scope.
Keep in mind that UNC Libraries have research guides and to databases relevant to many fields of study. You can reach out to the subject librarian for a consultation: https://library.unc.edu/support/consultations/ .
And don’t forget to tap into your professor’s (or other professors’) knowledge in the field. Ask your professor questions such as: “If you had to read only one book from the 90’s on topic X, what would it be?” Questions such as this help you to find and determine quickly the most seminal pieces in the field.
Consider whether your sources are current
Some disciplines require that you use information that is as current as possible. In the sciences, for instance, treatments for medical problems are constantly changing according to the latest studies. Information even two years old could be obsolete. However, if you are writing a review in the humanities, history, or social sciences, a survey of the history of the literature may be what is needed, because what is important is how perspectives have changed through the years or within a certain time period. Try sorting through some other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to consider what is currently of interest to scholars in this field and what is not.

Strategies for writing the literature review
Find a focus.
A literature review, like a term paper, is usually organized around ideas, not the sources themselves as an annotated bibliography would be organized. This means that you will not just simply list your sources and go into detail about each one of them, one at a time. No. As you read widely but selectively in your topic area, consider instead what themes or issues connect your sources together. Do they present one or different solutions? Is there an aspect of the field that is missing? How well do they present the material and do they portray it according to an appropriate theory? Do they reveal a trend in the field? A raging debate? Pick one of these themes to focus the organization of your review.
Convey it to your reader
A literature review may not have a traditional thesis statement (one that makes an argument), but you do need to tell readers what to expect. Try writing a simple statement that lets the reader know what is your main organizing principle. Here are a couple of examples:
The current trend in treatment for congestive heart failure combines surgery and medicine. More and more cultural studies scholars are accepting popular media as a subject worthy of academic consideration.
Consider organization
You’ve got a focus, and you’ve stated it clearly and directly. Now what is the most effective way of presenting the information? What are the most important topics, subtopics, etc., that your review needs to include? And in what order should you present them? Develop an organization for your review at both a global and local level:
First, cover the basic categories
Just like most academic papers, literature reviews also must contain at least three basic elements: an introduction or background information section; the body of the review containing the discussion of sources; and, finally, a conclusion and/or recommendations section to end the paper. The following provides a brief description of the content of each:
- Introduction: Gives a quick idea of the topic of the literature review, such as the central theme or organizational pattern.
- Body: Contains your discussion of sources and is organized either chronologically, thematically, or methodologically (see below for more information on each).
- Conclusions/Recommendations: Discuss what you have drawn from reviewing literature so far. Where might the discussion proceed?
Organizing the body
Once you have the basic categories in place, then you must consider how you will present the sources themselves within the body of your paper. Create an organizational method to focus this section even further.
To help you come up with an overall organizational framework for your review, consider the following scenario:
You’ve decided to focus your literature review on materials dealing with sperm whales. This is because you’ve just finished reading Moby Dick, and you wonder if that whale’s portrayal is really real. You start with some articles about the physiology of sperm whales in biology journals written in the 1980’s. But these articles refer to some British biological studies performed on whales in the early 18th century. So you check those out. Then you look up a book written in 1968 with information on how sperm whales have been portrayed in other forms of art, such as in Alaskan poetry, in French painting, or on whale bone, as the whale hunters in the late 19th century used to do. This makes you wonder about American whaling methods during the time portrayed in Moby Dick, so you find some academic articles published in the last five years on how accurately Herman Melville portrayed the whaling scene in his novel.
Now consider some typical ways of organizing the sources into a review:
- Chronological: If your review follows the chronological method, you could write about the materials above according to when they were published. For instance, first you would talk about the British biological studies of the 18th century, then about Moby Dick, published in 1851, then the book on sperm whales in other art (1968), and finally the biology articles (1980s) and the recent articles on American whaling of the 19th century. But there is relatively no continuity among subjects here. And notice that even though the sources on sperm whales in other art and on American whaling are written recently, they are about other subjects/objects that were created much earlier. Thus, the review loses its chronological focus.
- By publication: Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on biological studies of sperm whales if the progression revealed a change in dissection practices of the researchers who wrote and/or conducted the studies.
- By trend: A better way to organize the above sources chronologically is to examine the sources under another trend, such as the history of whaling. Then your review would have subsections according to eras within this period. For instance, the review might examine whaling from pre-1600-1699, 1700-1799, and 1800-1899. Under this method, you would combine the recent studies on American whaling in the 19th century with Moby Dick itself in the 1800-1899 category, even though the authors wrote a century apart.
- Thematic: Thematic reviews of literature are organized around a topic or issue, rather than the progression of time. However, progression of time may still be an important factor in a thematic review. For instance, the sperm whale review could focus on the development of the harpoon for whale hunting. While the study focuses on one topic, harpoon technology, it will still be organized chronologically. The only difference here between a “chronological” and a “thematic” approach is what is emphasized the most: the development of the harpoon or the harpoon technology.But more authentic thematic reviews tend to break away from chronological order. For instance, a thematic review of material on sperm whales might examine how they are portrayed as “evil” in cultural documents. The subsections might include how they are personified, how their proportions are exaggerated, and their behaviors misunderstood. A review organized in this manner would shift between time periods within each section according to the point made.
- Methodological: A methodological approach differs from the two above in that the focusing factor usually does not have to do with the content of the material. Instead, it focuses on the “methods” of the researcher or writer. For the sperm whale project, one methodological approach would be to look at cultural differences between the portrayal of whales in American, British, and French art work. Or the review might focus on the economic impact of whaling on a community. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed. Once you’ve decided on the organizational method for the body of the review, the sections you need to include in the paper should be easy to figure out. They should arise out of your organizational strategy. In other words, a chronological review would have subsections for each vital time period. A thematic review would have subtopics based upon factors that relate to the theme or issue.
Sometimes, though, you might need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. Put in only what is necessary. Here are a few other sections you might want to consider:
- Current Situation: Information necessary to understand the topic or focus of the literature review.
- History: The chronological progression of the field, the literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
- Methods and/or Standards: The criteria you used to select the sources in your literature review or the way in which you present your information. For instance, you might explain that your review includes only peer-reviewed articles and journals.
Questions for Further Research: What questions about the field has the review sparked? How will you further your research as a result of the review?
Begin composing
Once you’ve settled on a general pattern of organization, you’re ready to write each section. There are a few guidelines you should follow during the writing stage as well. Here is a sample paragraph from a literature review about sexism and language to illuminate the following discussion:
However, other studies have shown that even gender-neutral antecedents are more likely to produce masculine images than feminine ones (Gastil, 1990). Hamilton (1988) asked students to complete sentences that required them to fill in pronouns that agreed with gender-neutral antecedents such as “writer,” “pedestrian,” and “persons.” The students were asked to describe any image they had when writing the sentence. Hamilton found that people imagined 3.3 men to each woman in the masculine “generic” condition and 1.5 men per woman in the unbiased condition. Thus, while ambient sexism accounted for some of the masculine bias, sexist language amplified the effect. (Source: Erika Falk and Jordan Mills, “Why Sexist Language Affects Persuasion: The Role of Homophily, Intended Audience, and Offense,” Women and Language19:2).
Use evidence
In the example above, the writers refer to several other sources when making their point. A literature review in this sense is just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence to show that what you are saying is valid.
Be selective
Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the review’s focus, whether it is thematic, methodological, or chronological.
Use quotes sparingly
Falk and Mills do not use any direct quotes. That is because the survey nature of the literature review does not allow for in-depth discussion or detailed quotes from the text. Some short quotes here and there are okay, though, if you want to emphasize a point, or if what the author said just cannot be rewritten in your own words. Notice that Falk and Mills do quote certain terms that were coined by the author, not common knowledge, or taken directly from the study. But if you find yourself wanting to put in more quotes, check with your instructor.
Summarize and synthesize
Remember to summarize and synthesize your sources within each paragraph as well as throughout the review. The authors here recapitulate important features of Hamilton’s study, but then synthesize it by rephrasing the study’s significance and relating it to their own work.
Keep your own voice
While the literature review presents others’ ideas, your voice (the writer’s) should remain front and center. Notice that Falk and Mills weave references to other sources into their own text, but they still maintain their own voice by starting and ending the paragraph with their own ideas and their own words. The sources support what Falk and Mills are saying.
Use caution when paraphrasing
When paraphrasing a source that is not your own, be sure to represent the author’s information or opinions accurately and in your own words. In the preceding example, Falk and Mills either directly refer in the text to the author of their source, such as Hamilton, or they provide ample notation in the text when the ideas they are mentioning are not their own, for example, Gastil’s. For more information, please see our handout on plagiarism .
Revise, revise, revise
Draft in hand? Now you’re ready to revise. Spending a lot of time revising is a wise idea, because your main objective is to present the material, not the argument. So check over your review again to make sure it follows the assignment and/or your outline. Then, just as you would for most other academic forms of writing, rewrite or rework the language of your review so that you’ve presented your information in the most concise manner possible. Be sure to use terminology familiar to your audience; get rid of unnecessary jargon or slang. Finally, double check that you’ve documented your sources and formatted the review appropriately for your discipline.

In the previous article , you looked at how the literature review, wherever it is found, whether in the introduction or in a separate section, might be organised chronologically. Perhaps a more common way to organise the literature review is to group the literature as you see it – that is, to organise and discuss the literature by theme.
Advantages of doing a thematic literature review
- Taking a thematic approach from an early point in your research allows you to see how much literature you have identified for each issue . You can then assess how much more you might need to read.
- Identify which areas may suffer from a significant lack of existing literature/studies .
- Highlight outstanding gaps in the current body of work.
- Demonstrate the need or opportunities for extending previous research.
- Taking this evaluative approach allows you more space to assert your own voice and authority , and to engage more intimately with the literature from the beginning. You’ll get to take a more active role in identifying the connections between existing studies and research on your topic.
- By building connections between themes to your research project, you’ll help your reader gain a better, broader overview of the relevant literature.
Deciding on a thematic literature review
One way to do decide going thematic with your literature review is to categorise your bibliography at an early stage into groups , each of which deals with a particular issue in a similar way.
- So, you might look at a topic by discipline, by epistemology, by theoretical approach or argument or by methodology.
- Alternatively, you might look at the topic by issue or by level (e.g. selecting literature that focuses on individuals at a local / institutional level, rather than national or international).
Note : There are innumerable ways of viewing the literature from a thematic standpoint and there is no one correct method to write or structure a thematic literature review. It is more important to consider what approaches would be more useful to your research project and what would help you to best address your research questions / hypotheses .
Structuring and writing a thematic literature review
Here are some points to keep in mind when organising and writing your literature review thematically.
A. Beginning the review
Reviewing the literature thematically by groups offers you a flexible starting point. Where you begin can impact how you present the rest of the literature.
B. Being evaluative
The thematic approach allows you to identify the strengths and weaknesses of a theme within your specific research. This means that it may be less descriptive than taking a more chronological approach, and would likely be more evaluative or analytical .
C. Establishing your credentials
This review is an important element in establishing your academic credentials, especially at the PhD level. In journal articles , though, you need to keep it as concise as possible, and be selective in choosing the most relevant and appropriate literature to contextualise your specific research.
D. Ending the review
You will probably want to end with the literature closest to your research . The last part may need to go into greater detail if it covers the literature that is the most relevant to your own topic.
Thematic literature review: Example
Below is the first section to an article which clearly breaks up the first part of the literature review into three broad themes (structure, social construction and historical evolution), providing the most prominent names associated with each one. (Note the highlighted text.)
Over the last 20 years, a large number of studies on academic writing have been devoted to the research article, in particular, its structure, social construction and historical evolution. A number of these studies have concerned themselves with the overall organization of various parts of the research article , such as the introduction (e.g. Swales, 1981, Swales, 1990, Swales and Najjar, 1987), the results sections (Brett, 1994, Thompson, 1993), discussions (Hopkins & Dudley-Evans, 1988) and even the abstracts that accompany the research articles (Salager-Meyer, 1990, Salager-Meyer, 1992). Various lexico-grammatical features of the research article (RA) have also been explored, ranging from tense choice to citation practices. Beyond the textual structure of this genre, research has also focused on the historical development of the research article (Bazerman, 1988, Atkinson, 1993, Salager-Meyer, 1999, Vande Kopple, 1998) and the social construction of this genre (Myers, 1990).

Common themes in American literature include the great journey, the loss of innocence, the great battle, love and friendship, and revenge. The theme of a book is the underlying meaning within the story.
In literature, a theme is a common thread or main idea that is repeated throughout a literary work. The theme of a novel or story is the major message that organizes the entire work.
Although there are an infinite combination of topics for themes, there are two basic types of themes in literature: major and minor. A major theme is the central message of a story.
