📖 What Is a Literature Review?

- Explains all sides of the argument.
- Evaluates the research findings and their quality.
🎯 What Is the Purpose of a Literature Review?
When answering what the purpose of a literature review is, one needs to remember a few objectives of a literature review:
- It identifies and narrows down the problem you are studying.
- It synthesizes the information from your literature survey into a summary.
- It presents the literature in an organized way.

✍️ How to Write a Literature Review
Now that you are familiar with the elements, it’s time to figure out how to write a literature review for a research paper.
Below, you will find a list of useful tips to ease your studies. And don’t forget to check out valuable links at the end of the article!
Check the Format
Before you start your paper, you need to get acquainted with the required citation style guidelines to format your literature review correctly. Here are several reasons why you need to do this first:
- To recognize the author(s) of the materials you’re using in your research.
- To give context to your study and show that your paper is properly researched.
- To enable your readers to find the sources for more detailed information if needed.
- To allow for further research by informing others about what has already been studied on a given topic.
Be sure to cite other authors’ ideas and words whenever you:
- Make a summary.
- Quote directly.
- Use relatively unknown facts.
- Incorporate evidence that directly relates to your argument.
Choose a Topic
Selecting the right topic for your literature review is a vital step towards writing an effective paper.
The best tips for the issue are as follows:
- Look for a topic that you find interesting. The right choice will make the researching and writing process more pleasurable and rewarding in the end.
- Brainstorm your ideas. Try this method to make your ideas flow more freely. Keep refining your ideas until you find something that will pique your curiosity.
- Skim through the sources. You won’t write a literature review on this topic correctly if it hasn’t been researched by others yet. Make sure that there is enough related literature available for your review.
- Make it neither too general nor too specific. Too broad of a topic will spread your and your readers’ attention thin, and it will be challenging to study. Too narrow of an idea might be detrimental for a literature review, meaning one might not have enough supporting articles. However, if you find enough studies on a specific idea, that would be ideal.
Find Core Materials
By now, you have defined the topic and scope of your literature review. Your next step is to start identifying specific resources. Thorough academic research will undoubtedly take some time.
The good news is this:
Once it’s done the way it should be, the research almost writes the literature review for you.
Here are some tips:
Write down any keywords that describe your topic. Use a reference tool or a thesaurus to generate this list. Then use these keywords to research scholarly databases. These search terms will help you find useful sources.
Choosing incorrect or non-descriptive keywords will return results that are too shallow.
Here are some suggestions for online multidisciplinary databases that you might use:
Evaluate the Sources
Before deciding whether you should include the material you’ve found, you should engage in a critical literature evaluation.
Some of the materials retrieved from the Internet may end up not being credible or not valuable enough for your project. Peer-reviewed journals are more likely to be scientifically valid.
You can use this table as a checklist for evaluating your sources:
Analyze the Websites
Before you use or cite any information you find on a website, you should carefully evaluate the source in a few ways:
- Search for information about the author: “About Us,” “About This Site,” etc.
- Make sure you can reach the website’s author/webmaster by e-mail or some other means.
- Assess the authority of the URL (site’s web address).
Pay special attention to top-level domains:
– .com – most likely a commercial site (maybe selling products or services).
– .edu – an educational institution (mostly reliable, but still may be a personal web page of an institution’s member).
– .gov – highly reliable, representing a government department or agent.
– .net – network access provider.
– .org – a non-profit organization (reliability level may vary).
Make a Summary
The summaries of your findings in the format of a table or concept map will help you review, manage, and summarize the literature you’ve dug up.
- If you use tables for your review, they must include an analysis to summarize, explain, and synthesize the material that you’re reviewing.
What’s the best way to create tables?
You can use Microsoft Word’s table functionality, or you can create the table in Excel first and then copy→paste/import the completed Excel sheet into Word. Using Excel will let you incorporate some useful functions like sorting your findings (e.g., by date, by author, by method, and then by date, etc.)
- As a starting point, try organizing the following data for your literature review into tables or maps:
- Keywords and concepts.
- Points of view.
- Facts and statistics.
- Research methods.
- Research results summary, etc.
Outline and Write
Do you still think you can do without a literature review outline when translating your research into writing? You might end up having to spend too much time writing without one!
Go ahead and create an outline before you start writing your paper.
The literature review structure contains the same elements as a regular essay would:
|Part of the Paper||What to include in this part|
How do you write a literature review for a research paper?
Pay special attention to these important details as well:
- Define the general problem you’re studying without making global statements.
- Somewhere at the beginning of the paper, mention why your topic is crucial.
- Make sure to highlight only the essential points from each source. And these points should refer directly to the focus of your review.
- Explain the difference between your research and that of other sources.
- Break your findings up by concepts and categories (in defense of or opposition to a particular position).
- Synthesize the materials under consideration: compare the studies, reveal their strengths and weaknesses, highlight gaps and trends in the research, etc.
- Describe the timeframe if you’re going to comment on the topic’s timeliness.
- If you need to cite a classic or landmark study, define it as it is.
- If you replicate some landmark study, point it out.
- Keep your voice front and center. Even though a literature review describes ideas from other authors, you should maintain your voice. Try to start and end the paragraph with your statements and words.
- Like any other academic paper, you should reference a few other resources when you make a point. Always back up your explanations with evidence to confirm the validity of your words.
- Comments like “no studies were found” should always be justified.
- Always give credit to authors whenever you use their ideas. And quote reasonably. Use quotes only to highlight a specific idea or fact that exemplifies your research.
- Draw conclusions about the literature that made the most significant contributions to your study area.
