What is a literature review?
A literature review is an assessment of sources in the chosen topic of research.
💡In a literature review, you are expected to report the existing references available in your field of research, without adding new contributions.
If you are currently writing one, you've come to the right place. In the following paragraphs, we will explain the objective of a literature review, how to write one, its basic format, and lastly, some examples.
Purpose of a literature review
The four main objectives of a literature review are:
- Studying the references of your research area
- Summarizing the main arguments
- Identifying current gaps, stances, and issues
- Finally, presenting all of the above in a text
Ultimately, the main goal of a literature review is to provide the researcher with sufficient knowledge about the topic in question. Knowing where you stand, to know where you want to go.
Write the best literature review
Writing the best literature review can be easy if you cover these basic categories: Introduction, body, and conclusion.
The introduction should briefly introduce the main topic, just like the content order. The body includes a discussion of arguments in an organised way. Finally, the conclusion highlights the gaps, and issues subtracted from the literature. This basic structure will guarantee you an organised and understandable text.
Take a look at our guide on How to write a literature review to learn how to plan the structure, research, and evaluation of your literature review.
Format of a literature review
First of all, a literature review should have its own labeled section. You should indicate clearly in the table of contents where the literature can be found, and you should address this section as 'Literature Review' (see examples below).
It is not always mandatory to add a literature review in a paper. Theses and dissertation include them almost always, whereas research papers include them occasionally. Make sure to consult with your instructor for exact requirements.
There is no set amount of words for a literature review, so the length depends on the research. If you are working with a large amount of sources, it will be long. If your paper does not depend entirely on references, it will be short.

There is nothing better to understand something than an example. Take a look at these three papers featuring great literature reviews:
