How to Write a Literature Review | Tips and Common Mistakes to Avoid

Writing a literature review can seem overwhelming, but with the right strategy, it can be a rewarding and feasible task. A well-written literature review accomplishes several objectives: it offers a thorough summary of the body of knowledge already available on a given subject, points out knowledge gaps, and lays the groundwork for future research. 


Learning how to write a literature review is essential whether you're a student, trying to do well on your assignments, a researcher starting an entirely novel endeavor, or someone looking to learn more about a certain subject. This guide will lead you through the process in a methodical manner to assist you in creating a well-thought-out and impactful literature review.


What is a Literature Review?


A literature review is a type of academic article where the existing research on a certain topic is summarized and evaluated.

Narrative Reviews

A narrative review provides a thorough summary of a subject by combining the results of several investigations into a logical story. They are not constrained by rigid methodological requirements and are usually used to present a wide viewpoint on a subject.


Systematic Literature Review

Systematic reviews are more precise and methodical, employing a predetermined process to examine, assess, and combine results from various investigations. This method reduces bias and offers high-quality data on a particular study subject.


Scoping Reviews 

Scoping reviews highlight the key ideas that underpin a field of study while also defining the primary sources and categories of available data. They are useful for making concepts more clear and for pointing out gaps in the body of knowledge.
