What is a literature review?

In general, a literature review is a component that appears early in a research paper and is used to provide an overview of previous research on a particular topic. While there are different types of literature reviews, a literature review is generally done to gain an understanding of what has been said on the topic, identify where there is a gap in the research, and ultimately provide case for the research being undertaken.
