What is a Literature Review?

A literature review is an analytical summary of the research literature on a specific topic. It involves literature searching and critical appraisal of individual studies before writing the review.

It is usually written as part of a thesis or a research article that is being submitted to a journal for publication, and provides a rationale for your research in terms of what has gone before, a justification of its value and significance.
