A literature review is a critical and in-depth evaluation of previous research. It is a summary and synopsis of a particular area of research, allowing anybody reading the paper to establish why you are pursuing this particular research program. A good literature review expands upon the reasons behind selecting a particular research question.

A systematic literature review is designed to review relevant literature in your field through a highly rigorous and 'systematic' process.
The process of undertaking a systematic literature review covers not only the content found in the literature but the methods used to find the literature, what search strategies you used, how and where you searched, what was included/excluded from your research and to determine whether any gaps can be found in existing research.
