What is a literature review?
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.

Purpose of a literature review
The purpose of a literature review is to:
- establish a theoretical framework for your topic / subject area
- define key terms, definitions and terminology
- identify studies, models, case studies etc supporting your topic
- define / establish your area of study, ie your research topic.
The three key points of a literature review:
- Tell me what the research says (theory).
- Tell me how the research was carried out (methodology).
- Tell me what is missing, ie the gap that your research intends to fill.
