What is a literature review?
A discussion of literature (published or unpublished) relevant to an area of study, subject area, sometimes within a certain time period.
A critical discussion: literature has to be summarised, categorised, compared.
An argument for further research (your research).
Organised according to ideas, themes, concepts, not authors.
A literature review is a scholarly document that reviews the breadth and depth of literature on a topic in order to determine what is known. It’s a summary of the literature, but more importantly, it’s a synthesis and evaluation of the literature. It is not a paper explaining “how to do” something. It’s not an introduction to a topic. The purpose of a literature review is to determine what the research says–and doesn’t say–about the topic (Ollhoff 2011, p1).
