The literature review

The literature review is a working document: it will be scoped and updated throughout the research process in response to changes both in the research question and the focus of the project. The literature review is the heart of the thesis, establishing the framework and terms of reference as well as the candidate’s understanding of the topic. It is the map upon which the scholar places his/her own “pin” to locate their work within the discipline and field. Many PhD examiners will head straight to the Literature Review chapter when examining a thesis. If this chapter is not of doctoral quality and standard then it can have a damaging impact on the rest of the thesis.

"An analytical synthesis covering all known literature on the problem, including that in other languages demonstrating high level and conceptual thinking and both summative and formative evaluation of previous work on the problem. There is also depth and breadth of discussion on relevant philosophical traditions and the ways in which they relate to the problem"

C. Hart, Doing a Literature Review (Sage, 1998)
