What is a Literature Review?
"A literature review is a written document that presents a logically argued case founded on a comprehensive understanding of the current state of knowledge about a topic of study. This case establishes a convincing thesis to answer the study's question."
(Machi, L.A. & McEvoy, B.T. 2009, The literature review: six steps to success, p. 4)
What is a Literature review:
- Is a critical, in-depth evaluation of research already undertaken on a specific topic.
- Allows you to demonstrate your ability to identify relevant information and to outline existing knowledge.
- Identifies the gap in the research that your work will address and produce a rationale for your own research.
- Is not a list of all previous research, but rather an assessment of the research.
This guide provides general guidance - check with your supervisor/lecturer/school to find out if there are any specific requirements for your literature review before proceeding.
