In higher degree research, it is expected that no significant work is left in the Literature Review. Undergraduate research would be expected to discuss all of the most prominent research. A literature review is a critical discussion of all the significant available literature that contributes to the understanding of a subject. A literature review is a written document that presents a logically argued case. There are six steps in the literature review process: topic selection, literature search; developing an argument; literature survey; critique and write a review. The literature review process requires four separate skills such as the ability to search appropriate sources and scan the literature efficiently, to use manual and online methods, to identify and obtain a set of useful articles, chapters and books; the ability to judge a source based on a number of criteria, including the source itself, the author and the subject; the ability to examine and analyse the content of the literature systematically; and the ability to synthesize the various concepts and evidence a researcher has found into a structured piece of discursive prose that provides context and background on the research in the area.
