 Chapter 2: Review of the Literature 

The important thing is to understand that your literature review should not simply be a summarized description of the works that others have published. It should take the form of a critical discussion, showing insight and an awareness of differing arguments, theories and approaches, linked at all times to your own purpose and rationale. The literature review is an assessment of a body of research that addresses a research question. The purpose of the literature review is to identify what is already known about an area of study. It may also identify questions a body of research does not answer or make a case for why further study of research questions is important.
