What is a literature review?
A literature review is an evaluative account of studies that relate to your research area. It goes beyond a
summary of existing literature on the topic and sets out to describe relationships between previous work and
your field of research. Its purpose is to convey established ideas in the field and to identify the strengths and
weaknesses of these arguments. The basic purposes of the literature review are to:
· Provide a context and justification for the research
· Ensure the research hasn't been done before
· Show where the research fits into the existing body of knowledge and how it was studied previously
· Highlight flaws, gaps, and controversies in previous research
· Show that the work is adding to the understanding and knowledge of the field
· Formulate questions for future research
