These e-modules about Doing a literature review explain why literature reviews are needed, how you can conduct one and how to report. The focus is the literature review within a dissertation or thesis, but many of the ideas are transferable to other kinds of writing, such as a peer-reviewed publication (typically in a journal, or - depending upon the discipline - as a book chapter), or a report resulting from a research project or other commissioned research.
Do I really need a literature review?
The literature review helps place your research in the context of what has already been done in the field. The literature review is a component of most scholarly writing. To some extent, particularly with postgraduate research, the literature review can become a project in itself. It is an important showcase of your talents, of: understanding, interpretation, analysis, clarity of thought, synthesis, and development of argument. The process of conducting and reporting can help you clarify your own thoughts about your topic. It can also establish a framework within which to present and analyze the findings.
