A literature review is a central part of any research project, as it sets your research in context and identifies how it fits with the research that has already been done. You may be asked to write a literature review as part of a thesis, dissertation, or longer project, or as a separate assignment to progress the research.
Essentially it is a "re" view or "look again" at what has already been written about your research topic.

► Explain what the strengths and weaknesses of that information and those ideas might be

► Your literature searching abilities
► You can critical appraise information to judge its trustworthiness, value and relevance
► You have learnt from others
► Your research is a starting point for new ideas
