There are four key elements in the process of conducting a literature review:
¨ identifying the focus of the review - this will be the general topic or subject area within which the problem or issue you are investigating is set;
¨ selecting the appropriate sources of information - texts and other references;
¨ critically reviewing and evaluating the literature;
¨ writing up the review - the final element of bringing together the material you have gathered and producing a coherent rationale for your research.
