In the Introduction
define or identify the general topic, issue, or area of concern, thus providing an appropriate
context for reviewing the literature.
point out overall trends in what has been published about the topic; or conflicts in theory,
methodology, evidence, and conclusions; or gaps in research and scholarship; or a single
problem or new perspective of immediate interest.
establish the writer's reason (point of view) for reviewing the literature; explain the
criteria
to be used in analysing and comparing literature and the
organisation of the review
(sequence); and, when necessary, state why
certain literature is or is not included (scope).
