The review of literature serves the following purposes in conducting research work:
1.  It provides theories, ideas, explanations or hypothesis which may prove useful in the
    formulation of a new problem.
2.  It indicates whether the evidence already available solves the problem adequately without
    requiring further investigation. It avoids the replication.
3.  It provides the sources for hypothesis. The researcher can formulate research hypothesis
    on the basis of available studies.
4.  It suggests method, procedure, sources of data and statistical techniques appropriate to the
    solution of the problem.
5.  It locates comparative data and findings useful in the interpretation and discussion of results.
    The conclusions drawn in the related studies may be significantly compared and may be
    used as the subject for the findings of the study.
6.  It helps in developing experts and general scholarship of the investigator in the area
    investigated.
7.  It contributes towards the accurate knowledge of the evidence or literature in one’s area of
    activity is a good avenue towards making oneself. This knowledge is an asset ever afterwards,
    whether one is employed in an institution of higher learning or a research organization.
Bruce W. Tuckman (1978) has enumerated the following purposes of the review:

Edward L. Vockell (1983) has pointed out the following two purposes:
• The main purpose of this review is to put the hypothesis to be examined in the research
    report into its proper context.
• Secondary purposes of this part of the report are to provide readers with guidelines regarding
    where they can look to find more information and to establish the author’s credential by
    letting readers know that the researcher is aware of what has been going on with regard to
    the current and related topics.
