Research students always find problem with literature review.
They sometimes get it confused with either introduction or with abstract. Literature
review is different from both of them, and is of immense importance in any research
based witting.
Ø
What is literature review?
Research is an ongoing process it never ends; whenever a new research
is conducted it adds something new to the already existing body of knowledge
and findings about the topic. Thus a new research is not conducted in vacuum, rather
a continuation of the previous ones. Therefore a link must be established
between your research and the previous ones, when you mention the work of the
previous researchers on the topic in your own research work it called
literature review.
The new researchers are therefore required to search for
articles and other relevant materials which address the topic under their consideration.
Additional information and access to more relevant sources can be acquired from
the bibliography list of the relevant works.
Ø
Why it is mentioned in the research work?
The primary purpose for mentioning the literature review in
your research work is to show that the aspect of the topic which you are going
to conduct research on has not been covered by the previous researches,
otherwise there is no need to repeat a similar result but to do something
different. This is the point wherein you reflect a justification of your research
and give a rationale to go ahead with your plan.
Ø
How it is reported in the research work?
The major aspects and findings of each research must be put
in brief. Care must be taken about the reliance of the materials to your research.
The body of the previous researches would certainly be large, therefore you
have to set a boundary, and limit it. You may limit it by putting a limit of certain age or date
etc. Literature review can be organized
according to the chronological order or variables of the study. If the topic is
of controversial nature then report the reviews in groups so that views of the
different schools of thought may get due coverage.
