A literature review can be a precursor to the introduction of a research paper, or it can be an entire paper in itself, acting as the first stage of large research projects and allowing the supervisor to ascertain that the student is on the correct path.A literature review is a critical and in depth evaluation of previous research.The process of reviewing the literature requires different kinds of activities and ways of thinking.
It is a summary and synopsis of a particular area of research, allowing anybody reading the paper to establish why you are pursuing this particular research.
A good literature review expands on the reasons behind selecting a particular research question.
In such a case, the review usually precedes the methodology and results sections of the work.
Producing a literature review may also be part of graduate and post-graduate student work, including in the preparation of a thesis, dissertation, or a journal article.
All sides of an argument must be clearly explained, to avoid bias, and areas of agreement and disagreement should be highlighted.
A literature review is likewise not a collection of quotes and paraphrasing from other sources.
Otherwise, this is usually perceived as being a little lazy, and it is better to organize the review around ideas and individual points.
As a general rule, especially for a longer review, each paragraph should address one point, and present and evaluate all of the available evidence, from all possible differing points of view.
This is why it is still good practice to begin research in an academic library.
Any journals found there can be regarded as safe and credible.
