Literature review essay is not necessarily just the review of an old classic or the summary of well known and well read novel. A literature review may consist of almost anything that has been published like dissertations, scholarly articles and even government pamphlets dealing with some remote area policies or maybe even some governing issues. A literature review, once the topic is chosen, will necessarily survey the available written articles that are relevant to the issue and will give an overview of published information on that particular topic. So the question that now arises is, how to write literature review.
