"A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology."

"... the research you are looking for has been published; it is “literature,” sometimes abbreviated “lit.” When you review this literature, you are looking up every relevant scholarly article, book, dissertation, or other resource that has ever been published on your topic and problem or question. You are not “reviewing” it in the literal sense, but you are familiarizing yourself with it and carefully recording the publication information about these sources so you can include them in your references and bibliography. You do not need to read everything that has ever been written on your topic, because that may very well be physically impossible, but you must make sure you are familiar with all the key sources in your field that are pertinent to your problem or question."
