“A literature review is a survey of everything that has been written about a particular topic, theory, or research question. It may provide the background for a larger work, or it may stand on its own. Much more than a list of sources, an effective literature review analyzes and synthesizes information about key themes and issues.” --UTSC, Writing Centre
