A literature review is a written overview of what has been said in books, articles, reports, and other types of resources about a particular topic.

Some instructors for some assignments prescribe a shorter length for a literature review section as part of a larger paper. It is possible that some literature review assignments are as short as a single page (double-spaced).

|E.g.,"While Dalhberg (1999; 2001; 2002; 2014) is the leading researcher in this area, his perspectives are being challenged by Franklin (2006), Nero (2007), and Fontina (2011), who question the traditional framework and consider alternate points of view. Fontina's emerging views on the subject (2011; 2012) are particularly important, as her work has been praised outside North America, especially by major commentators such as Haddad (2013) and Okumura (2014). What makes Fontina's work particularly impressive are her ideas about ..."|
