Follow MLA style by typing "Works Cited" at the top of a new page at the end of your essay. Alphabetize entries by the last names of the authors with a half inch hanging indent after each entries' first line, if needed. Cite book sources according to MLA format: author's last name, first name, book title, additional information, city of publication, publishing company and publication date. For example: Boorstin, Daniel J. The Creators: A History of the Heroes of the Imagination. New York: Random, 1992.
Add a "References" page using the American Psychological Association (APA) style. The references are organized alphabetically by the last names of the authors with a half inch hanging indent after each entries' first line, as needed. Reference book sources according to APA style: author's last name, first and middle initial, year of publication, book title, city of publication and publisher. For example: Springer, S. P. & Deutsch, G. (1985). Left brain, right brain (Rev. ed.). New York: W. H. Freeman.
Use the Chicago Manual of Style to create a Notes-Bibliography section at the end of the essay with the heading "Bibliography" centered at the top of the page. Use either a hanging indent after each entries' first line or format each entry with a first-line indent. List sources alphabetically according to the author's last name. Follow CMS style: author's last name, first name, book title, city of publication, publisher and year of publication. For example: Zimmer, Gary. The Biological Farmer. Chicago: University of Chicago Press, 1999.
Adopt the Columbia Online Style synthesizing several different citation methods according to industry. For example, humanities citations will format exactly like MLA or CMS bibliographies. Cite an electronic book according to COS by: author's last name, first name, title of work, title of longer work, date of document, Internet address and Date accessed. For example: Hatchuel, Sarah. "Leading the Gaze: From Showing to Telling in Kenneth Branagh's Henry V and Hamlet." Early Modern Literary Studies. May 2000. http://www.shu.ac.uk/emls/06-1/06-1toc.htm (1 Sept. 2000).
