In the text of your paper, you must document sources from which you are quoting or paraphrasing, using brief parenthetical citations that correspond to your alphabetical list of works cited at the end of the paper.
Here is an example:
Ancient writers attributed the invention of the monochord to Pythagoras, who lived in the sixth century BC (Marcuse 197).
The parenthetical citation “(Marcuse 197)” tells the reader that the information in the sentence was derived from page 197 of a work by an author named Marcuse. If the reader wants more information about this source, he/she can turn to the works cited list, where a complete citation for Marcuse’s work will be found.
If no author is given, include a brief version of the title of the work, along with the page number. If you are citing an article with no author, put the article title in quotes. If you are citing a book with no author, italicize the title of the book.
Example:
By most estimates, "Iraq has the fourth-largest oil reserves in the world behind Saudi Arabia, Canada and Iran" ("Deterring Foreign Investors" 61).
This in-text citation refers back to this entry in the works cited list:
"Deterring Foreign Investors." The Economist 26 Sept 2009: 61-62. Print.
