Documenting Sources
Using MLA In-Text Citations


Read:  Chapter 21 in The Penguin Handbook (pp. 347-411).

Academic writing requires the correct documentation of all borrowed source material. Anytime you include paraphrases, summaries and quotations from another's work in your own writing, you must indicate that you have done so by providing in-text citations and a works cited page. The purpose of in-text citations is to provide an easy cross-reference to the works cited page so the reader can readily find the proper entry there and thus find out where the material cited in the text came from.

There are a number of different documentation styles. When you write a paper for a college course, you should use the documentation style specified by your academic discipline (field of study). Papers written for classes in the humanities, such as English and history, for example, use Modern Language Association (MLA) documentation format (called "style"); whereas the social sciences, such as Psychology and Education, use American Psychological Association (APA) style.
