If you are using someone else's work or quoting someone in your papers, you must give credit where credit is due. You may be accused of a serious offense called plagarism if you don't. The Modern Language Association (MLA) has come up with with one such method to avoid just that. 

When you are using the MLA style, you briefly credit your sources in the text and then you give a complete description of the source in the Works Cited page. Below are a few common examples of how to do this. Check with your teacher to find out what method of citation they prefer.

You must give the name of the author and the page number where you found the material quoted in the text: Lack of sleep is a major hindrance for teenagers ' abiltity to learn (Douglas 10).

For all non-print sources (film, interviews, web listings, etc.), use the last name that identifies the source int the Works Cited page.

 Set the left and right margins to 1 inch and the top and bottom margins to 2 inches. Type the title: Works Cited in the top center of the page. Alphabetize the sources by the first letter of each entry (last name or title). If the entry takes up more than one line, indent the subsequent lines with 5 spaces.
