Whenever you use another person’s ideas or words in a research paper, you must cite, or give credit, to that person. That’s called citing your source.

MLA citation style Citations must be accurate and standard so that anyone who reads your research can easily find the information you used. MLA style is a standard way of citing sources.

Works Cited list Sources are put in the Works Cited list in alphabetical order, double-spaced, and indented one-half inch. Here is an example of a final Works Cited list. Works Cited Crane, Cody. “In the Shadow of a Volcano.” Science World 4 Feb. 2008: 16-19. Walker, Sally. Volcanoes: Earth’s Inner Fire. Minneapolis: Carolrhoda, 1994.

Parenthetical citations Listing all your sources in the Works Cited list is an important part of your research paper. In the body of your paper, you also need to tell exactly where you found any information that came from other sources. You do that using a parenthetical citation.

Parenthetical citations A parenthetical citation appears in the body of your paper wherever you use another person’s ideas, facts, or words. A parenthetical citation always refers to a source in your Works Cited list.

Parenthetical citations To create a parenthetical citation, give the author’s last name and the page number(s) from the source. Put this information in parentheses at the end of the sentence, before the final punctuation. The earth’s climate can be affected if volcanic gases go into the earth’s stratosphere and form a dark mist (Walker 37). The earth’s climate can be affected if volcanic gases go into the earth’s stratosphere and form a dark mist (Walker 37). Readers can now find complete information about the source in your Works Cited list. Walker, Sally. Volcanoes: Earth’s Inner Fire. Minneapolis: Carolrhoda, 1994. Walker, Sally. Volcanoes: Earth’s Inner Fire. Minneapolis: Carolrhoda, 1994.

Parenthetical citations If the author’s name appears in the sentence, you need to cite only the page number(s) in parentheses. Walker claims that the earth’s climate can be affected if volcanic gases go into the earth’s stratosphere and form a dark mist (37). Walker claims that the earth’s climate can be affected if volcanic gases go into the earth’s stratosphere and form a dark mist (37). For sources without page numbers, like most Web sites, you should include the author’s name or the title of the source within the text instead of using parentheses.
