When you research a topic you may use information from articles, books, or the Web to support your ideas. However, you must credit the original authors of these sources by citing them. This serves two important functions.
NoodleTools is an free online tool for creating works cited lists. Use it with MLA, APA, or Chicago styles. It helps you create your citations, and generates your bibliography.
MLA style, developed by the Modern Language Association, is used for English, foreign languages and general topics. MLA requires parenthetical citations within the text and a corresponding bibliography or works cited list at the end of the paper.
APA (American Psychological Association) style is used for scientific and technical research. Instructors in behavioral science and hard science courses may require you to use APA style for your references or bibliography page.
Chicago style is sometimes used for history and the humanities. Chicago style uses superscript numbers within the text to refer readers to corresponding footnotes at the end of the page. A bibliography is generally required as well.
