There are many reasons why it is so important to cite the sources you use in your research.
You demonstrate to your reader you've done proper research by listing sources you used to get your information.
You avoid plagiarism by quoting the words and ideas of other scholars.
You are being a responsible scholar by giving credit to other researchers and acknowledging their ideas.
You allow your reader to find the sources you used by citing them accurately in your paper by using in-text citations or footnotes in combination with a bibliography or works cited list.
Citing Your Sources
There are many different "styles" you may choose from when citing sources. Your professor will probably tell you which "style" is preferred for your class. MLA (Modern Language Association), Chicago, and APA (American Psychological Association) are three of the most commonly used citation styles, but there are hundreds.
For quick reference, there are many online sources. One of the best is the Purdue OWL. But be aware that the manual is always the most authoritative source.
