How to Cite a Source

Style guides offer standardized methods for crediting sources that writers use in their research.

Traditional Citations
The two best-known style guides are published by the American Psychological Association (APA) and the Modern Language Association (MLA). Both include formulas for constructing footnotes, endnotes and works cited lists.

• APA Style
  Primarily for writers in the sciences.  To learn more about APA style, visit http://www.apastyle.org/elecref.html.
   

• MLA Style
  Primarily for writers in the arts and humanities. To learn more, explore the MLA site at http://www.mla.org or go directly to information about citing sources at http://www.mla.org/style_faq4.
