Citation Styles

Citation styles differ mostly in the location, order, and syntax of information about references. The number and diversity of citation styles reflect different priorities with respect to concision, readability, dates, authors, publications, and, of course, style.

There are also two major divisions within most citation styles: documentary-note style and parenthetical style. Documentary-note style is the standard form of documenting sources. It involves using either footnotes or endnotes, so that information about your sources is readily available to your readers but does not interfere with their reading of your work. For more information on footnotes and endnotes, click here.


In the parenthetical style, sometimes called the "author-date" style or "in-text" style, references to sources are made in the body of the work itself, through parentheses. An example of this would be the following sentence, taken from page 23 of a book written by Professor Scott in 1999:


This is generally considered an abbreviated form of citation, and it does not require footnotes or endnotes, although it does require the equivalent of a "Works Cited" page at the end of the paper. It is easier to write, but might interfere with how smoothly your work reads.

With so many different citation styles, how do you know which one is right for your paper? First, we strongly recommend asking your instructor. There are several factors which go into determining the appropriate citation style, including discipline (priorities in an English class might differ from those of a Psychology class, for example), academic expectations (papers intended for publication might be subject to different standards than mid-term papers), the research aims of an assignment, and the individual preference of your instructor.

If you want to learn more about using a particular citation style, we have provided links to more specific resources below. Just choose the appropriate discipline from the menu on the left, or scroll down until you find the style that interests you.
