Citing Your Sources

A general guide to citations and styles commonly used at USNA.

Chicago Style

The Chicago Manual of Style is most often used for history and philosophy papers.

WARNING Within Chicago style are two systems for formatting citations. Most likely you'll use the notes and bibliography system, but your professor may prefer the author-date system.

Examples

In the notes and bibliography system, use a superscript number like this 1 to refer to a citation found in a footnote at the bottom of the page or an endnote at the end of the paper. Here are what book, journal article, and website citations look like in the note and then in the bibliography.

  Footnote or Endnote Bibliography
Book 1. Author last name, Shortened Title, XX.

1. Goat, Superiority of Midshipmen, 26.
Author (Last name, first name). Title in Title Case and Italics, (City: Publisher, Date), XX-XX.

Goat, Bill T. "Winning Football Strategies Against Army," Midshipman Review 23, no. 4 (2013): 25-30, accessed October 13, 2016, doi: 12345.
Website Because the information available on websites vary greatly, it's easiest to go directly to the style manual for examples. The style manual recommends citing websites fully in the notes and not including them in the bibliography.

In the author-date system, use the author's last name, the publication year, and page number in parentheses like this - (Goat 1845, 25) - after your citation to refer to an item on your "References" or "Works Cited" list. If you use the author's name in the text, just include the publication year in parentheses like this - "as Goat (1845) recommends."

  "References" or "Works Cited" page

Turabian

You may see or hear an instruction to use "Turabian style." This is essentially Chicago Style and refers to A Manual for Writers of Research Papers, These, and Dissertations first written by Kate Turabian. "Chicago" and "Turabian" style are often used interchangeably or in combination, and the differences between them are small. You are safe using Chicago Style (which is accessible online) in place of Turabian (which is not).

The main difference between the two style guides is Chicago covers all scholarly writing, and Turabian focuses student writing.
