Citing Online Sources

Basic Guidance on Citing Online Sources

If the material is available in print and online forms, a reference to the print form is preferable (under the rationale that print sources are less likely to change than online sources), or you may want to give both sources.

The goals of citing online references are the same as for any citations: (1) credit the author and (2) enable the reader to find the material.

The citation should be as close as possible to the styles we use for print forms. Basically, give

  • author (if there is one),
  • title,
  • any other information (such as journal or book title or web page),
  • a date (for a bibliography/reference list, the date follows the author or, if no author, the title; for a footnote/source note, it follows the publisher inside the parentheses), and
  • the path to find the material.

Be sure to check that the path you give works.

For more information about citing online sources, see CMS 15.50–15.52 and the CMS-style citation quick guide.

Formatting Online Sources

Websites

Put the URL at the end of the main citation, preceded by a period.

Note: For website addresses cited in print, do not include “http://” in the address if it is followed by “www.” and the address works without “http://”.
