Chicago Style (17th Edition) Citation Guide: Websites



All citations should be double spaced and have a hanging indent.

A "hanging indent" means that each subsequent line after the first line of your citation should be indented by 0.5 inches.


All citations should use first line indent, where the first line of the footnote should be indented by 0.5 inches; all subsequent lines are not indented.

Footnotes should be the same font size and style as the rest of your paper.

See instructions for how to insert footnotes in Microsoft Word.



It can sometimes be difficult to find out who the author of a website is. Remember that an author can be a corporation or group, not only a specific person. Author information can sometimes be found under an "About" section on a website.

If there is no known author, start the citation with the title of the website instead.


The best date to use for a website is the date that the content was last updated. Otherwise look for a copyright or original publication date. Unfortunately this information may not be provided or may be hard to find. Often date information is put on the bottom of the pages of a website.

If you do not know the complete date, put as much information as you can find. For example you may have a year but no month or day.

Access Date

Chicago style does not recommend including access dates in the citation, unless no date of publication or last revision for the source may be located.
