Website

A citation to website content can often be limited to a mention in the text (“As of July 19, 2008, the McDonald’s Corporation listed on its website . . .”). If a more formal citation is desired, it may be styled as in the examples below. Because such content is subject to change, include an access date or, if available, a date that the site was last modified. In the absence of a date of publication, use the access date or last-modified date as the basis of the citation.
Google. 2009. “Google Privacy Policy.” Last modified March 11. http://www.google.com/intl/en/privacypolicy.html.
