Website content

It is often sufficient simply to describe web pages and other website content in the text (“As of May 1, 2017, Yale’s home page listed . . .”). If a more formal citation is needed, it may be styled like the examples below. For a source that does not list a date of publication or revision, use n.d. (for “no date”) in place of the year and include an access date.

Social media content

Citations of content shared through social media can usually be limited to the text (as in the first example below). If a more formal citation is needed, a reference list entry may be appropriate. In place of a title, quote up to the first 160 characters of the post. Comments are cited in reference to the original post.
