When citing a work on a Web site, should I use the original publication date or the last-updated date?
As the MLA Handbook notes, “When a source carries more than one date, cite the date that is most meaningful or most relevant to your use of the source” (42). Thus, if you are citing a work on the Web that lists both an original publication date and a last-updated date, use the last-updated date or, if provided instead, the last-reviewed date. Providing the last-updated or last-reviewed date lets your reader know that the information you are citing is current.
For an example of a works-cited-list entry listing a last-reviewed date, see our post on crediting the reviewers of an online article.
