Citation, Documentation of Sources

Q. In a footnote do the year and page number go at the beginning or at the end?

A. The page number usually goes at the end of a citation. The placement of the year depends on whether you’re using the notes-bibliography system or the author-date system. You can find a free guide to both systems at our website.
