Citation, Documentation of Sources

Q. In my footnotes, I want to cite something as well as explain what it is I have cited, because I do not want to insert the info in the body of my paragraph. How do I do this? Does the citation go first or the explanation?

A. Put your citation first and the explanation after. (When an explanation comes first in a note, a citation after it might appear to be in support of the explanation rather than in support of something in the text.)
