Citation, Documentation of Sources

Q. Do I need to repeat author names and year of publication in the same paragraph if I have already mentioned and referenced the authors at the beginning of the paragraph?

A. If it’s clear that everything you’ve written after the first mention is still referring to the same source, then there’s no need to repeat—although you might consider moving the citation to the end of the paragraph. If you’ve mentioned anyone else in between, or offered your own commentary, then you have to name the first source again.
