Citation, Documentation of Sources

Q. The bibliography I am editing has a few entries where multiple editions of the same book were used as sources. Do I need to create separate citations for each edition, or is there a way to combine them into one? The author currently has written out the citation for the first edition, then listed other editions at the end of the citation.

A. The author’s method sounds good. You can see examples of ways to do this at CMOS 14.119. In the notes, citations of page numbers should refer to the specific edition, however, since the pagination might not be the same in all editions.
