Citation, Documentation of Sources

Q. I often have difficulty deciding how to cite translations with critical commentaries of ancient texts. What if I’m citing a critical comment or note made by the translator/Loeb editor? The bibliography entry is

Aristotle. Nicomachean Ethics. Rev. ed. Loeb Classical Library. 1934.

But how do I refer to something the editor/translator says in that edition? If it’s like “Rackham in Aristotle, Nicomachean Ethics, p. xxx,” then do I need some separate bib entry that mentions Rackham?

A. Yes, that’s right. Your bibliography entry should include the name of the editor, like this:

Aristotle. Nicomachean Ethics. Rev. ed. Edited by H. Rackham. Loeb Classical Library. Harvard University Press, 1934.

If the editor is more central to your discussion than the author, you may put the bibliography entry under the name of the editor instead. A cross-reference will aid the reader.

Aristotle. See Rackham, H.

Rackham, H., ed. Nicomachean Ethics, by Aristotle. Rev. ed. Loeb Classical Library. Harvard University Press, 1934.
