Unless a professor requires full citations in every note, you may provide the full citation in the first note citing a source, and then use shortened citations in subsequent notes.
The first note citing the source should be the full citation:
When one citation to the same work immediately follows another on the same page, "Ibid." can be used in the latter note, although you can use the other shortened note forms instead.
If reference is to a work already cited in full but not in the note immediately preceding, and only one work of the author has been used in your notes, then just the author's last name is needed. If the work has an editor instead of an author, do not add ed.
If two or more works of the same author have been cited, use the author's last name and a brief title (up to four distinctive words from the full title).
