Ibid. is traditionally used for “in the exact same place as the last footnote.” I.e., if page 8 of your manuscript includes a quote from Cecil Adams, footnoted “5, Zotti, Edward B. The Life and Times of Cecil Adams, page 338. Chicago: Chicago Reader Associates Press, 2008” and page 9 of your manuscript includes a quote from Mike Linehan found on the same page of the Zotti book, that’s when you use Ibid.
If, on the other hand, a footnote references a different page in the Zotti book (the only book by Zotti you’re using as reference), the proper cite is “Zotti, op. cit., p. 218.” Op. cit. means opus citatum (nominative) or opere citato (ablative) – meaning “(In) the cited work.”
A modern trend that seems to be fully accepted nowadays: if two sequential footnotes reference different pages of the same work, use “Ibid., p. 95” in place of the formerly “correct” construction with Op. cit..
A third, occasionally seen abbreviation is loc. cit., “in the cited place” – meaning “This would have been an ibid if a bunch of other footnotes didn’t get in the way.” If your sole reference to the Zotti book is page 338, and footnotes 5, 14, and 33 all reference that page, the first gets the full cite and the other two are "Zotti, loc. cit..
Finally, you never use any of these but Ibid. to reference one of two or more cited works by the same author. If you also cited the companion volume, Zotti’s The Art of Slug Signorino: a Retrospective, the proper second and later cites would be of the form “Zotti, Adams, p. 87” and “Zotti, Signorino, p. 1034.”
