Loc. cit. (Latin, short for loco citato, meaning "in the place cited") is a footnote or endnote term used to repeat the title and page number for a given work (and author). Loc. cit. is used in place of ibid. when the reference is not only to the work immediately preceding, but also refers to the same page. Therefore, loc. cit. is never followed by volume or page numbers. Loc. cit. may be contrasted with op. cit. (opere citato, "in the work cited"), in which reference is made to a work previously cited, but to a different page within that work.
