Short-Form Citation

A short-form citation is the compressed reference used in the second and subsequent times a source is cited within a work. The first citation carries the source's full apparatus — author, title, publisher, date, page — and the short forms that follow strip this down to just enough to identify the source unambiguously: usually author's surname and a page number, sometimes a short title if two works by the same author are in play.

Short forms exist because full citations, repeated, become unreadable. A paragraph in which the same book is cited four times does not need the publisher's city four times. But the compression must remain unambiguous: if the writer cites two Smiths, or two books by the same Smith, the short form has to disambiguate — 'Smith, Ethics 42' rather than 'Smith 42'.

Different style manuals structure short forms differently. Chicago uses 'Smith, Title, page'; MLA uses 'Smith page'; Bluebook has its own compressed forms with 'id.' and 'supra' doing much of the work. The choice of style matters less than internal consistency; a manuscript that switches short-form conventions between chapters reads as unedited.

Common mistake: using a short form for a source that has not yet appeared in full form. A reader who reaches 'Smith 42' and has never met Smith in this text has been failed by the citation system. The first mention is always full; short forms are a courtesy the writer earns by having done the full citation once.
