Chicago (17th ed.) Citation Style Guide: Shortened Citations / Ibid.

Shortened Citations (14.29, 14.30)

"When to use shortened citations.  To reduce the bulk of documentation in works that use footnotes or endnotes, subsequent citations of sources already given in full - either in a previous note or in a bibliography that provides complete bibliographic data - should be shortened whenever possible....The short form, as distinct from an abbreviation, should include enough information to remind readers of the full title or to lead them to the appropriate entry in the bibliography."  (The Chicago Manual of Style, 17th ed., pp. 757-758)

"Basic Structure of the short form.  The most common short form consists of the last name of the author and the main title of the work cited, usually shortened if more than four words." (The Chicago Manual of Style, 17th ed., p. 758)

Shortened Citations versus "ibid." (14.34)

"Shortened citations versus "ibid."  The abbreviation ibid. (from ibidem, "in the same place") usually refers to a single work cited in the note immediately preceding.  In a departure from previous editions, Chicago discourages the use of ibid. in favour of shortened avoid repetition, the title of a work just cited may be omitted.  Shortened citations generally take up less than a line, meaning that ibid. saves no space, and in electronic formats that link to one note at a time, ibid. risks confusing the reader." (The Chicago Manual of Style, 17th ed., p. 759)
