Special issues and supplements
Parenthetical citations–reference list style: citing specific types of sources
Part II. Source Citation

A journal issue devoted to a single theme is known as a special issue. It carries a normal volume and issue number. If a special issue has a title and an editor of its own, include both in a reference list entry. The title is given in roman type and enclosed in quotation marks. In a parenthetical citation, give only the author of the part cited.

R: Jones, Matthew L. 2001. Descartes's geometry as a spiritual exercise. In “Things,” ed. Bill Brown. Special issue, Critical Inquiry 28, no. 1 (Autumn): 40—71.

P: (Jones 2001, 43—44)

If you need to cite the issue as a whole, omit the article information.

R: Brown, Bill, ed. 2001. “Things.” Special issue, Critical Inquiry 28, no. 1 (Autumn).

A journal supplement may also have a title and an author or editor of its own. Unlike a special issue, it is numbered separately from the regular issues of the journal, often with S as part of its page numbers. Use a comma between the volume number and the supplement number.
