Page numbers and other locating information
Parenthetical citations–reference list style: citing specific types of sources
Part II. Source Citation

For a reference list entry, give the full span of page numbers for the article (see 23.2.4). By convention, page numbers of journal articles in reference lists follow colons rather than commas. When additional date information in parentheses immediately precedes the colon, leave a space after the colon; when the volume or issue number immediately precedes the colon, do not leave a space after it.

If you cite a particular passage in a parenthetical citation, give only the specific page(s) cited, preceded by a comma (not a colon).
