When the same page (or page range) in the same source is cited more than once in one paragraph, the parenthetical citation can be placed after the last reference or at the end of the paragraph (but preceding the final period). When referring to different pages in the same source, however, include a full parenthetical citation at the first reference; subsequent citations need only include page numbers.

The order in which they are given may depend on what is being cited, and in what order, or it may reflect the relative importance of the items cited. If neither criterion applies, alphabetical or chronological order may be appropriate.
Additional works by the same author(s) are cited by date only, separated by commas except where page numbers are required.
