In referencing periodicals, what's the difference between using p. or pp. for page numbers?
This page reflects guidance from the sixth edition of the Publication Manual.
For the most current guidelines, see the Publication Manual of the American Psychological Association (7th ed.) and our Style and Grammar Guidelines page for the seventh edition.
If a periodical includes a volume number, italicize it and then change to regular type and give the page range without pp.
If the periodical does not use volume numbers, include pp. before the page numbers so the reader will understand that the numbers refer to pagination.
Use p. if the source is a page or less long. For example, precede page numbers for newspaper articles and book chapters with p. or pp.
