American Psychological Association style requires a citation for every page number corresponding to quoted material even when the same source is quoted multiple times. APA also has a format for citing multiple pages that correspond to one reference.
Citing Different Pages From the Same Source
Whenever you reference a source in the body of your text, APA style requires an in-text citation noting the source. A page number is not required for paraphrased content, but is needed for all direct quotes. Whether you cite the source within the text of the sentence (a signal phrase) or in parentheses at the end of the line, a page number should be included for all direct quotes. Besides the page number, the citation should include the author's name and the publication date. If you use a signal phrase, place the date in parentheses after the author's name and the page number at the end of the line. For a parenthetical citation, place the name, date and page number in parentheses at the end of the line.
Signal phrase example: According to Róheim (1972), Yumu and Pindupi cultures also include a myth in which "the boy belongs to the any totem" (p. 79).
Parenthetical example: Yumu and Pindupi cultures also include a myth in which "the boy belongs to the any totem" (Róheim, 1972, p. 79).
When quoting multiple items from the same source in your text, a citation is used for all quotes. If these quotes come from multiple pages, include the page number for each quote:
The concept of the hierophany, an "irruption of the sacred" (Eliade, 1987, p. 26) gives ritual and myth its power of meaning-making. Because of this numinous quality, "even the most barbarous act and the most aberrant behavior have divine, transhuman models" (Eliade, 1987, p. 104).
Citing Multiple Pages From a Source
When citing a quote that stretches over multiple pages, all the pages are noted in the in-text citation. The abbreviation "pp." is used in place of "p." to designate that there are multiple pages:
The troubling falsehood of authenticity is shown by the "political irony in the fact that the British learned the technique of fingerprinting from the Bengalis and then used it to control them" (Doniger, 1998, pp. 32-33).
