APA style recommends that writers give the author of a given source, the year of publication, and sometimes a page number in parentheses, when composing an in-text citation. Usually the author name is given in a signal phrase, but if not, the author's name, year, and page number in parentheses at the end of the quotation.
Here is the basic format for a quotation as given in section 64a of Rules for Writers, 7th edition:
Critser (2003) noted that despite growing numbers of overweight Americans, many health providers still "remain either in ignorance or outright denial about the health danger to the poor and the young" (p. 5).
For additional examples of in-text citations in APA style, consult Rules for Writers or Purdue University's OWL page for APA style.
