  APA In-Text Citation

Basic Format for a Short Quote

Introduce the quotation with a signal phrase that includes the author’s last name followed by the year of publication in parentheses. Put the page number (preceded by “p.”) in parentheses after the quotation.

Critser (2003) noted that despite growing numbers of overweight Americans, many health care providers still “remain either in ignorance or outright denial about the health danger to the poor and the young” (p. 5).

Basic Format for a Longer Quote

Longer quotes are indented to set them off.

A Report by the Henry J. Kaiser Family Foundation (2004) outlined trends that may have contributed to the childhood obesity crisis, including food advertising for children as well as

a reduction in physical education classes and after-school athletic programs, an increase in the availablity of sodas and snacks in public schools, a growth in the number of fast food outlets..., and the increasing number of highly processed, high-calorie and high-fat grocery products.  (p. 1)

Basic Format for a Summary or Paraphrase 

Include the author’s last name and the year either in a signal phrase introducing the material or in parentheses following it.
According to Carmona (2004), the cost of treating obesity is exceeded only by the cost of treating illnesses from tobacco use.
