APA Manual

The Publication Manual of the American Psychological Asociation is the offical guide of APA citation formatting. You can find the manual at the reference desk and in the reference section of the library's collection.


In-Text Citations in APA Format

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 asa 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.

Books to Help With the Writing Process

The College of Marin Library has several books that can be consulted for quick help with all aspects of the writing process, including grammar, composition, and citing sources.



APA Style

APA (American Psychological Association) Style is most commonly used to write papers and cite sources within math, science, and social science classes, such as Pscyhology, Sociology, Biology, and Chemistry. 

The Publication Manual of the American Psychological Association is considered the authority on APA Style.


APA Reference Page

When you use outside sources, you will need to create a References page that tells your reader all the information they need to find the source themselves if they want to. 


See the examples below of commonly used resources. For more information about creating a Reference list, see Purdue OWL. There you will find examples of how to cite many different types of sources.
