APA Citation Guides
How to Cite Sources According to the APA Style Guide
This brief guide is to be used to organize your References page. The guide is based on the Publication Manual of the American Psychological Association, Sixth Edition (LBF76.7.P83 2010, Copley Library Reference). Consult the manual to cite materials not included (e.g. advertisements, speeches, etc.), as well as for Copyright or Content Notes.
In-text Citations: Basics
- When the names of the authors of a source are part of the formal structure of the sentence, the year of publication appears in parenthesis following the identification of the authors. E.g. Wirth and Mitchell (1994) found that although there was a reduction in insulin dosage over a period of two weeks in the treatment condition compared to the control condition, the difference was not statistically significant.
- When the authors of a source are not part of the formal structure of the sentence, both the authors and year of publication appear in parentheses. E.g. Reviews of research on religion and health have concluded that at least some types of religious behaviors are related to higher levels of physical and mental health (Payne, Bergin, Bielema, & Jenkins, 1991).
- When a direct quotation is used, always include the author, year, and page number as part of the citation. E.g. Patients receiving prayer had "less congestive heart failure, required less diuretic and antibiotic therapy, had fewer episodes of pneumonia, had fewer cardiac arrests, and were less frequently intubated and ventilated" (Byrd, 1988, p. 829).
