About APA Style
American Psychological Association (APA) style is commonly used for citing references in student papers in science and social science courses, such as Psychology, Nursing, and Social Work.
The purpose of documentation is to:
- Identify (cite) other people’s ideas and information used within your essay or term paper.
- Indicate the authors or sources of these in a References list at the end of your paper.
This guide is based on the APA Manual (6th ed.) that was published in 2009.
The following sections provide you with information and examples that will help you to cite the sources that you come across during your research.
For more detailed information, refer to the APA Manual (6th ed.) available at the Reference Desk in the Library, ask your instructor, or Ask Us.
What's Different in the 6th Edition
APA recently published a new manual of style.
Some of the changes include:
- the use of Digital Object Identifiers (DOI) in references to print and electronic sources (when available). See pages 188 to 192 in the APA Manual for more information.
- expanded coverage of online resources
To learn more about the changes made in the new edition, check out the "What's New" section on the official APA Website.
You may also want to check out the APA blog to learn more about the corrections made to the new APA manual (6th ed.). The blog also contains helpful information on such topics as using DOIs and citing specific sources.

Give credit to all sources from which you have taken information, whether you have directly quoted, paraphrased, or summarized the author’s words. Failing to document your sources constitutes plagiarism.
ALA style calls for briefly identifying a source at the point of reference within the text (body) of your paper. In parentheses, include as specified only the information required to identify the source in the Reference list at the end of the paper.
