APA (6/e) Style Guide

A guide to help users create citations using APA (American Psychological Association) style.


Welcome to the NYMC APA Style LibGuide. 

This page is intended to be used as a guide. Please refer to the Publication Manual of the American Psychological Association (6th ed.) as a definitive source (See NOTE at bottom of this page). The library has 3 copies on 2 hour Reserve, WZ345 P976 2010, you can ask for a copy at the Service Desk. The Reference Librarians at the Health Sciences Library are available to help you interpret correct APA style. 

American Psychological Association (APA) style is commonly used for citing references in student papers in science, medical, public health, health sciences and nursing as well as the social science.

The following sections provide you with information and examples that will help you to cite the sources that you come across during your research. There are additional types of sources that you might be interested in citing, and for those sources we recommend referring to the APA Publication Manual. For the most up to date information, you can also refer to the APA Style website .

Keep in mind that APA Style refers to:

  • the format & structure of your paper.
  • how you cite other authors within the body of your paper.
  • how you compile a references page at the end of your paper.


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.


The American Psychological Association maintains a page of supplemental materials  that are referenced from, but not printed in, the actual manual. A list of corrections  to the first printing (July 2009) was released online. Please refer to this list  for corrections that might not appear in your version of the APA Publication Manual.)
