APA Format & Citation Style, 6th edition

Getting Started

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 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.

Use the side navigation for further information on how citing different sources. 

APA's Official Resources

Digital Object Identifier (DOI) (pp. 188-192)

What is a DOI? A DOI (digital object identifier) is a unique alphanumeric string assigned by a registration agency (the International DOI Foundation) to identify content and provide a persistent link to its location on the internet. 

NOTE: It is regarded as the most important part of the citation because it will accurately direct users to the specific article.

Think of it as a "digital fingerprint" or an article's DNA!

FYI - Updated rules on using DOI (March 2017):

Correct:  

  • doi:10.1186/1471-2288-12-114
  • http://doi:10.1186/1471-2288-12-114

Incorrect:     

  • doi:http://doi:10.1186/1471-2288-12-114
  • Retrieved from http://doi:10.1186/1471-2288-12-114

(Above information from The APA blog on DOI. This is APA's official blog and their staff provides excellent examples on APA formatting/citations.)
