What is a DOI?

A digital object identifier, or DOI, is a unique code assigned to each published article that helps to identify and manage the article online.

The APA style guide now requires the inclusion of the DOI when you cite a periodical (assuming that a DOI is available). Some brief examples are below; for complete citation guidelines, consult the official "Publication Manual of the APA."

Periodical with a DOI (7th edition):

Cleary, A., & Reyes, N. (2009). Scene recognition without identification. Acta Psychologica, 131, 53-62. https://doi.org/10.1234567890

Periodical with no DOI (7th edition):

Silick, T.J., & Shutte, N. S. (2006). Emotional intelligence and self esteem mediate between perceived early parental love and adult happiness. E-Journal of Applied Psychology, 2(2), 38-48. http://ojs.lib.swin.edu.au/index.php/ejap
