The reference list is arranged in alphabetical order by the first item in the reference which is generally the author. The entire list is double spaced (even within citations), and each citation uses a hanging indent so that the first line is flush with the left margin and any subsequent lines are indented.
Author, A.A., & Second, A. A. (Year). Title of the article: Subtitle of the article. Title of the Journal, vol(issue), page range https://doi.org/[insert article doi]
A Digital object Identifier is a permanent address to an article or other electronic source that will continue to lead a reader to the source even if the source's web address has changed multiple times. For this reason, DOIs are the preferred retrieval information for APA sources whenever they are available.
Not sure what the DOI for a source is? Go to www.crossref.org. Click on Search Metadata, and enter the title of the your article into the search box. If your article has a DOI, it will appear on the results page. Watch the video tutorial below or view the print tutorial.
Not every article will have a DOI. Only those articles from scholarly journals published from about the mid-1990's on.
As of 3/1/2017, the APA's preferred format for DOIs is to have https://doi.org/ in front of the actual DOI. For example:
Morey, C. C., Cong, Y., Zheng, Y., Price, M., & Morey, R. D. (2015). The color-sharing bonus: Roles of perceptual organization and attentive processes in visual working memory. Archives of Scientific Psychology, 3, 18–29. https://doi.org/10.1037/arc0000014

Occasonally you may have mutliple sources with the same author and the same publication year. To distinguish these sources from each other, you add a lowercase letter after the year, in alphabetical order of where the references appear in the reference list. For example,
(CDC, 2017a)
According to the CDC (2017b)...
In the reference list, the entries are alphabetized by title to determine which is "a" and which is "b." The reference marked 2017a appears in the reference list before 2017b. The a and the b will also be in the reference list. For example,
Centers for Disease Control and Prevention. (2017a). Type 1 diabetes. Retrieved from https://www.cdc.gov/diabetes/basics/type2.html
Centers for Disease Control and Prevention. (2017b). Type 2 diabetes. Retrieved from https://www.cdc.gov/diabetes/basics/type2.html
