The seventh edition of the Publication Manual of the American Psychological Association was released in October 2019. Be sure to check with your instructor about which edition to use.
Since 2000 there has been an effort to assign everything that exists in the digital world such as online articles with a unique number called a Digital Object Identifier or a DOI. The DOI is unique, permanent, and persistent. It remains the same despite changes in URL's or permanent removal from the Internet.
In APA and AMA styles, use the DOI in citations whenever possible. If no DOI is present, try the free DOI lookup from CrossRef. For more information, watch the short video, Citing an article with a DOI and without a DOI (University of Maryland University College). If you have questions, Webster students, faculty and staff should contact the Webster U. Library Reference Department (info in the Help box).

These websites may assist you in building citations for your bibliographies / references page. Please note that citation generators rely on the user’s input and can only follow patterns set by their programmers. They cannot correct inaccurate or incomplete information and may not be using the most recent edition of the style manual required for your assignment.
Always check your citations against the official style manual to make sure they are correct before copying and pasting them into your paper.
