The source tells readers where the work was published or can be retrieved. Depending on the reference type, it may include a publisher, journal, platform, database, DOI, or URL.

First check whether the work has a DOI. Avoid keeping both a DOI and a URL that lead to the same content. Confirm that the link uses a current format, does not end with an added period, and includes a database name only when it is needed to retrieve the work.

The Sources, DOIs, and URLs in APA references guide develops each decision.
