DOI stands for digital object identifier. This is a unique number assigned to an electronic resource such as an article.
There are no industry standards for assigning DOIs to articles, and many scholarly articles still lack DOIs. Some databases include the DOI in article records, but not all.
APA citation rules ask for a DOI when available. If the DOI is not available, you can learn how to cite using the web address for the journal's home page.
