What is a DOI?

A DOI, or Digital Object Identifier, is a string of numbers, letters and symbols used to permanently identify an article or document and link to it on the web.

A DOI will help your reader easily locate a document from your citation. Think of it like a Social Security number for the article you’re citing — it will always refer to that article, and only that one.

APA 7th Edition requires that you have a DOI for all items if one exists, no matter if the item is print or online.
