What is DOI in a citation?
Answer
A digital object identifier (DOI) is a unique identification number assigned to an item, such as an electronic journal article, book chapter, image, or data set. Publisher might assign DOIs to help permanently identify and link to content available online. Unlike a regular URL, a DOI is a persistent identifier, which means it will not change even if the item is moved or renamed.
In APA style, include a DOI in your citation whenever it is available. You can usually find the DOI listed in databases alongside the article details.
