What is a DOI?


DOI is a Digital Object Identifier.

This sequence of characters assigned to an online article provides a persistent link to a published online article. Each persistent link provides

  • an abstract of the article 
  • an opportunity to acquire the full text version of the article.

Why do you need to know?
A DOI is required by some citation styles (APA, Chicago, MLA 8th ed.)


For more information visit, the Digital Object Identifier System.

  2. In the pop-up bar on the right, click the blue Add more fields... button at the bottom to add DOI or any other information.
