A DOI (Digital Object Identifier) is a unique string of numbers and letters that is used to identify articles, books, images and any intellectual information found electronically. DOIs are assigned to articles when they are published and available electronically. DOIs can be used to help find an article easier. 

Since DOIs are more permanent than urls or web addresses, citation formats (for example, APA) prefer them over urls. 

Here are some examples of DOIs: 

  • DOI: 10.1080/02626667.2018.1560449
