Q. What is a Digital Object Identifier (DOI)?

answer

Answer

A Digital Object Identifier (DOI) is a unique and persistent identifier which provides a link to an object on the Internet via a registration and indexing service.

DOIs are often used in citations and discovery services to provide permanent links to online articles, eBooks, images, reports, and other types of digital objects.  The DOI acts as a pointer to the actual location of the item.

DOIs can be converted into URLs to link to the referenced item.

To learn more, see the Digital Object Identifier (DOI) guide.
