A DOI (Digital Object Identifier) is used to identify documents, such as journal articles, on the Web. Unlike an ordinary web address, a DOI does not change, but always points to the article even if the web address is altered.
Most major scholarly publishers assign their articles, and often other publications, a DOI. DOI information is usually found on the abstract page or in the header or footer of the publication. A DOI looks similar to this: 10.1136/ard.2007.085852.
By entering the publication's DOI in DiVA, you make it easier for others to find it. DOIs are also useful for bibliometric analyses.
