A DOI is a Digital Object Identifier. It is the shortened form of a URL that will permanently point to an article. For example, if article X’s DOI is ab/12.345, the URL https://doi.org/ab/12.345 will always point to article X, even if the journal eventually changes its internet address. DOIs are the preferred form of URL, if they are available.

For more information on DOIs, see the website of the International DOI Foundation.
