More than two million scholarly articles aren't being archived

"More than two million scholarly articles are not being properly archived according to a new analysis.

A study published in the Journal of Librarianship and Scholarly Communication in January reviewed more than seven million documents with digital object identifiers (DOIs). The DOIs are unique identifiers given to most—but not all—scholarly articles, acting as a digital fingerprint.

Of the 7,438,037 articles, roughly 28 percent, or more than two million works, did not appear in the reviewed archives despite having a DOI. A little more than half the works (4.3 million articles) were in more than one archive, according to the study.
