A Digital Object Identifier is a persistent alphanumeric string that provides a permanent link to digital content. DOIs ensure long-term accessibility and proper citation of scholarly works regardless of changes in web addresses.

Full Definition

A Digital Object Identifier (DOI) is a standardized persistent identifier system used to uniquely identify digital objects, particularly scholarly publications, datasets, and other academic content. Managed by the International DOI Foundation through registration agencies like Crossref, DOIs provide permanent, reliable links that redirect to current locations of digital content even if URLs change. This system is essential for maintaining the integrity of scholarly communication and ensuring proper attribution in academic libraries.

Plain English

A special web address that always works to find a specific research article or document, even if the regular website address changes.
