DOI system

The DOI (Digital Object Identifier) system provides a permanent, unique identifier for digital content like journal articles, research papers, or datasets. Unlike URLs that can change over time, a DOI stays constant and always directs you to the current location of the content. It functions like a digital license plate, enabling reliable and efficient access, citation, and management of digital resources. Managed by organizations like CrossRef, the DOI system improves discoverability and ensures persistent links to scholarly and professional materials across the internet.
