DOI

A DOI, or Digital Object Identifier, is a unique alphanumeric code assigned to digital documents like research articles, datasets, or reports. Think of it as a permanent online address that ensures the item can always be found, even if its location on the internet changes. When you use a DOI link, it directs you straight to the specific resource. This system helps researchers, students, and professionals access and cite digital content consistently and reliably, maintaining the integrity of digital records over time.
