Digital Object Identifier

A Digital Object Identifier (DOI) is a unique, permanent code assigned to digital content like research papers, articles, or datasets. Think of it as a digital "name tag" that always points to the specific item, even if its online location changes. This ensures reliable citation and easy access over time. Instead of relying solely on a URL that might break or change, a DOI provides a direct, stable link, helping researchers, students, and professionals consistently find and reference digital resources accurately.
