DOI (Digital Object Identifier)

A Digital Object Identifier (DOI) is a permanent, unique code assigned to digital content like research articles, datasets, or reports. It functions like a digital fingerprint, ensuring that the item can always be reliably found and cited, even if its web address changes. When you use a DOI link, it directs you to the current location of the content, making it a valuable tool for stable referencing in academic and professional contexts. Essentially, DOIs help maintain consistent access and proper attribution for digital resources over time.
