Free doi registration for journal

A digital object identifier provider for journal articles

Registering a DOI (Digital Object Identifier) with doi engine provides two free doi numbers. DOI registration agencies play a crucial role in ensuring the persistence and reliability of DOI links and metadata, which requires infrastructure and resources, and this is often reflected in the fees they charge. However, some organizations, particularly academic institutions, may have agreements with DOI registration agencies that allow researchers affiliated with those institutions to register DOIs at reduced or no cost. Additionally, some repositories and journals may cover the cost of DOI registration for the content they publish.
