Crossref Membership (eleven faculty and institute member records) is one of 10 APIs that [Chulalongkorn University](https://apis.io/providers/chulalongkorn/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include DOI, Persistent Identifiers, Scholarly Publishing, and Registry.

Chulalongkorn registers Crossref DOIs through eleven separate member records, one per faculty, institute or office, each with its own prefix — Engineering 10.4186, Medicine 10.5372, Architecture 10.54028, Economics 10.65681, Political Science 10.61462, Fine and Applied Arts 10.56841, the Language Institute 10.66947, the Sustainable Environment Research Institute 10.35762, the Metallurgy and Materials Science Research Institute 10.55713, and the Office of Academic Resources twice (10.58837 and 10.56808, the latter explicitly for its Digital Commons journals). The fragmentation is the finding: the university is a federation of buyers even in its own identifier registration.
