University of Twente Library Crossref Membership

The University Library registers DOIs with Crossref in the university's own name. Crossref member 2372, "University Library/University of Twente", located AE Enschede, Netherlands, holding DOI prefix 10.3990 with 599 member DOIs (23 current, 576 backfile) and 5,393 works resolvable under the prefix. This is an institution-operated identifier surface and a fact about the university, not a contract it publishes — the Crossref REST API belongs to Crossref. The university is also registered in ROR as https://ror.org/006hf6230 with domain utwente.nl and established date 1961. It is deliberately NOT recorded as a DataCite member: api.datacite.org returns zero clients and zero providers for the university, and its research-data DOIs are minted under prefix 10.4121 by 4TU.ResearchData, which TU Delft operates.
