UB Tübingen library catalogue (IBS|BW consortium tenant) is one of 8 APIs that [University of Tübingen](https://apis.io/providers/university-of-tubingen/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Library, Discovery, Catalog, Tenant, and IBS|BW.

The University Library's main catalogue and discovery interface. Verified 2026-09-01: https://katalog.ub.uni-tuebingen.de/ redirects (301) to https://rds-tue.ibs-bw.de/opac/, a Tübingen-scoped instance on the IBS|BW (Integriertes Bibliothekssystem Baden-Württemberg) consortium platform, which answers 403 to an anonymous non-browser client. The instance and its holdings are Tübingen's; the platform and its contract belong to the consortium and its library-systems vendor, so nothing is saved here. Its companion campus portal alma.uni-tuebingen.de serves a meta-refresh into /alma/rds?state=user — a login portal, no public API. Recorded as a tenant relationship, which is a real institutional fact.
