Library Sierra API (Innovative Interfaces) is one of 8 APIs that [University of Glasgow](https://apis.io/providers/university-of-glasgow/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Library, Library Catalog, and Integrated Library System. The published artifact set on APIs.io includes authentication docs.

The library management system's Sierra REST API, live on the University of Glasgow Library's own catalogue host. /iii/sierra-api/v6/info/token returned 401 on 2026-08-30 — present and credentialed rather than absent. Keys are issued by the library to named partners; there is no public registration path and no public documentation on gla.ac.uk. Recorded because a live credentialed endpoint is a finding, not a gap.
