Leiden University

Leiden University (Universiteit Leiden) is the oldest university in the Netherlands, founded in 1575, and ranks #141 in the QS World University Rankings 2025. Its public, machine-accessible developer footprint is modest and centered on its libraries rather than a central developer portal. Leiden University Libraries operates an OAI-PMH metadata harvesting endpoint for its Scholarly Publications repository and maintains an active open-source GitHub organization (LeidenUniversityLibrary) with library, Islandora, and IIIF tooling. There is no centrally documented public REST API program; most institutional and student systems are gated behind SSO.
