UC Berkeley Library GeoData (GeoBlacklight) Catalog API is one of 8 APIs that [University of California, Berkeley](https://apis.io/providers/ucb/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Open Data, Geospatial Data, Library, Discovery, and GeoBlacklight.

The UC Berkeley Library's GIS and map discovery application, built and hosted by the Library itself (the application source is public at BerkeleyLibrary/geodata and the host resolves inside Berkeley's own network to nginx-prod.lib.berkeley.edu). Its Blacklight JSON interface answers anonymous requests at /catalog.json with a paginated JSON:API-shaped response over 5,156 geospatial dataset records described in OpenGeoMetadata Aardvark fields. This is the only Berkeley-operated API that returns institutional data to a caller with no credentials at all. No OpenAPI is published for it and none was generated.
