Princeton University Library Catalog (Orangelight) is one of 14 APIs that [Princeton University](https://apis.io/providers/princeton/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Library, Catalog, Discovery, Blacklight, and JSON. The published artifact set on APIs.io includes API documentation and a GitHub repository.

Princeton's library catalog at catalog.princeton.edu, a Blacklight application the Library writes and maintains itself as pulibrary/orangelight. Every route answers to a .json suffix, so catalog.princeton.edu/catalog.json is an unauthenticated search API returning a JSON:API-shaped envelope with self/next/last/prev links, facets and full record documents. Records carry Alma MMS IDs; the underlying library system is an Ex Libris tenancy, but this contract and this application are Princeton's own code.
