Cambridge Digital Library IIIF APIs

The Cambridge University Library digital collections platform exposes IIIF Presentation API 2.1 manifests at cudl.lib.cam.ac.uk/iiif/ and IIIF Image API 2.1 endpoints at images.lib.cam.ac.uk/iiif/.jp2/info.json, both on the institution's own domain. Verified live: the manifest for MS-ADD-03996 (Newton's Trinity College Notebook) returns 247KB of application/json declaring @type sc:Manifest against the IIIF presentation/2 context, and the matching info.json returns application/ld+json with the image/2 context, tile sizes and scale factors. A supporting metadata service at services.cudl.lib.cam.ac.uk serves TEI XML per item. Institution-built and institution-operated — not a vendor discovery layer.
