Yale University Library Digital Collections IIIF is one of 13 APIs that [Yale University](https://apis.io/providers/yale/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include IIIF, Library, Digital Collections, Cultural Heritage, and Image. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

IIIF Presentation 3.0 manifests for Yale University Library's digitized collections. The service is institution-operated — the host resolves to an AWS load balancer in Yale's own account (alb-yul-dc-prod) and the entire stack is openly published by the yalelibrary GitHub organization (yul-dc-blacklight, yul-dc-management, yul-dc-iiif-imageserver). A manifest fetch returned 200 with 1.4 MB of IIIF Presentation 3.0 JSON on 2026-08-19. Note that Yale's robots.txt disallows /manifests/ for all user agents, and the Blacklight JSON surface at /catalog.json answers automated requests with an empty HTTP 202 edge challenge.
