DTU Findit — library discovery
DTU Library's discovery interface, running on DTU's own host on the open-source Blacklight stack rather than on a vendor SaaS domain. It publishes an OpenSearch 1.1 description document that resolves openly. Catalog responses themselves sit behind a verification interstitial for non-browser clients, so it is a real but only partially machine-readable surface. No vendor contract is saved under DTU for it.
