Digital Library Collections and the 10.7916 DOI namespace is one of 10 APIs that [Columbia University](https://apis.io/providers/columbia/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Digital Collections, DOI, DataCite, Crossref, and Persistent Identifiers.

Columbia University Libraries' digital collections platform and the resolution target for Columbia's own DOI namespace. Columbia is a registered DataCite repository client (CUL.COLUMBIA, active since 2018) minting under prefix 10.7916, with 1,111,628 DOIs registered at probe time, resolving to dlc.library.columbia.edu. It is Columbia's own persistent-identifier infrastructure — only the registry is DataCite's. Columbia University Libraries separately deposits into Crossref as member 6984. The platform serves HTML; no IIIF manifest endpoint or JSON API was reachable, and iiif.library.columbia.edu does not resolve.
