Teitelman collection and the Oliver Radford collection, both collections of architectural photographs not held anywhere else. As well as the Arthur Wright Collection of photographs from a scholar's trips to China during the 1950s-1970s.

Wesleyan University Library is a contributor to the Fragmentarium, a digital repository for manuscript fragmentology and related studies. We contribute all digitized fragments to this repository in addition to our own to further enable scholarly research. On Fragmentarium, researchers can catalogue, contextualize, describe, and transcribe manuscript fragments; as well as virtually reconstruct the manuscripts as they were before fragmentation.
