Digital Rare Book Collections

The University of Illinois Digital Rare Book Collection is a diverse collection of imprints from our special collections libraries generated through scholar requests, for preservation purposes, or as part of digital humanities projects in progress. Please bear in mind that many other rare items are digitized and are accessible in subject-oriented collections within Illinois Harvest or via a link in the online catalog record.

RBML selects rare books for digitization and prioritizes their project queue. DCC digitizes content for selected ongoing projects weekly. Ongoing and past collectiosn include Ise Mongotari, the Emblematica collection and the Cavagna colletion.
