DigiVatLib is a digital library service providing free access to the Vatican Library’s digitized collections: manuscripts, incunabula, archival materials and inventories as well as graphic materials, coins and medals, and printed materials (special projects).

DigiVatLib is based on the International Image Interoperability Framework (IIIF) technology. This technology allows researchers to compare digital objects from DigiVatLib with digital material from other IIIF repositories. Descriptions and bibliographic references from DigiVatLib’s online catalogues are indexed and linked to digital materials. OPACs provide access to the Vatican Library's collections. The set of the online catalouges includes archives, manuscripts, coins and medals, printed materials as well as special catalogues (incunabula, visual materials) and a general catalogue able to search on any holdings.

In 2010, the Vatican Library began digitizing its 80,000 manuscripts (excluding archival materials). Incunabula and Greek, Hebrew, and Latin manuscripts were digitized as part of the Polonsky Foundation Digitization Project.
