iDAI.bibliography/ZENON is the central indexing system for our 16 libraries and all our publications. With approximately 1.4 million records, it is one of the world's most important bibliographic reference tools for the literature of Classical Studies. At the same time, iDAI.bibliography also indexes digitised prints from the 16th to 19th centuries, digitised journals and open access publications in Classics. Increasingly, specialist literature without an inventory record is also included, for example as a bibliographic record for networking with the iDAI.world systems.

The publication platform iDAI.publications is an important component of the DAI's digital research landscape, iDAI.world. It provides free worldwide access to our online journals and the digital editions of a large number of DAI journals, monographs, serials and edited volumes.
