The online MBK Database documents the state of research and edition work on medieval library catalogues in Germany and Switzerland, containing information on the origins and contents of the catalogues, the date and transmission of the sources, edition and research publications, and links to digital publications and online resources.

The online manuscript catalogue is a complete record of all manuscripts and early prints referred to in the previously published MBK volumes. Of particular interest are the manuscripts and other documents that are not themselves edited but are identified as belonging to the original book collections or simply mentioned in the historical introduction. The manuscript catalogue indexes all such material with references and signatures, making it searchable for research purposes.

The printed editions of Mittelalterliche Bibliothekskataloge Deutschlands und der Schweiz with the supplementary volumes (Ergänzungsbände) are now available online in PDF format
