The BFPB database (Clavius system) currently contains only abbreviated records of 18th-century printed material allowing combined searches by author, title, printer/publisher, year and place of issue. Linked to the records are digitized cards with detailed bibliographical descriptions and a list of extant copies. the BFPB database will gradually be expanded with records of works for which no extant copy is yet known (known as desiderata), and analytical descriptions of publications not yet recorded in the original BFPB card catalogue. In view of contemporary developments abroad in the area of granting access to national retrospective bibliographies, from 2014 the BFPB database will be systematically supplemented by digital copies of the described publications, which together with detailed selection data will significantly improve the convenience of research and the utilization of the processed documents.
