The database provides access to full texts of international auction catalogues published between 1600 and 1900. Approx. 35,000 titles are planned to be digitized. Electronic fulltexts are based on filmed versions of holdings from diverse libraries, among others the Rijksbureau voor Kunsthistorische Documentatie (RKD), The Hague; the Rijksmuseum, Amsterdam; the National Art Library, Victoria and Albert Museum, London; the Courtauld Institute, London.

Designed for the digital world and an expanding universe of metadata users, "RDA: Resource Description and Access" is the new, unified cataloging standard. The online RDA Toolkit is the most effective way to interact with the new standard.
