SCIPIO is the only database of online art and rare auction catalogues in the world. It covers sales catalogues from the late 16th century to the currently scheduled but not yet held auctions, with more than 440,000 records. Each record contains the date and place of sale, the title of the catalogue, the auction house, the seller, and the library that owns the collection. SCIPIO provides major auction houses in North America and Europe, as well as many privately-sold auction catalogues. It is an invaluable source of information for understanding artworks, treasures, history of collections, and trends in the past and present. The database is updated daily.
