The Clark library has an extensive collection of auction catalogs going back to the mid-19th century. A considerable portion of the early catalogs were part of the library of the Duveen Brothers Firm, acquired by the library in 1964. Many of the Duveen Library catalogs include agents' annotations of prices and buyer's names; such catalogs are rich sources of provenance information that is often not available from any other source.
