This collection supplements and enhances the printed copies in the Library of Congress general collections. These catalogs contain
annotations about prices and buyers names obtained by the Knoedler Library staff members who were present at the auctions. Newspaper clippings relating to the artist, collector or the sale itself have been placed in many catalogs. The catalogs are grouped by country, and then chronologically by date of sale. These catalogs are primarily American and French from the nineteenth and twentieth centuries.

"A unique and heavily used collection in the New York Public Library's Division of Art, Prints, and Photographs. Sources for biographical information, these files, begun in 1911, were created for the use of the art reference collections. They include material on painters, architects, sculptors, art historians, collectors, connoisseurs, silversmiths, jewelers, furniture and interior designers, handicraftsmen, commercial artists, and couturiers. The contents of the files include exhibition brochures, small exhibition catalogs, gallery announcements, and other detached ephemera"--The Library of Congress Guide to the Microform Collections in the Humanities and Social Sciences Division, online version.
