The Miriam and Ira D. Wallach Division of Art, Prints and Photographs: Photography Collection

The Photography Collection was created in 1980, when images culled from other NYPL departments and branches were brought together to form a new division that now comprises approximately 500,000 photographs by 6,000 photographers. The Photography Collection encompasses the broadest range of the medium, including images made for commercial, industrial, and scientific application as well as images for the press and other print media, the vernacular of amateur snapshot photography and original works intended for exhibition and/or the art market.
