The Frick Art Reference Library's Photoarchive is a study collection of more than one million photographic reproductions of works of art from the fourth to the mid-twentieth century by artists trained in the Western tradition. The Photoarchive was founded first and foremost to facilitate object-oriented research; the documentation it offers traces the essential elements of the biography of the work of art — changes of attribution, ownership, and condition. The images, together with the historical information, provide an unparalleled resource for the study of the history of art.
The Center for Creative Photography is an archive and research center located on the University of Arizona campus. It retains the archives of Ansel Adams, Edward Weston, Garry Winogrand, Harry Callahan, and other great twentieth-century photographers. The Center is pleased to announce that its collections of photographs by Edward Weston and Ansel Adams are now available on the University of Arizona Institutional Repository.
