As we continue to celebrate the Frick Art Reference Library’s one-hundredth anniversary, Kerri A. Pfister, Photoarchivist, guides us through the library’s collections of reproductions, which have enabled the widespread study of art history. From printmaking to photography to digital imagery, the library has offered cutting-edge technologies through the ages to fulfill its mission of making art resources accessible to the public. Objects featured in this post are part of the celebratory publication One Hundred Objects in the Frick Art Reference Library, available in the Frick’s shop.
