KKL-JNF's Photo Archive – part of the Department of Publications and Audio-Visual Aids, the Division of Communications and Public Affairs – was set up in 1920. It houses a treasure of some 180,000 prints and slides in color and black-and-white. It captures 100 years of photography: from the start of the 20th century to the present. Serving a broad public of scholars and professionals, it preserves rare and unique pictures, some of which were taken by leading photographers of the day. Since the Archives' establishment, its resources have been widely utilized in publications and exhibitions in Israel and abroad.
