Stephen J. Bury, Andrew W. Mellon Chief Librarian, presents a group of maps, guides, photos, and other objects related to the Frick Art Reference Library’s involvement in cultural preservation during World War II. From July 1943 to January 1944, the institution closed to the public to serve as the headquarters of the Committee on the Protection of Cultural Treasures in War Areas, part of the so-called Monuments Men program—a rare but pivotal time the library’s century-long history intersected with major world events.
