The core collections preserved in the archives at Jacob's Pillow were originally assembled by founder Ted Shawn. Materials have been continually added since the 1930s by volunteers from the Pillow Board and staff. In 1991, Jacob's Pillow created the position of Director of Preservation to direct the activities and maintenance of the Archives. The Archives at Jacob's Pillow has approximately 6,000 films and videos from 1894 to present, 45,000 historic dance photos and negatives, 313,000 pages of unique printed materials, 27 trunks of costumes dating from 1915, and 2,000 books. The Archives is one component of the Pillow's Preservation Program, which organizes exhibits exploring various aspects of dance, oversees issues concerning the National Historic Landmark site, and records the ongoing activities of the Festival.
