The archives are split into two parts. One part includes the papers, publications and publicity documenting the organizational history—its governance, policies and strategic planning—and all its artistic and outreach programming. In addition the collections include photographs, video and audio, publications and personal correspondence with more than 450 artists and curators. A large portion of this information is housed at the Historical Society of Pennsylvania.
The archives also includes the permanent collection of more than 1,400-original prints, collages and other works on paper.
