The Packard Campus of the National Audio-Visual Conservation Center is a state-of-the-art facility where the Library of Congress acquires, preserves and provides access to the world’s largest and most comprehensive collection of films, television programs, radio broadcasts, and sound recordings. The Campus has globally unprecedented capabilities and capacities for the preservation of all audiovisual media formats including obsolete formats dating back more than 125 years. In addition to preserving the collections of the Library, the Packard Campus was also designed to provide similar preservation services for other archives and libraries in both the public and private sector. The Packard Campus was constructed through a unique partnership between the Packard Humanities Institute and the Library of Congress. The Packard Institute’s gift to the nation of the finished campus is the largest private-sector donation ever made to the Library of Congress.
