The Packard Humanities Institute (PHI) is a non-profit foundation, established in 1987, and located in Los Altos, California, which funds projects in a wide range of conservation concerns in the fields of archaeology, music, film preservation, and historic conservation, plus Greek epigraphy,[2] with an aim to create tools for basic research in the Humanities.

In 1997 with the approval of the United States Congress the David and Lucile Packard Foundation purchased the former high-security storage facility operated by the Federal Reserve Board.

The Packard Campus is the site where the nation's library acquires, preserves and provides access to the world's largest and most comprehensive collection of motion pictures, television programs, radio broadcasts and sound recordings.

Opened in 2014, Packard Humanities Institute in Santa Clarita, California has film vaults for media preservation.

PHI Santa Clarita also holds and is transferring the Hearst Metrotone News collection, newsreels made from 1915 to 1975, on a Scanity motion picture film scanner.
