The National Audio-Visual Conservation Center (NAVCC) is a branch of the Library of Congress devoted to preserving the United States' audio-visual history. It includes the Packard Campus (PCAVC), opened in 2007 to store the then entire 6.3 million piece collection of the Library's movie, television, and sound artifacts, the Center's largest facility; the Library's Motion Picture and Television Division and Recorded Sound Division reference centers on Capitol Hill; the Mary Pickford Theater; and any other Library of Congress audio-visual storage facilities that remain outside the Packard Campus audiovisual archive located inside Mount Pony in Culpeper, Virginia.
