Oh, happy day! The Library of Congress YouTube Channel is officially open!
Timeless treasures and contemporary presentations from the Library of Congress in Washington, D.C. As the world’s preeminent reservoir of knowledge, we are the steward of millions of recordings dating from the earliest Edison films to the present. In addition, we sponsor events, lectures and concerts that are free and open to the public. More about the Library: http://www.loc.gov/about
