My first visit to Washington DC was New Years Eve, 1974. Then and in numerous visits since, I had never been to the the Library of Congress. Sure, I had seen views captured in movies, such as National Treasure. This time I attended an event in the newer Madison Building and later received a tour of the Jefferson Building.
 
Don't repeat my mistake, visit the first opportunity you receive. There is so much history in the buildings and the collections that you wouldn't want to miss the chance to experience it for yourself.
 

The Library of Congress Great Hall: some members of the Garland delegation can be seen on the lower level. There is history in every inch of this picture. The Library was one of the first buildings to be lit with electric bulbs. They were such a novelty, no one thought to hide them behind shades, so they are still today clearly visible.
