Today’s Library of Congress is not only the repository of the nation’s life story, it’s arguably the “ultimate museum,” documenting civilizations from around the world. This program immerses viewers in history through a selection of cultural treasures archived among the library’s more than 130 million items, including Jefferson’s draft of the Declaration of Independence, the maps carried by Lewis and Clark, and the typewritten script of Martin Luther King’s “I Have a Dream” speech. A viewable/printable educator’s guide is available online. (27 minutes)
