When the Civil War ended in 1865, more than four million slaves were set free. Over 70 years later, the memories of some 2,000 slave-era survivors were transcribed and preserved by the Library of Congress. These first-person anecdotes, ranging from the brutal to the bittersweet, have been brought to vivid life in this unique HBO documentary special, featuring the on-camera voices of over a dozen top African-American actors.

The documentary about the Library is C-SPAN’s original feature on America’s iconic government institutions and buildings. This in-depth examination of the Library takes an intimate look at the oldest U.S. federal cultural institution, providing a behind-the-scenes glimpse into the history of the world’s largest library and its vast collection of books, photographs, maps and manuscripts. The documentary also examines how the Library is using science and technology to protect the nearly 150 million items in its collections. The Library of Congress is the only library in the world with its own preservation-science laboratory. Founded in 1800, the Library of Congress is the nation’s oldest federal cultural institution. Many of the Library’s rich resources can be accessed through its website at www.loc.gov.
