From the Library of Congress in Washington, DC. Hello, I'm David McCullough. My life's work is rooted in researching and writing about history. My most recent book is about the amazing Wright Brothers who taught the world how to fly. And I did that research here in the Library of Congress. I'll have the opportunity to talk about my book and meet my readers at the Library of Congress National Book Festival at the Walter E. Washington Convention Center in Washington, DC on Saturday, Sept. 5. The festival is from 10am to 10pm and admission is free. This popular celebration of authors and readers will mark a double anniversary in 2015. It's the 15th year of the book festival and the event will also celebrate 200 years since the Library acquired Thomas Jefferson's personal library. It's appropriate that this year's theme is "I Cannot Live Without Books," Jefferson's famous statement in a letter to John Adams after he sold his personal book collection to the Library of Congress. His collection replaced the books destroyed by fire when the British attacked the U.S. Capitol in 1814. That's a little history lesson. Join me at the National Book Festival on Sept. 5 to learn more about history, reading and books. This has been a presentation of the Library of Congress. Visit us at loc.gov.
