James Conaway centers this history around the thirteen men who have been appointed by presidents to lead the Library of Congress. The author investigates how the Librarians' experiences and contributions, as well as the Library's collections, have reflected political and intellectual developments in the United States. Each Librarian confronted great challenges: the entire Library collection was lost when the British burned the Capitol in 1814; in the 1940s, a backlog of one and a half million objects waited to be catalogued; the gigantic task of replacing the card catalogue with a computerized system was undertaken in the 1980s. Yet each Librarian also enjoyed the excitement of acquiring unique treasures -- from Walt Whitman's walking stick to the papers of the Wright brothers, from the Civil War photographs of Mathew Brady to the archives of Leonard Bernstein. This lively account of the Library of Congress and those who guided its progress over two centuries is the history ofan American institution that today is truly a library to the world, serving readers and researchers everywhere.
