The U.S. Library of Congress's exhibition, "The Books That Shaped America," in Washington D.C. from June 25 to September 29, 2012. The books include the McGuffey Readers, schoolbooksthat educated people like Henry Ford at the turn of the century, to Walt Whitman, Thoreau, Edgar Rice Burroughs, Ray Bradbury and Dr. Seuss. Even Dale Carnegie. It includes social issue books by Upton Sinclair, Ida Tarbell, W.E.B. Du Bois, Cesar Chavez. Literary works include Emily Dickinson, Thornton Wilder and Tennessee WIlliams. Carl Sagan's book on astronomy doesn't appear on this list. It is a pretty impressive list and a valiant effort to cover the American experience through books that most Americans are familiar with from school or other reading, and books that have conveyed a sense of America in all its struggles and humanity to people in other countries and especially the English speaking world.
