In part three of Books That Shaped America, Stephenie Ambrose Tubbs explored the [Journals of Meriwether Lewis and William Clark], which were published in 1814 and recorded the 1804-1806 expedition they led through the western United States following the Louisiana Purchase. Tubbs is the author of [The Lewis and Clark Companion]. The program includes: a Library of Congress curator talking about and showing an 1803 map that Lewis and Clark took with them as well as the map they made in 1805 of their trip; a short video tour of the Lewis and Clark Boat House and Museum in St. Charles, Missouri; and comments from a middle school teacher in Iowa, who described how she teaches Lewis and Clark. Books That Shaped America is a 10-part series, created in partnership with the Library of Congress, that examines major works of literature that have had a significant impact on the country and public policy.
