The Westward expansion is the primary focus of a recent Library exhibition, "Rivers, Edens, Empires: Lewis & Clark and the Revealing of America," which presents a century of exploration that features the expedition of the Corps of Discovery as the culminating moment in the quest to connect North America by means of a waterway passage. Thomas Jefferson sent Merriweather Lewis and William Clark into the West, and he patterned their mission on the scientific methods of the Enlightenment: to observe, collect, document and classify.
The extraordinary legacy of Jefferson is also explored in the eponymous
exhibition, which documents his roles as founding father, farmer, architect, inventor, slaveholder, book collector, scholar, diplomat and third president of the United States.
