On April 7, 1805, Meriwether Lewis and William Clark left Fort Mandan for points west, beginning the process of "filling in the canvas" of America. This exhibition features the Library's rich collections of exploration material documenting the quest to connect the East and the West by means of a waterway passage.

Presidents Andrew Jackson, James Polk, and John Tyler, like many Americans of this time, embraced the notion of enlarging the "empire for liberty." In other words they wanted to expand the borders of America westward.

The Railroad maps represent an important historical record, illustrating the growth of travel and settlement as well as the development of industry and agriculture in the United States.

Over 30,000 photographs, drawn from the holdings of the Western History and Genealogy Department at Denver Public Library, illuminate many aspects of the history of the American West. Most of the photographs were taken between 1860 and 1920. They illustrate Colorado towns and landscape, document the place of mining in the history of Colorado and the West, and show the lives of Native Americans from more than forty tribes living west of the Mississippi River.
