The Missouri Historical Society was founded in 1866, and since that time has been collecting published and manuscript materials focusing on the history of St. Louis, the state of Missouri, and the nineteenth-century American West. The collections include notable holdings regarding the colonial and territorial periods, the American fur trade, western travel and exploration, steamboats and river transportation in the Mississippi Valley, the Civil War, and the 1904 St. Louis World's Fair. Much of the library's catalog is now accessible online at the website. In addition, the library's on-site 'Information File' indexes numerous local published sources, and the Archives Card Catalog indexes the manuscript collections.
