Many of the State Historical Society’s holdings are included in Merlin, the shared library catalog of the four University of Missouri campuses. The State Historical Society holds numerous books on the history and study of travel in Missouri, the Midwest, and the United States. The broadest term to search is the subject term "travel" or the specific author of any work. For a more specific search in Missouri, simply add the subject term "Missouri" to your search.
For more information on the geography, location, and routes of travel see the State Historical Society of Missouri’s map collection and digital map collection. The collection contains maps dating to the early 1700s. The maps deal primarily with the development and changing boundaries of Missouri and the Louisiana Purchase.
The State Historical Society’s Historic Missourians website has entire categories devoted to explorers and settlers and travelers in Missouri. Each biography includes images, primary resources, and other references for further study.
