Maps

 

We house a large collection of printed and manuscript maps, including historical U.S. Geological Survey topographic maps, initial township plats and homesteads of the U.S. Surveyor General, Sanborn Fire Insurance maps, railroad right‑of‑way maps, mining maps, blueprints, and other types of maps. Patrons can find maps in our library catalog and view them in our Reference Room.
