Carlson Library Map Collection

The Map Collection is located on the east side of the third floor of Carlson Library and consists of sheet maps and atlases. These maps are for reference use, and therefore do not circulate. However, exceptions may be made for items to be used briefly in the classroom or for projects of short duration.

Maps are arranged by Library of Congress classification numbers. Atlases are on stands in the Collection.

Most of the collection consists of topographic maps (showing contours and elevation) for the Great Lakes states (Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania, and Wisconsin, as well at the Canadian province of Ontario) from the United States Geological Survey. These are arranged in drawers by call numbers that group states by geographic region, with the maps filed alphabetically by quadrangle name.  An index is included in each drawer.
