McKeldin Map Collection

Guide to the map collection on the 4th floor of McKeldin Library.

In McKeldin

The topographic maps are filed by scale, then alphabetically by state or territory name, then by map/quadrangle name.  An index to find quadrangle names is on the top of the cases, or you can use the USGS Store to find a quadrangle name (as well as a scanned GeoPDF).

Our holdings are:

USGS Topographic Maps

Topographic maps depict both natural features--mountains, valleys, plains, lakes, rivers, vegetation--and artifacts of human development and civilization. Streets, roads and railroads, political and administrative boundaries, transmission lines, buildings, dams, parks, airports, mines, and levees may all appear on topographic maps. They are therefore useful for a wide range of applications, including land use planning, agriculture, engineering, development, conservation, recreation, and historical research.

As of 2010, the USGS no longer publishes print copies of topographic maps.  You must print your own or order them on demand from USGS.  Newer topographic maps are digital GeoPDFs and are called US Topo.
