US Geological Survey Maps

The USGS is the largest map publisher in the government. In addition to numerous subject maps, the USGS produces sets of topographic maps.

Topographic Maps

A topographic map series is a group of sheets that depict physical and cultural detail. Our sets of topographic maps are shelved by Library of Congress call number, then alphabetically by the name of the sheet. To determine the specific sheet you need in a series, you will need to use the individual index for that set. Usually one copy of the index will be in the map cases with the set of maps.

Cofrin Library (UW-Green Bay campus) has Wisconsin topographic maps, and they can be found in Search@UW.

Other catalogs to help you choose topographic maps  include:

Other USGS Maps

In addition to topographic maps, the USGS also issues many different subject series of maps, individual maps on various topics, and numerous printed reports that contain extensive maps. 

The different sets of USGS subject maps such as the Hydrologic Investigations Atlases (HA) series, or the Geologic Quadrangle (GQ) series are stored folded and in brown envelopes, and are kept in the filing cabinets surrounding the map cases on 5th floor. They are arranged alphabetically by their series designation (EX: HA) and map number.
