The Donald W. Hamer Center for Maps and Geospatial Information is Pennsylvania's regional Federal Deopsitory Library for maps distributed by the U.S. Government Publishing Office. This collection includes topographic maps of all 50 U.S. states. We have maps at several scales and time periods.
The collection also includes topographic maps for other countries. See the Other Countries tab in this guide for more information about how to find these maps.
We have digitized our 15 minute Pennsylvania maps.
