Paul V. Galvin Library is a participant in the Federal Depository Library Program, and as such, receives 7.5 minutes topographic maps of the United States from the United States Geological Survey. The depository is receiving electronic versions of these maps, which are distributed in GeoPDF format. These new maps can be searched for in the online catalog of the library's holdings available on the library homepage.
Current editions of maps that were originally distributed to depositories in paper format have been digitized as normal PDF. These and the newer editions, in Geo PDF format, are available for download from the USGS Map Locator, below.
