The federal government is a major publisher of geology reports and publications. Below are resources produced by the U.S. Geological Survey (USGS). Most of these resources are indexed in GeoRef [CSA-Web]. USGS publications can be shelved either in the Library's General Collection (Stacks), for older materials, or the Library's Government Documents collection, for newer materials. Many publications are also electronically accessible, and the online catalog will often reflect this. Be sure to contact the Geology liaison, Ed Gonzalez, if you need assistance in locating materials. Note: this is not an exhaustive listing of USGS publications available at University Library.
