Welcome to the USGS Library! Authorized by Congress in 1879, the U.S Geological Survey Library is recognized as one of the world's largest Earth and natural science libraries, providing services, collections, and expertise that are essential to the USGS mission and the global geoscience community. The USGS Library is a multisite, centralized library, providing bureau-wide access to scholarly journals and research support services to USGS employees around the nation.
