The USGS serves the Nation by providing reliable scientific information to describe and understand the Earth; minimize loss of life and property from natural disasters; manage water, biological, energy, and mineral resources; and enhance and protect our quality of life. The USGS also has an online, searchable library. Its library is the largest library for earth sciences in the world. The library system includes four libraries and is part of the Geographic Information Office of the USGS. Another important resource is the USGS Photographic Library, which offers access to more than 30,000 color and black-and-white photographs taken during geologic studies of the U.S.  These images provide a visual history of the discovery, development, and sciences of the United States and its Geological Survey. Some photographs have been used in USGS publications, but most have never been published.
