A guide to obtaining information from the USGS 1978

For almost 100 years, the USGS (U.S. Geological Survey) has served Federal, State, and local governments and the public by collecting, analyzing, and publishing detailed information about the Nation 's mineral, land, and water resources. This information is released in a variety of map, book, and other formats and is available for free distribution or for sale from sources both within and outside the USGS. This guide has been prepared to assist in obtaining these information products and to aid in locating both general and specific unpublished information within the USGS. (Woodard-USGS)
