author
A scientific agency rather than an individual author, this name represents the U.S. Geological Survey, the federal organization behind generations of maps, earth science reports, and research on natural hazards and resources. Its publications are shaped by a long mission to help people understand the land, water, ecosystems, and geology of the United States.

Created by Congress in 1879, the U.S. Geological Survey is the science bureau of the Department of the Interior. It was originally charged with classifying public lands and studying the nation's geological structure and mineral resources, and over time its work expanded far beyond geology alone.
Today, USGS scientists and specialists work across geology, hydrology, biology, geography, mapping, and natural hazards. The agency is especially well known for topographic maps, earthquake monitoring, water data, and research that supports public safety and decisions about land, energy, minerals, and ecosystems.
When a book lists Geological Survey (U.S.) as the author, it usually means the work was produced by this institution as part of its public mission. In that sense, the "author" is a long-running team of researchers, cartographers, and government scientists whose publications are meant to be practical, trustworthy, and widely useful.
