The USGS Enterprise Web Thesaurus is a tool to provide better access to U.S. Geological Survey science information. This database gives a controlled list of subject terms used for tagging USGS information resources to allow searching from a formal index. The thesaurus is limited in depth and specificity of coverage. It does not attempt to replicate existing controlled vocabularies, such as GeoRef. The intention is to provide a set of controlled vocabulary terms to be used as an additional searching tool along with free-text searching, framework organizations, and the use of other terminologies, taxonomies, and categories.
