Part of the California Environmental Resources Evaluation System (CERES). “CERES, in partnership with the USGS National Biological Information Infrastructure, is developing a thematic thesaurus for use in cataloging and searching for environmental information. Browsing and searching software and a thesaurus-database networking specification are being developed which will make it possible to allow users to locate and utilize controlled vocabulary terms from multiple networked thesaurus databases, including the USGS's Integrated Taxonomic Information System of species names (ITIS). The CERES/BRD thesaurus, the software, and specifications for networking thesauri will be made available for use by other information cataloging and retrieval programs.”
