AGI enjoys an excellent reputation for GeoRef, the most comprehensive bibliographic database in the geosciences. For thirty years, AGI has continuously updated the GeoRef database, which currently includes 2.2 million references. The GSC database is produced by the same staff, and indexing and format follow the same conventions used in production of GeoRef. This release of the GSC includes over 60,000 references to documents published since 1975. Over 1,000 new references will be added in each quarterly update.
Coverage is worldwide, with emphasis on the United States.
Journal articles, books, conference proceedings, theses and dissertations are included. Also covered are all relevant reports of the U.S. Geological Survey, and reports of the U.S. Departments of Energy, Defense, Health and Human Services, and the Interior, and the Environmental Protection Agency. References contain complete bibliographic information. Thorough indexing, based on the controlled vocabulary found in the GeoRef Thesaurus, is included. Specific geographic locations are listed as place names and, for principal locations, latitude and longitude coordinates are provided.
