The GeoRef database, established by the American Geological Institute (AGI) in 1966, provides access to the geoscience literature of the world. GeoRef is the most comprehensive AGI database in the geosciences and continues to grow by more than 100,000 references a year. The database contains over 3 million references to geoscience journal articles, books, maps, conference papers, reports and theses.
The GeoRef database includes references to all publications of the U.S. Geological Survey. Masters' theses and doctoral dissertations from US and Canadian universities are also covered.
To maintain the database, GeoRef editor/indexers regularly scan more than 3,500 journals in 40 languages as well as new books, maps, and reports. They record the bibliographic data for each document and assign index terms to describe it. Each month between 4,000 and 7,000 new references are added to the database.
ProQuest Deep Indexing: Earth Sciences supplements GeoRef with access to deep indexing for tables, figures, graphs, charts and other illustrations from the scholarly research and technical literature for selected records. Records from the database appear with searches of GeoRef to provide an additional path for discovery.
Major areas of coverage include
1669 - present (North America coverage); 1933 - present (Worldwide coverage)
