The GeoRef database, established by the American Geological Institute, covers the geology of North America from 1693 to the present and the geology of the rest of the world from 1933 to the present. The database includes references to all publications of the U.S. Geological Survey. The database contains over 2.6 million references to geoscience journal articles, books, maps, conference papers, reports and theses.

To perform the most comprehensive search, it is recommended that you select both GeoRef and GeoRef In Process. Contains bibliographic citations, some of which include abstracts, that are in the process of being indexed prior to their integration into the main GeoRef database. The bulk originate from non-English language geoscience literature that was not necessarily published recently.
