The GeoRef database 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. Master's theses and doctoral dissertations from US and Canadian universities are also covered. The database contains references to geoscience journal articles, books, maps, conference papers, reports and theses.
This database contains records that are, literally, in the process of being indexed prior to their integration in the main GeoRef database. The majority of the records originate from non-English language literature that was not necessarily published recently. GeoRef In Process does NOT contain the most current records and should not be confused with a database of Recent References.
