CanGeoRef is a subset of GeoRef (www.agiweb.org/georef), the earth science literature database built and maintained by the American Geological Institute (AGI) which contains 3.2 million references. CanGeoRef will eventually include all Canadian Geoscience Literature published since the early 1800s.
Currently, CanGeoRef contains more than 200,000 references to Government (Federal and Provincial/Territorial) publications, peer reviewed journal articles, (chapters in) books, theses, and maps. A subscription to CanGeoRef may be as low as $95.00 per year for an individual subscriber and is maximally $800.00 per year for a medium-sized company.
