The Geologic Guidebooks of North America Database consists of references to geologic field trip guidebooks of North America (United States, Canada, Mexico). Most of the guidebooks cited are from the period 1940-the present. A few are from earlier years. Geoscience Information Society (GSIS) volunteers compiled the lists of guidebooks using The Union List of Geological Field Trip Guidebooks of North America as a starting point. References from the GeoRef database have been used to provide the searchable data for the earlier publications and newer guidebooks have been identified in GeoRef and are being regularly added. GSIS volunteers keep GeoRef informed about new guidebooks. This guidebook database builds on a long history of collaboration between GSIS and AGI that resulted in the publication of several print publication including The Union List of Geologic Field Trip Guidebooks of North America, sixth edition, compiled and edited by the Geoscience Information Society Guidebooks Committee, Richard Spohn, Chair, published by the American Geological Institute in 1996.

The database is updated monthly and contains more than 10,000 references.
