This database contains references to geologic field trip guidebooks of the United States, Canada, and Mexico. Most were published 1940 to present. The database is updated monthly and contains more than 10,000 references, but no full text. (AGI)
This project aims to preserve web-based geoscience field trip guidebooks — which document local geologic information and are often ephemeral, and only available for a short time — found in the Geologic Guidebooks of North America Database.
