Geologic Field Trip Guidebooks Web Archive collection derivatives

Web archive derivatives of the collection Geologic Field Trip Guidebooks Web Archive from the Ivy Plus Libraries Confederation. The derivatives were created with the Archives Unleashed Toolkit and Archives Unleashed Cloud.

These derivatives are generally small enough to work with on your local machine, and can be easily converted to Pandas DataFrames. See this notebook for examples. Domains
