This guide leads to free Internet sites containing relevant, reliable, and rich content including published and unpublished sources, maps, manuscripts, and illustrations. “Geoscience” was not a term known to Jefferson within his time, so the clues to information provided here deal with Jefferson’s interest in and knowledge of geography, geology, nature and environment.  In these search result sets there will be some redundancy and there will be some irrelevant items – so browsing and critical selectivity is required.
