The best short Jefferson bio. is Bernstein’s THOMAS JEFFERSON. The best book on Jefferson’s political philosophy is David Mayer’s THE CONSTITUTIONAL THOUGHT OF THOMAS JEFFERSON; Mayer happens to be a libertarian law professor. I’m presently writing a book, THOMAS JEFFERSON, REVOLUTIONARY, that will cover … what the title indicates. There are a plethora of Jefferson books — basically one on any sub-topic that comes to mind, such as Jefferson as gardener, Jefferson as diplomat, Jefferson as constitutionalist, Jefferson and Madison, Jefferson and Marshall, Jefferson and Adams, Jefferson in retirement, Jefferson and UVA, Jefferson and France, Jefferson as architect, Jefferson and women, Jefferson and Indians, Jefferson and slavery, Jefferson and Hemings, Jefferson and the Declaration, etc. If she comes up with some sub-topic that she’d like to explore, I’ll be happy to recommend a title.
