includes the almost incredible volume of Jefferson's writings on practically every aspect of human life-from politics and diplomacy to architecture, philosophy, agriculture, and music. The series includes 18, 000 letters written by Jefferson and, in full or summary, 25, 000 letters written to him by the great and humble of many nations. No previous edition has included more than fifteen per cent of the total, and only about a fifth of the documents have ever been published anywhere. Covering the years 1760-1776.
