Crucial to our nation’s history as author of the Declaration of Independence and third president, Thomas Jefferson was also a major figure in the Enlightenment, representing for Europeans the embodiment of the early nineteenth-century American mind. Since 1950, his writings have been compiled in the ongoing project The Papers of Thomas Jefferson. Rotunda’s digital edition brings together all thirty-three volumes published through 2006 into one searchable online resource. This content will be joined soon by the first four volumes of the Retirement Series sponsored by the Thomas Jefferson Foundation, which documents the time between Jefferson’s return to private life and his death in 1826. This XML-based edition includes all the illustrations and bibliographical content of the print edition, with the added convenience of linked cross-references and indexes.
