In 2009, Sid Lapidus, an alumnus of Princeton University, gifted over 150 books, pamphlets, and prints related to the intellectual origins of the American Revolution to the Princeton University Library. The items here also cover the early years of the republic, efforts to abolish the slave trade in Great Britain and the United States, and the Revolution itself. These materials have been digitized and are available on this site. On the left hand side of the site, visitors will find listings of these documents organized by topic, creator, genre, and language. Visitors should not miss the exquisite edition of Thomas Paine's celebrated "The age of reason: being an investigation of true and fabulous theology," printed while Paine was imprisoned in 1794. It is a remarkable collection, and the site also features a link to additional supportive materials for school curricula offered courtesy of the Gilder Lehrman Institute for American History.
