The mention of James Madison conjures up images of the emergence of the U.S. Constitution, as well it should. In this remarkable new digital collection, the American Memory Project at the Library of Congress presents over 12,000 items in some 72,000 digital images that offer a detailed and authoritative portrait of the man who is often referred to as the "Father of the Constitution". This portrait effectively emerges from the diverse set of documents offered here, which include personal notes, drafts of letters and legislation, and autobiography, and correspondence. The collection itself is organized into six series, and it begins with a selection of his father's letters and continues all the way to the postwar years of his presidency. The digital collection is further enhanced by four nice essays, including an introductory piece by John C.A. Stagg and a rather intriguing piece on the ciphers used by Madison in his correspondence. The site is rounded out by a search engine and a timeline.
