The latest release from the Library of Congress' American Memory site is the Samuel F.B. Morse papers. The online collection is comprised of 50,000 digital images (available in two resolutions), 6,500 items, searchable (by keyword) and browseable (by series). The holdings span diaries, drawings, clippings, correspondence, maps, and more. The collection dates from 1793 to 1919, but most documents are from the period 1807-1872. The site offers several contextual features including a Morse family tree, a timeline, a selection of collection highlights, and a couple of short pieces: "The Invention of the Telegraph" and "The Lesser-Known Morse: Artist, Politician, Photographer."
