The journals of Lewis and Clark housed at the American Philosophical Society constitute the major source of information on the transcontinental scientific expedition of the Corps of Discovery in 1804-1806. The bulk of the collection is comprised of 18 "codices" bound variously in red morocco leather, brown leather, or marbled-paper boards, and 12 loose leaf codices, these were kept alternately by Captains Meriwether Lewis and William Clark during their journey with the Corps of Discovery. Entries on the voyage west were made almost daily with few exceptions, though on the return voyage, there are several, occasionally substantial gaps.
