A large number of Bell's writings, personal correspondence, notebooks, papers and other documents reside at both the United States Library of Congress Manuscript Division (as the Alexander Graham Bell Family Papers), and at the Alexander Graham Bell Institute, Cape Breton University, Nova Scotia; major portions of which are available for online viewing.
