Working with the U.S. National Library of Medicine (NLM) History of Medicine Division, the Lister Hill Center launched Profiles in Science in September 1998. The site uses innovative digital technology to make available manuscript collections of prominent biomedical scientists, medical practitioners, and those fostering science and health. Most collections have been donated to the NLM and contain published and unpublished materials, including books, journal volumes, pamphlets, diaries, letters, manuscripts, photographs, audio tapes, and other audiovisual resources.
