The National Library of Medicine has a number of very nice online exhibits, and they recently created this all-encompassing image collection to give users access to almost 70,000 images taken from their History of Medicine Division. The collection includes portraits, photographs, genre scenes, posters, and graphic art works that detail and illuminate the social and historical aspects of medicine from the 15th to the early 21st century. Given the size of the collection, new users may wish to start things off by clicking on the "Help with Searching" section. Visitors can use the site to order images, learn about potential copyright issues involved with some of the images, and perhaps even look through their FAQ area.
