The McGill Library is pleased to launch the Osler Library Prints Collection, a searchable and browsable website of 2,500 visual documents related to the history of medicine, spanning several centuries, countries, and artistic media. Ranging from the seventeenth to the twentieth century, the collection consists predominantly of prints, though it also includes some photographs, drawings, posters, and cartoons. Medical professionals throughout history are represented largely through portraiture, as well as through caricatures and scenes. The images in this collection, acquired from various donors at different times, are fascinating for both their historical significance and their artistic merit. Straddling the disciplines of art and science, the collection is a valuable resource on the history of medicine and the history of portraiture.
