Affiliated with the University of Toronto, the Thomas Fisher Rare Book Library houses more rare books than any other collection in Canada. The collection includes unique artifacts like Newton’s Principia (1687), Shakespeare’s First Folio, the Nuremberg Chronicle (1493), and a Babylonian cuneiform tablet dating to 1789 BC. Robert S. Kenny, a Communist Party of Canada member, also donated a large part of the collection. In all, the rare book library includes more than 25,000 items with a special focus in labor movements worldwide, though with a particular emphasis on Canada and its history.
