We’re pleased to share that the Mary Ann Shadd Cary fonds (F 1409) has been inscribed on the Canadian Commission for UNESCO’s Canada Memory of the World Register. This inscription was the result of a collaboration with Library and Archives Canada. It demonstrates the importance of Shadd Cary to the collective history of Canada.
