Fahrenheit 451 is a novel by Ray Bradbury, about a totalitarian society where books are burned, by a government that wants to suppress ideas.
German-Jewish poet Heinrich Heine once said: "Wherever books are burned, human beings are destined to be burned too."
Canada's collective written and photographic history is being gutted---Library and Archives Canada; and the Agriculture Canada, Environment Canada, Transport Canada, Citizenship and Immigration, Industry Canada, National Defence, Public Works and Government Services, National Capital Commission and Public Service Commission of Canada libraries have been told to decentralize, photograph, and get rid of their collections.
The National Capital Commission is the custodian of Canada's official residences, including 24 Sussex Drive, Rideau Hall and 7 Rideau Gate. I know for a fact that Library and Archives Canada has hundreds of historic photographs of NCC buildings in Ottawa.
Pierre Berton used LAC material for his books about the history of the Canadian Pacific Railway, and the Dionne quintuplets.
