The sous-fonds contains correspondence, contract negotiations and agreements, text of speeches and notes by McClure, U.S.W.A. publications, materials relating to the 1946 strike, and photographs.
The fonds arrived in complete disarray. His domestic correspondence, bills, bank accounts with many overdraft notices, and numerous requests for payment from local merchants were mixed together with his union papers which, in themselves, had no order either. With the exception of correspondence he received from his friends serving with the Canadian forces during World War II, none of this domestic material has been retained. What remains has been arranged as follows: correspondence; appointment calendars and diaries; labour negotiations; committees; Steelworkers Social Club; finances; conferences; photographs, job descriptions, personal documents, articles and notes, printed materials and realia.
