The Soo Hardware Company was a full-service hardware wholesale and retail store located in Sault Ste. Marie, Michigan. It carried a complete line of building materials, plumbing and electrical supplies, stoves and furnaces, major and minor domestic appliances, housewares, sporting goods, and bicycle and auto parts. The records consist of inbound correspondence received between the years 1911 and 1918. The bulk of the correspondence consists of sales letters and invoices from manufacturers and wholesalers, covering the wide range of semi-finished and manufactured goods sold by the Soo Hardware Company. A large number appear to be unsolicited mailings from salesmen, while others document a long working relationship.
