The majority of the archives of the Concordia Club were destroyed either as a result of the ransacking of the club by the 118th Batallion in 1916, or as a result of the fire of November 17, 1971. As a result the earliest records of Concordia have largely been lost forever. A very small number of items can be traced back to the Concordia Male Choir (1873-1914). These take the form of two items of correspondence, programs for the "Sängerfests", clippings, and photographs. A small number of archival records also can be found which belonged to the "Deutscher Club, Kitchener" (1925-1930), and include a set of house rules, letters patent, and photographs. Some records from the 1930s have also been preserved to this day, and include artifacts, clippings, legal documents, a membership list, photographs, and programs of events. However, the majority of the materials date from the 1950s onwards. These materials document the history of the Concordia Club since the 1950s, and include artifacts, audiovisual material, clippings, correspondence, ephemera, financial records, legal documents, membership records, minutes of meetings, photographs, publications, and scrapbooks.

The Sims family collection encompasses records of the Sims and Cook, Davidson and Garden families retained by members of the two family branches that came together when Harvey James Sims and Florence Katherine Roos married in 1902. Their Sims and Davidson forbears were equally significant in the history of the Waterloo-Wellington area and in the growth and development of agriculture, education, business and government. Harvey James Sims and Florence Katherine Roos were deeply involved in their local community of Berlin, (later Kitchener) Ontario and their own records contain significant additions to our knowledge of local personalities and affairs. Harvey was a childhood and lifelong friend of William Lyon Mackenzie King; they wrote and visited each other regularly. King's sister Bella was also a close friend of Florence from school days on.
