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 Nov. 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.

Accrual consists of materials created and accumulated by Alice Riggs Hunt and her family. Includes correspondence to and from Alice, locks of hair, and photographs. The photographs document other members of the Hunt family including her mother Mary Osgood Riggs Hunt (1860-1953) and her brother Charles Warren Hunt Jr. (1888-1953). Also present are over 500 slides documenting Charles Warren Hunt Jr.'s trip around the world.
