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.

Fonds consists of one scrapbook assembled by Ethel and Anne Longfellow during their attendance at Smith College, Massachusetts between 1902-1906. The scrapbook contains correspondence, photographs, programmes, clippings, notes and ephemera detailing the academic and social life of the sisters.

Four large albums, entitled "Pan Politae and Friends", that contain photographs, ephemera and text, both original and copies, relative to the history of the Pan Politae Club, as well as photographs and biographical information about its members from 1938 to 1995.

The history of Pan Politae is documented through current and historical portraits, as well as photographs of activities such as reunions. The albums include photographs of fundraising projects like the Christmas tree sales and service projects events held with the Young Men's Christian Association (YMCA) camps. Photographs depict service work done primarily in Camp Wabanaki at its original location on Beausoleil Island, Georgian Bay, which was destroyed by fire in ca. 1970.

These albums were compiled to commemorate the 100th anniversary of the Kitchener-Waterloo YMCA. Included are portraits of and information about K-W YMCA Presidents, influential members, former staff, and information about awards and recipients. Also included is correspondence addressed to Lloyd Stamp from former members of the Pan Politae Club where they discuss their experiences and reflections from their time in the club.

One scrapbook kept by Maria Louise Clough while on a trip from Boston to England, Scotland, France and Italy in 1886 and 1887. The scrapbook contains cards, correspondence, clippings, ephemera, and realia (including plant material), and provides insight into the activities and tastes of a young woman from that period of time. Among the contents are: Cunard ephemera (including deck plans, menus, passenger list), theatre ephemera (including Henry Irving in Faust at the Lyceum), a cigarette, lace, Westminster Abbey ephemera, transportation tickets, a moving-part Christmas card, fringe forming part of the decoration of the funeral car of the Duke of Wellington, postcards, engravings, hotel ephemera, identified leaves and flowers, etc.

One photograph album with 67 black and white photographs showing various callisthenic movements using a "wand." Each photograph includes a caption with the movement and position of the wand indicated. 5 photographs are missing from the album. The album is titled "Senior Wand Work" and dated 1906 by M. [Lucile] Adams.
