The accrual consists of records related to various members of the Breithaupt family including business activities, correspondence and biographical information.

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.

One scrapbook maintained by Eunice Gearard with clippings about people affiliated with the Kitchener Collegiate Institute (KCI) as well as about people from Kitchener-Waterloo who participated in the Second World War.

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.
