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.

A gold two-button blazer from the University of Waterloo worn by Peter Dallas (BSc '72), an undergraduate student in one of the first kinesiology classes at the University of Waterloo. The front left side of the jacket includes a patch with the University of Waterloo name and the School of Physical Education and Recreation logo on the chest pocket. The jacket was manufactured by Sainthill-Levine Co. Ltd.

According to Peter Dallas, the blazer was ordered for students in the first kinesiology classes by Dr. Robert (Bob) Norman and Neil Widmeyer, both faculty members in the School of Physical Education and Recreation during that period.

Peter Dallas wore the blazer with pride at numerous alumni reunions and had recently celebrated his fiftieth-year anniversary in 2022.
