The Archibald papers in the Canadian Architecture Collection constitute only a very small portion of the architects' professional and/or personal records, since the office records and the private correspondence of John S. Archibald and his associates are not represented in their entirety. The papers, given to the archive by Hugh Percival (Peter) Illsley, consist primarily of photographic reproductions and postcards of buildings in Europe. Also included with this original material is related information gathered over the years by John Bland dealing with different aspects of John S. Archibald and Charles J. Saxe's professional activities.
