Series consists of materials transferred in the Archives holdings in the 1970s and left in piles on shelving units. No original order was apparent. After viewing materials it was discerned that the best course of action was to sort material by Ryerson President and then organize chronologically by their time in office.
The series has been divided into sub-series by President from 1948 to 1980. Presidents were: Howard Hillen Kerr, Fred Jorgenson, Anthony Wilkinson, Donald L. Mordell, George Korey and Walter G. Pitman.
