The twenty-three document boxes which comprise the collection are divided into three sections, reflecting the changes which the Conference underwent between 1909 and 1963. Section One (boxes 1 through 4) cover the Rocky Mountain Faculty Athletic Conference, 1909-1937. Section Two (boxes 5 through 16) cover the Mountain States Intercollegiate Athletic Conference, 1937-1950. Section Three (boxes 17 through 23) cover the expanded MSIAC, 1951-1962, the so-called "Skyline Conference."

The papers give an uneven coverage to the various schools (and even to the various sports) of the Conferences. The reason is apparently to be found in the rotation secretaryship. For example, the early years center almost exclusively on the Colorado Schools; the late 1930s on the University of Wyoming. Only after the appointment of a full-time Commissioner for what came to be known as the "Skyline" Conference is there anything like a uniformity of coverage in all phases of Conference activity. The formation of the Presidents' Council (Presidents of member institutions) and the regularity of its meetings and the minutes therefrom provide an effective overview of the Conference.
