This collection contains materials related to the Province's relationship with the Conference of Major Superiors of Men (CMSM). Founded in 1956 to encourage cooperation between different men's religious orders, the CMSM is the national organization representing leaders of Catholic religious institutes for men, monasteries, and societies of apostolic life in the United States. The Province has been an engaged member since its inception.

The collection is composed of two series, each comprising one box each. The first series contains correspondence and meeting notes from 1956 to 2003. There is a sub-series for correspondence relating to then Provincial Gerard Cleator's time as head of the Religious Life Committee.

The second series covers materials relating to the John Jay Report and the policies enacted by the CMSM. This series is restricted and requires prior approval to access.
