The establishment of Bloomington's Mennonite Hospital dates to 1919. By 1940, the hospital operated a nursing home and a nursing college. In 1981, Mennonite merged with Brokaw Hospital in Normal to become BroMenn Medical Center. It was later part of the Illinois and Wisconsin-based Advocate Aurora Health Care system. In 2020, BroMenn was acquired by Carle Health hospital.

The collection includes various newsletters (1960 to 1995) for hospital employees, patients, volunteers, supporters, and the community at large. There is also a collection of hospital press releases, 1980-1982.
