Forensic Treatment Center History:
The Library in the Dome Building
When you come in the Main Entrance of the Dome Building, (5400 Arsenal) you are greeted with towering ceilings, a classical rotunda, and glimpses of historical artifacts on the walls. The Dome Conference Center, originally a gymnasium that was added to the Dome Building in the 1920s, offers a place for trainings, seminars, and other events. Some Department of Mental Health employees still work in the building; the building has been continuously in use for 156 years.
If you travel to the basement level of the Dome Building, you’re greeted with the lowest rotunda. A sloping hall leads downwards from the Rotunda towards a unique feature of the Dome Building: The Library.
The Library in the Dome Building became the library of the Missouri Institute of Psychiatry (MIP), later called the Missouri Institute of Mental Health (MIMH). It functioned as a collaboration between the University of Missouri, MIMH, and our facility. The library provided access to the latest research for clinicians, but also supported the training and education of all the specialties on the campus, including music therapists, social workers, pastoral care, recreation therapists, medical and surgical units, psychiatric nursing, and much more.
The MIMH Library was one of the largest, if not the largest, mental health library in the United States during its time. While budget cuts forced its closure in the early 2000s, much of the library remains in the Dome Building. It is now located in the old Employee Dining Room.
The current list suggests that there are roughly 28,000 items in the library. Eventually, each of these items will be fully cataloged and added to a searchable database for use by researchers, historians, and the Department of Mental Health.
A list of the items in the Library can be accessed through the Archive’s website. If you are interested in a particular item, an appointment to view the item can be made with the archivist, Andrea Knobeloch, through email at andrea.knobeloch@dmh.mo.gov.
