Museum
In October 1970, the State Library Commission moved out of the Liberty Memorial Building (LMB) and into what was known as the Randal Building on the north side of Bismarck (4023 State Street).
Throughout the 1970s and into the 1980s, the LMB primarily housed the State Historical Society and the State Museum. The basement and first floor held offices, laboratories, storage, and a reading room. The first floor also included a room for the Secretary of State's Central Microfilming Service. The second and third floors housed the exhibits.
The "Stack Monster"
It was during this time (roughly the late 1960s into the 1970s), that some State Historical Society employees began experiencing oddities in the LMB. Staff, often while working late at night, reported footsteps, coughing, shadows, or voices; but no one would be there. The paranormal presence was nicknamed the "Stack Monster."
Heritage Center
In 1981, the State Historical Society and the State Museum left the LMB and moved next door into the newly completed Heritage Center, its present location.
