Housed in the 1828 Blackman-Bosworth Store building in the center of Beverly, the museum has a broad-based collection including early settlement tools, Civil War artifacts, belongings of early citizens, store and business collections, and much more. Behind the museum, open by appointment or during special events, is an original subscription school rescued from a rural Randolph County location. This small schoolhouse originally housed a school "subscribed" by parents who would band together to hire a teacher before universal public education in the area. Today it features an extensive collection of one-room school artifacts and memorabilia. Under construction behind the museum is the relocated Stalnaker Cabin, an early settlement log cabin. Saved and moved by the Stalnaker Family Association, the cabin is being restored by the Society and will be a future addition to the museum holdings. The museum also features rotating special exhibits in the meeting room, as well as hosting the regular informative programs of the Society.
