Montana Historical Society

Big Sky. Big Land. Big History.


The Research Center is a non-circulating library, archive, and photo archive with collections available for onsite use as well as digitized materials available online.

We are pleased to offer limited in-person research.

Construction on the New Montana Heritage Center has begun! Parking can be more challenging. You may need extra time, and patience, when parking for your visit to the Research Center. Since the area around the Montana Historical Society is an active construction site, please be aware that there also may be construction noise during your visit or unexpected closures.
