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.

Based on an abundance of caution, the Montana Historical Society is taking steps to protect the health and safety of our staff and the public during the COVID-19 outbreak. MHS has closed its museum galleries, Research Center, Museum Store, and the Original Governor’s Mansion to the public until further notice. There are many other options for conducting research using Research Center collections. Use this document as a guide to other means to access our collections or check out our online resources.
