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.
RESEARCH CENTER IS CLOSED FOR CONSTRUCTION AND RENOVATION.
We estimate we will reopen in late 2025.
During the closure, Library & Archives collections are in storage for safekeeping and not accessible. However, online resources will be available, including historic newspapers, as well as all collections found on the Montana History Portal. Limited remote research services will also be available. We apologize for the inconvenience. Please direct questions to mhslibrary@mt.gov.
