The museum and archives are currently closed to visitors and researchers due to the COVID-19 crisis. We expect to reopen in spring 2021. Research requests and services may be met by staff on a limited basis and in the order received.
When the museum is open, the archives and material in the Reference Library are accessible to researchers who are at high school level and above, by appointment only. Materials in the library are non-circulating; however, photocopies and/or digital images of some materials may be requested subject to the policies of the Society and at the discretion of the archivist.
