Until further notice, the University of Minnesota Libraries Archives and Special Collections are open by appointment only and appointments are limited to UMN affiliates. Appointments must be made one week in advance of your visit to enable us to page and quarantine collection materials before use.

Please contact ascref@umn.edu for assistance or, if known, the curator of the collecting area you wish to use. We will continue to provide scans of requested research materials whenever possible, especially for our non-campus clientele.
