Archives and Special Collections are open by appointment only, limited to UMN affiliates. Appointments must be made one week in advance of your visit. Contact ascref@umn.edu for assistance or the curator of the collecting area you wish to use. We continue to provide scans of requested research materials when possible, especially for our non-campus clientele.
