Starting in January 2026, the Hoffman Research Library (1385 Mendota Heights Road, Mendota Heights, MN) will be open on the second Sunday of each month from 12:00 noon until 4:00 pm.

However the library will be closed if 1) volunteers are not available to assist researchers, or 2) the Twin Cities metro area is under a Winter Storm Warning. Check here to see hours, as well as scheduled and unscheduled closings.

The Hoffman Research Library will be closed for patron use during Christmas week, December 21-27.
