Sierra, the software that the Libraries use to manage our physical collections, is being upgraded the morning of January 4. Because of this upgrade, the Classic Catalog and My Library Account will be unavailable beginning at 9:00am. 3Search will be available, but will not display call numbers or availability information for items in Grinnell’s Collections. All services are expected to be restored by 11:00am. Access to online databases, interlibrary loan, and other services will not be affected.
