The Libraries IT Division is planning to upgrade Sierra to Release 4.2 (from 4.1) on Monday, March 11 beginning at 10 am. This will require approximately five hours of downtime for both Sierra and the library catalog. We chose that date because it occurs when the number of people affected by the downtime will be diminished.

While we upgrade the system we don’t expect the system to be down for more than five hours, but we will send out an update should that time be extended for any reason. We are expecting this upgrade will resolve several issues that are outstanding.

If have any problems following the upgrade, please report them to Hub (
