Starting Friday, July 9th at 6:00a.m. SDLN will be doing a major upgrade of the software that the Watertown Regional Library uses for circulation and everything else. The upgrade is projected to be completed by Monday morning, July 12th. During the upgrade the catalog will be availiable, but real time data relating to items checked out will not be correct and online renewal of items will not be functional. The library staff will only be able to check items out to individuals. They will not be able to tell you what you have checked out, what is overdue, when items are due or to renew items. Please be patient and ask us for help; we will do what we can.
