Wednesday, Nov 12 at 6:30AM (Eastern), CONSULS will be down for about half an hour for some maintenance work. The catalog, staff functions, and login to the databases will be down. I'm pretty sure if you are already in a database you will be fine, since the needed cookies will be set, but you won't be able to log into the databases during the outage. I'm not sure about switching from one database to another--I suspect that changing within a vendor would be fine, but maybe not between vendors. (I.e. you could switch from Academic Search Premier to ERIC, both on EBSCO, but maybe not to Library Literature, on FirstSearch.)
Sorry for the inconvenience.
