We use a product called Meebo to provide an interface for chat service on our website, where we can answer your questions in real time. Google recently acquired Meebo, and then promptly decided to end the service effective July 11. That is why our users see the notice "MeeboMe is being discontinued" on our Ask a Librarian page.
It is the providers of the little box that are ending service, not the libraries. Please rest assured that we will have a replacement for Meebo in place before July 11, a (slightly different) little chat box will be where it has always been, and online chat will continue as always. And if, for some reason, chat gets a little flaky in the interim, you can always send your questions by email. We have a staff of librarians still happy to help.
