This summer, I hope to help our library add a chat reference button to our OPAC (Aleph500 from ExLibris). The libraries at the University of Iowa have already done this with their implementation of Aleph 500.
I’d also like to find out what database vendors will let our library add a chat button on database search screens. I’ve heard that Gale allows this, but I haven’t had a chance to see what it looks like. I can imagine that EBSCO might allow this, too, as they already give us space to put a link to the library’s web site at the top of the screens for the main different databases we get from them (Academic Search Premier, Business Source Premier, EconLit, MasterFile Premier, PsycINFO, etc.)
The logic for adding a chat button to database and OPAC pages is obvious: offer your help as a librarian where the users actually are. Users shouldn’t have to backtrack to the library’s web page to launch a chat. Now if only we could figure out a way to get some real estate on Yahoo! and Google.
