The Virtual Librarian
"Information technologist Keith Robertson keeps reminding himself that Lib is not a real person; she's a virtual librarian--software, nothing more. But her software is evolutionary, designed to keep improving itself as it learns. So she is outgrowing her creators and developing a mind of her own. Keith's whole future, including his job and his marriage, depends on Lib. And Lib is out of control"--Publisher/distributor website.
