The Shifted Librarian and the Free-Range Librarian have both mentioned a new product called "Summon" that promises to revolutionize searching within the library. It provides a Google-like interface to all a library's online data. Results of a search may be drawn from catalog records, announcements of upcoming events, or online texts. Libraries already use meta-search engines that can look for results in various databases. This, if I understand it correctly, promises to be more seamless and rapid.
