The catalog in your hand

At the Top Technology Trends I seconded that we need to get library services on handhelds, and I said that I'd like to be able to walk through the stacks and have the same access to the library's online services as I do when I'm at home. If your handheld device is especially nifty, you probably can browse the library web site and catalog, but for those with really small screens, it might be best to have a "mobile view." Here's an interesting example from BibliotecaLudwig Von Mises in Guatemala.
