Doesn't sound like much fun does it? Well, consider that the books in questions were hand written by Leonardo da Vinci or that one of the books were Alice under ground or something other like that, then it seems much more interesting. The British library has done just that, published a few selected books in a WPF showcase application that feels close to reading a real book. See for yourself!
