Using LibraryThing, the biggest book cataloguing site in the world, consumers can get mobile access to their book collection. LibraryThing has interfaces with Amazon, the Library of Congress and over 690 other libraries around the world. Members have catalogued over 30 million books since the site opened and can look at their collection (and others') either as a list or as a gallery.
Future vision by Erwin van Lun
Currently we have to catalogue books manually, but soon LibraryThing will have an application that lets us take a picture of the books on our shelves and recognize them immediately. All newly bought books will be added immediately and when we look at a book we’ll hear (for example) that we already have it, but haven’t read it yet. Slowly the dialogue is being formed and the product is its topic.
