With the emergence of large scale multi-touch screens we may be able to create a life-size digital bookshelf. See the following pointers:
Imagine a 4ft x 6ft screen which renders a bookshelf, but a bookshelf augmented with faceted search, re-organization, etc. essentially allowing the books on the shelf to re-organize themselves and the ability to "grab" the books for later viewing on-line or desk pick-up. Another benefit is that the shelf could be made to work with a very large catalog of publications and not be limited by its physical size.
