Book-Sniffing Breaks

From a comment by 'Frank' at the Statistical Modeling, Causal Inference, and Social Science blog:

As for libraries, ever heard of E-books? I foresee the rows of books being used for amusing random walks over information space.
I say put all the books on-line for research, and display only a random sample of the physical collection for book-sniffing breaks. The latter should change monthly and be accompanied by a free hot latte.
