I've seen the book fountain all over the bookternet. It rests at the Public Library of Cincinnati and Hamilton County in downtown Cincinnati, Ohio.
I wanted to baptize myself in the book fountain, but they had the water turned off since it's freezing outside. I still thought it was pretty magnificent, though.
And I got some sweet deals on audiobooks from the library's book sale room. As the busiest central library in North America, you can bet they had a good selection.
