I stumbled upon this short (7:08 minute) video showing the process of sculpting books It features the Zen Garden Installation by Long-Bin Chen "Set in Stone". I've often wondered about the process of sculpting with books.
This video was highlighted on the website of the Halsey Institute of Contemporary Art at the College of Charleston announcing the opening of a gallery show of sculpted books. The article, published in 2013, is worth reading and pictures of the art are worth seeing HERE
NOTE: I volunteered for a year at a busy Atlanta library in the donated book section. I know what happens to all of the thousands of books that get donated and can't, or won't be, bought. This is a good thing.
