This first link will take you to the art of Brian Dettmer, aka The Book Surgeon. Currently a resident of Atlanta, Dettmer has been working with books as art projects for almost 10 years. He begins with old and out-of-date encyclopedias, medical journals, dictionaries, and other similar books, manipulating the pages and spines in various ways to form the shape of his sculptures, sometimes combining multiple books in one piece. He then uses a variety of small precision tools to remove material, until you end up with interesting art like the piece shown to the right.
