They save shelf space in cramped prison libraries, librarians no longer have to file updates in the books, and they make it easier for prisoners to find informtion. Prison oficials wanted to be sure that the kiosks were tamper-proof. The touch-screen monitors are covered in shatterproof glass inside a steel box bolted to a wall. "We've taken a crowbar to it. It doesn't shatter," said a company official.
