CNN writes about a $50,000 machine that can print books on demand. It can print up to 550 pages and put a binding on the book in seven minutes. It will be debuting in a select number of U.S. libraries in 2007.
The machine is the 'output' end of a service called On Demand Books, which is also just debuting. Initially, some 2.5 million books are now available - about one million in English and no longer under copyright protection. On Demand accesses the volumes through Google and the Open Content Alliance, among other sources.
