On Demand Books LLC (ODB) uses proprietary software and a patented, fully integrated high speed machine to print, bind and trim  a library quality paperback book at point of sale on demand in minutes at low cost from digital  files. The Espresso Book Machine replaces the centralized supply chain for the distribution of books – essentially unchanged since Gutenberg – with radically decentralized direct-to-consumer distribution. In essence, an ATM for books.

ODB was founded in 2003 by Jason Epstein, Chairman, and Dane Neller, Chief Executive Officer, and is based in New York City.
