On Demand Books announced today that it had signed a deal with Google to tie the more than 7 million titles available via the Espresso Book Machine into Google Books. Customers will soon be able to find books on the Google Books website and (where avaialble) buy the book and have it printed at the nearest Espresso Book Machine.

“We are pleased to announce this latest milestone for our network,” said Dane Neller , CEO of On Demand Books. “Our existing relationship with Google enables over 2 million public-domain titles to be purchased on Google Books. By registering our entire catalogue of over 7 million titles with Google Merchant Center, all of our content, including in-copyright and publisher titles, will soon be available for discovery and purchase on Google Books and through other Google e-commerce services.”

On Demand Books has been steadily adding publishers since the first EBM shipped a few years ago. Current publishers include Random House, HarperCollins, McGraw-Hill, Hachette, Simon & Schuster, WW Norton, Macmillan, and many others.
