The maker of the Espresso Book Machine, On Demand Books, more than doubled the number of books that it supplies to bookstores and libraries that use its POD system with today’s announcement that it signed an agreement to provide access to more than two million public-domain titles in the Google digital files. This is in addition to the 1.8 million titles already available to the Espresso from other sources, including Lightning Source.

“With the Google inventory,” said On Demand Books cofounder and chairman Jason Epstein, “the Espresso will make it possible for readers everywhere to have access to millions of digital titles in multiple languages, including rare and out-of-print public domain titles.” While it grows its content, On Demand Books has added more outlets. Among the bookstores that will install Espresso Book Machines later this fall and winter are: Harvard Book Store in Cambridge, Mass.; Boxcar and Caboose Bookshop & Café in Saint Johnsbury, Vt.; Third Place Books in Lake Forest Park, Wash.; Village Books in Bellingham, Wash.; and Schuler Books & Music in Grand Rapids, Mich.
