"Essentially, Jeff installed a printing press to close the inventory gap with Amazon.  The Espresso Book Machine sits in the middle of Harvard Book Store like a hi-tech visitor to an earlier era. A compact digital press, it can print nearly five million titles including Google Books that are in the public domain, as well as out of print titles. We’re talking beautiful, perfect bound paperbacks indistinguishable from books produced by major publishing houses. The Espresso Book Machine can be also used for custom publishing, a growing source of revenue, and customers can order books in the store and on-line. You can walk into the store, request an out-of-print, or hard-to-find title, and a bookseller can print that book for you in approximately four minutes." - JoeCamel
