The agreement means that users can choose from more than 3.5m different titles that can be printed, bound and trimmed in a few minutes.

The titles are made available through EspressNet software, which securely connects the machines to the library where the files are held and tracks jobs and payments to authors.

The new titles from Google are out-of-print or out-of-copyright books, although the machine is also popular with self-publishing authors.

Jason Epstein, chairman and co-founder of On Demand Books, said: "With the Google inventory, the EBM 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."

The EBM has been installed in a number of sites around the world, including the Blackwell bookshop in London, as well as the University of Michigan Shapiro Library Building in Ann Arbo, US, the Bibliotheca Alexandria in Alexandria, Egypt, the University of Alberta Bookstore in Edmonton, Canada, and Angus & Robertson Bookstore in Melbourne, Australia.

Blackwell's head of marketing, Phil Jameson, said that the trial was going well, although wouldn't discuss the volumes of material being printed.

"The ultimate goal is to roll this out to our other stores," he said. The company also has a significant library supply arm and Jameson said that Blackwell was investigating offering libraries the EBM machine.
