HP Makes Rare and Hard-to-find Books Available Through Collaboration with University of Michigan
HP BookPrep delivers access to nearly 500,000 out-of-print library books
HP BookPrep – a cloud computing service that enables on-demand printing of books – brings new life to the traditional publishing model, making it possible to bring any book ever published back into print through an economical and sustainable service model.
As part of a growing movement to preserve and digitize historic content, major libraries are partnering with technology leaders to scan previously hard-to-find works using high-resolution photography. HP’s process transforms these scans prior to printing by cleaning up some of the wear and tear that often is present in the originals.
People can now purchase high-quality print versions of public-domain, out-of-print books from the University of Michigan Library through HP BookPrep channels, including traditional and online retailers such as Amazon.com.
