HP released the latest of their cloud offerings today. What was a result of HP printing trying to figure out how to print more in an era of less paper. HP Labs initially looked at a small project that digitized some old books. The thought was that while a publisher will not print a single copy of a book with current digital presses and a collection of books, a printer can not print the single copy. The move into the cloud was simply a way to support the project on a large scale. Bookprep.com lets you search, find, preview rare, out-of-print and hard to find books on every topic imaginable.
