Inside HP Labs: 8 cool projects

On tap: A color thesaurus, photonics, and book and magazine publishing

BookPrep: A stark departure from data center research and photonics innovations, BookPrep is an interesting project that allows anyone to submit an out-of-print book and turn it into a printed book. Andrew Bolwell, an HP Labs director, says there are currently at least 90 million books out of print today.

Books are scanned in a non-destructive way, removing any artifacts and yellowing, and then are printed and bound in a professional way. Google is involved from a scanning perspective and books are printed in any quantity -- from one to hundreds. The entire process is automated and takes just 24 hours for a book instead of the usual three to six months.
