New Providence, NJ – January 20, 2012 - Bowker is developing Stacks, a mobile app for iPhone™ that will allow subscribers to Books In Print® and RCLweb™ to scan a barcode or enter an ISBN, link to basic metadata in Books In Print and add items to their existing lists in Books In Print or RCLweb. Using the Stacks app, book buyers in a store, faculty office or at a trade show will be able to simply scan and save titles from Books In Print on the spot to their device. And collection weeding in libraries will happen right from the stacks, eliminating the need to cart books back to a desk for evaluation.
