The WorldCat Search API and WorldCat Registry APIs have been busy! There are two free iPhone apps that use the two APIs that you might be interested in:
A barcode scanning app for iPhone called pic2shop now includes local library results thanks to Vision Smarts, a technology company based in Belgium. Pic2shop helps you compare costs at various retailers and now local libraries. A free download through Apple’s iTunes App store, pic2shop works in all countries and they’re working on translations and platforms beyond iPhone. See screen shots and a YouTube video on the WorldCat blog about it ››
Another free iPhone app is also available now called Book Bazaar. Developed by Bayview Labs in Mountain View, CA, With Book Bazaar, you type in a title, author, keyword or ISBN to compare prices for books at online or local bookstores, and now libraries. Developer Rizwan Virk says, “Book Bazaar is made for book lovers who want to find a specific book right away. The best and easiest way to find a book is at a local library, and so we want to support local libraries as much as possible.” Available for U.S. users at the moment, download Book Bazaar in the iTunes App store.
