Barnes & Noble has introduced a Nook kids for iPad application. The app makes B&N’s digital catalog of children’s content—which includes 100 new interactive kids’ books–available on the e-reading device. To promote the new app, B&N is offering two free picture books: Richard Scarry’s Colors and Rudyard Kipling’s The Elephant’s Child, which will automatically appear in a customer’s digital library when they register.

The retailer says the app was designed specifically for children, with features such as AliveTouch technology that lets kids easily find a favorite story, digitally turn pages, interact with the text, and zoom in and around graphics. The app has a password-protected Parent’s Corner that helps parents select which books are appropriate for their children.

More than 12,000 children’s chapter books will also soon be available on Nook kids for iPad. The app is available free at www.NOOKkids.com/ipad and www.itunes.com/appstore.
