HarperCollins Children’s Books says more than 30 of its most beloved picture books are available as e-books in time for the holidays. For the first time, Fancy Nancy, Splat the Cat, and that feisty dog Marley can be viewed digitally on the iPad, iPod touch, and iPhone through the Apple iBookstore and on NOOKcolor by Barnes & Noble.

Also, Disney Publishing Worldwide has debuted illustrated books from Tron, Toy Story, Cars and other favorites on the iBookstore. The books — priced from $2.99 to $9.99 each — offer full-color, two-page spreads.

The iBookstore features books from major and independent publishers. Once you’ve bought a book — or download a free one — it’s displayed on your Bookshelf. Just tap it to start reading. The iBooks is a free download at the Apple App Store.
