Barnes & Noble’s Nook Media has updated its Nook for iOS app, bringing comic books to iPad and iPhone users. The update adds access to buy more than 8,000 comics and graphic novels from Nook. The app now features Nook’s Zoom View tool which lets readers automatically focus on individual panels in graphic novels and comics.

To promote Nook Comics on the Nook iOS app, Nook Media is giving away a free DC Comics 2013 Superman Sampler, which includes excerpts from Superman: Last Son of Krypton, Superman: ForTomorrow, Superman: Earth One, and Justice League Volume 1: Origin.

“With our free, updated Nook for iOS application, we’re delivering to customers with iPad, iPhone and iPod Touch a great optimized reading experience, now with access to NOOK Comics, one of the leading collections of digital comics and graphic novels available,” stated Jamie Iannone, president of digital products at NOOK Media.

Nook has been in the news recently as speculation of a Microsoft buyout has been reported and then called a rumor.
