Penguin has a new book app available for Ayn Rand‘s controversial text Atlas Shrugged. The interactive app includes audio and video of the author, as well as scans of her notes on the subject.

The app also includes social media sharing features. Here is more from the app’s iTunes listing: “While immersed in the app, readers also have the option to share favorite passages and quotes from the novel on Facebook, Twitter, and via email with a few quick taps—and without ever leaving the page.”

This is the third time this year that the publisher has taken a popular old book and repurposed it with special features to turn it into an app. eBookNewser has more: “Penguin has been making their mark this year by creating interactive eBook apps for classic books. They are the publisher behind Jack Kerouac‘s On the Road app and Wreck This App, the digital version of Keri Smith’s bestselling Wreck This Journal. The Ann Rand app is $14.99 (less than the $16.99 Kerouac app, more than the $7.99 Smith app).”
