Mixed-media book publisher Vook announced yesterday that it is releasing 19 titles on the iPad. The vooks, with their blending of content and video, are ideal for the device, which allows for the incorporation of more media options in the reading experience than existing, dedicated e-readers. A representative at Vook said this type of content was "tailor-made" for the iPad. The vooks' prices vary, ranging from 99 cents to $9.99, but the rep said the average title is between $4.99 and $6.99.

Vook is also currently giving away two titles--Love, Love, Love: Shakespeare in the City and The Sherlock Holmes Experience--which, like other vooks, can be found in Apple's iBookstore. Other vooks include titles by Anne Rice, Seth Godin and Gary Vaynerchuck.

Speaking to the significance of the iPad's launch to the vook format, Vook CEO and founder Brad Inman said: "We will remember the iPad launch as the day that the publishing industry officially made the leap to mixed-media digital formats and never looked back."
