Vook has secured $5.25 million in Series A financing from several investor sources including VantagePoint Venture Partners and Floodgate.

Marketwire has a quote from Vook CEO Brad Inman: “We are excited to bring new and existing investors into this round … They recognize that Vook is leading the way with a new vision for book publishing, creating value for authors, filmmakers and book publishers.”

Late year, Inman explained how to turn books into vooks at the eBook Summit–exploring the the Vook, JFK 50 Days.

In an eBook Summit talk, Vook CEO Brad Inman and Perseus Books Group online marketing director Peter Costanzo explained the process for turning a print book into a multimedia product.

Vook partnered with NBC News to acquire several film reels chronicling the days of John F. Kennedy‘s presidency and approached Perseus to collaborate on a project that eventually spawned the vook, JFK 50 Days. The video embedded above showcases the iPad app version.

They then acquired the multimedia rights to the title, JFK: Day by Day: A Chronicle of the 1,036 Days of John F. Kennedy’s Presidency by Terry Golway and Les Krantz. Multimedia rights cover the inclusion of multimedia content embedded in the text. Perseus picked 50 moments from the footage in celebration of the 50 years that have passed since Kennedy’s presidential election.

To find out more, we caught up with Vook CEO Brad Inman–who said the company has more than 500 titles planned for 2010. According to Inman, the company shot between six and eight hours of footage for the Rice vook, including a New Orleans tour with her son, Rice interviews, and expert commentary.

The company recently secured $2.5 million in seed funding, and he shared some upcoming projects: “We will be releasing a vook for Seth Godin‘s “Unleashing the Ideavirus” next week, which we’re thrilled about. We have also just released “Alice’s Adventures in Wonderland,” which includes beautiful videos about Lewis Carroll and the Oxford community that inspired him to write this classic tale. We think that people are really going to enjoy it, especially as enthusiasm grows around this story with the Tim Burton movie coming out on Friday.”
