O’Reilly has released “iPad: The Missing Manual,” a 320-page book by J.D. Biersdorfer (with David Pogue), looking at Apple’s new tablet. It costs US$24.99 for a print version and $15.99 for an ebook version.

“The iPad is a brand new product that’s already sold a million units and is converting people who don’t even use a regular laptop because it’s so versatile,” says Biersdorfer. “It’s so much more than just an ebook reader and web browser, and my book shows you how to maximize the iPad’s potential to make it be whatever you want it to be.”

The “Missing Manual” promises a look at the device’s features, undocumented tips and tricks and more. For the full table of contents, sample content, cover graphic, and a video tutorial from Biersdorfer, see http://www.oreilly.com/catalog/0636920010142 .

Biersdorfer is the author of “iPod: The Missing Manual” and “The iPod Shuffle Fan Book,” and is co-author of “The Internet: The Missing Manual” and the second edition of “Google: The Missing Manual.” She has been writing the weekly computer Q&A column for the Circuits section of “The New York Times” since 1998.
