Just as more and more people are turning to e-readers, Oprah Winfrey is bringing her famed book club to the digital world. "I was reading this book . . . and I was like, 'Where is "The Oprah Winfrey Show" when you need to announce and tell everybody about this book? I need the book club,'" Oprah said in an introductory video. Aptly renamed Oprah's Book Club 2.0, the new program will include digital content, like a reader's guide and Oprah's notes on her favorite passages from the book, plus Twitter and Facebook conversations with Oprah and the author.
