To mark the 50th anniversary of the publication of Betty Friedan's iconic feminist manifesto, The Feminine Mystique, W.W. Norton is releasing a commemorative edition, with a new introduction by New York Times columnist Gail Collins and an afterword by best-selling author Anna Quindlen. O asked Arianna Huffington, presiden and editor in chief of the Huffington Post Media Group, to share what the book means to her.

"The Feminine Mystique forever changed the conversation as well as the way women view themselves. If you've never read it, read it now and reflect on what our mothers and grandmothers were feeling at the time. It's a great moment to celebrate this milestone work, which fundamentally altered the course of women's lives."
