Nicholas Carr's bestseller The Shallows has become a foundational book in one of the most important debates of our time: As we enjoy the internet's bounties, are we sacrificing our ability to read and think deeply? This 10th-anniversary edition includes a new afterword that brings the story up to date, with a deep examination of the cognitive and behavioral effects of smartphones and social media.

Nicholas Carr is the author of The Shallows, a Pulitzer Prize finalist, The Glass Cage, and Utopia is Creepy. He has written for the New York Times, the Wall Street Journal, Atlantic, and Wired. He lives in Massachusetts with his wife.
