The era of the printed book is at a crossroad. E-readers are flooding the market, books are available to read on cell phones, and companies such as Google, Amazon, and Apple are competing to command near monopolistic positions as sellers and dispensers of digital information.

In this collection of essays, Robert Darnton-an intellectual pioneer in the field of this history of the book-lends unique authority to the life, role, and legacy of the book in society.
