"The book is like the spoon: once invented, it cannot be bettered". (Umberto Eco). These days it is almost impossible to get away from discussions of whether the 'book' will survive the digital revolution. Blogs, tweets and newspaper articles on the subject appear daily, many of them repetitive, most of them admitting they don't know what will happen. Amidst the twittering, the thoughts of Jean-Claude Carriere and Umberto Eco come as a breath of fresh air. There are few people better placed to d iscuss the past, present and future of the book. Both avid book collectors with a deep understanding of history, they have explored through their work the many and varied ways ideas have been represented through the ages. This thought-provoking book takes the form of a long conversation in which Carriere and Eco discuss everything from what can be defined as the first book to what is happening to knowledge now that infinite amounts of information are available at the click of a mouse. En route t here are delightful digressions into personal anecdote. We find out about Eco's first computer and the book Carriere is most sad to have sold. Readers will close this entertaining book feeling they have had the privilege of eavesdropping on an intima te discussion between two great minds. And while, as Carriere says, the one certain thing about the future is that it is unpredictable, it is clear from this conversation that, in some form or other, the book will survive.
