'The 21st century has been a time of huge change for the book, but it has left us with more questions than answers. However in this thought-provoking and informative monograph, Phillips and Kovač uncover what makes the book tick, both today but also over the deep expanse of reading history. They uncover the big questions around the book, whilst offering original answers to what, in an age of transformation, is so significant about this slippery but essential form. Is this a book? is the best single volume on the book there is.' Michael Bhaskar, Co-Founder of Canelo and author of The Content Machine
