The authors analyse the impact of the new digital paradigm of the book will have on the architecture of the sector and the agents presently involved in the value chain. The new forms of creation, consumption and content sharing are causing the world of the book to look for sustainable ways to reconfigure an industry which has never undergone such profound changes since it emerged more than 500 years ago. The text encourages the sector to reflect deeply and accept and embrace the changes that can already be seen on the horizon. The authors put forward ideas and reflections that, while recognising reasonable doubts about many of them, constitute a serious wake-up call in relation to the need to reflect on a sector being pushed towards profound renewal.
