The trouble is, books need help far more urgently than films and music. Despite all that has been said about impending disaster, both the film and music industries have relatively easy routes to long-term survival. 

Music will go back to its roots -- live performance. In fact it already has. It's no bad thing. And a night out at the movies will remain a favourite activity for 16-24 year olds for as long as we can foresee. The cinema box office is healthier than ever.

It's books I worry about. I can't see a way forward. We are relying entirely on the hope that sufficient people feel a moral imperative to pay. But I know few people under the age of 40 who pay for their recorded music... (I am well over 40, which is probably why I worry about these things).

My suggestion: all industries that sell digital entertainment seem to be heading inexorably towards an all-you-can-eat model. Why should books be any different? So we need commercially-driven libraries -- a literary Spotify.
