Just an initial thought. Having to produce books in paper is so limiting because …

• The set-up costs are never that low.
• You never know how many to print in advance so you either overstock or run out.
• There is never enough bookshelf space in any bookshop to hold more than a fraction of what’s available.
• Paper doesn’t keep that well because of low levels of acid in most papers; they very slowly rot away – no legacy there!
• They are really bulky and heavy. A lightweight e-book reader can carry dozens of books and fit into one large pocket.

And so it goes on …

Whereas, by comparison, e-books are easier to produce, store and distribute.
