Why doesn't Amazon sell trade paperbacks? A book in the trade paperback edition is the same size as the hardback edition, but has a paper back. It is therefore significantly cheaper than the hardback edition, and has the benefit of allowing those with less money (i.e. students) to read a book immediately on its release, without having to wait for the paper back, usually released a year after the initial publication. Publishers often release trade paperbacks simultaneously with the hardback edition. I've seen the trade paperback edition of this book, Stiglitz's 'Freefall' in bookshops in Dublin, but for some reason Amazon is only selling the hardback edition. I noticed the same with Christopher Andrew's 'The Defence of the Realm'.
