The real effect of the WTC calamity has been depressed spirits, anxiety, and uncertainty among publishers, and of course those emotions are not restricted to publishers.
We are forced by the major publishers to include electronic rights in the contracts we make with publishers for new books. And there's very little we can do about that.
