<yawn> Sorry Dennis, you are stuck in the present. Yes books are currently published in paper but not for long. It is inevitable and unless the publishers realize this and change quickly new businesses will take there place. It's going to happen way faster than you seem to think.
The music business is in shambles at the moment, the publishing industry will be in another five years. It is already going down hill and has been since before TV took over as the primary home entertainment venue.
Not much time left.
P.S. You seem to be stuck in the Independent publisher vs the mega publisher mindset. That's not necessarily what I'm saying at all. The publishers are more likely to be replaced by something like Amazon than a bunch of ants.
