I just went to a book signing tonight at a local independant bookstore. There were enough bibliophiles there that I believe real books will continue for a long time. But they'll become more expensive and less mass market.
For the record, the reading was Bonnie Jo Campbell "Once Upon a River". She was the first author or anybody I ever sent a fan mail to after reading her first novel, Q Road. I have now sent two fan emails, so she's a member of an elite club.
