And another note - I have yet to find anyone who prefers ebooks over the paper version, except maybe when traveling. I have access to hundreds for review, but I won't read them unless I'm out of paper, which isn't likely to happen in my lifetime. So I don't see the paper version disappearing anytime soon.
On the other hand, technology now enables more authors to self-publish and self-promote their books. I've been contacted first hand by many authors looking for reviews - that never used to be possible.
And honestly - while I LOVE browsing through a bookstore, I hardly ever buy there because I can buy everything cheaper at Amazon etc. - and I get most of my wish list from online recommendations - not in bookstores. That's me...
