Here's a question for your blog - do writers get invited to book shows like Frankfurt? Only the huge names, or a wide variety of authors? Feed the dream - show me what it's like on the other side of the published/unpublished divide.
First of all, don't think about Frankfort. It's a show for foreign rights. I paid no attention to anyone other than people who were buying rights. If there were authors there, I shoved them aside as I raced after the fiction buyer from RandomHouse-Macedonia.
If you want to see what publishing is like, get credentialed for Book Expo America. It's in DC next year and it will cost you about $125 for three days. Trust me, you'll go home sobbing. It's utterly overwhelming to see how much is published.
Or, if you want to see the people on the front lines of book retailing go to the LOCAL Booksellers association trade show: Southeast Booksellers Trade Show, Pacific Northwest Booksellers Trade Show, Norhtern California Booksellers Trade Show, New England, Great Lakes, Texas...and on and on. There's where you see the folks who will sell YOUR book. Your local market is your friend.
And if you want to really feel the love, go to the Library Association convention next June in New Orleans. Librarians are freedom fighters not to mention super heroes for books. Some of them even travel with capes and bulletproof brassieres.
Ignore Frankfort. That's only for gin soaked, abuse hardened agents who have Hell on a leash.
