You of all people don't need reminding of the changes in dissemination of reading material, but for years now I have been asking "How do you find out about what you want to read?" without much response.I'm reduced to word of mouth, a little publisher news, and the occasional huckster table, although with the unicorns, sidearms the size of Volkswagons, and sparkly vampires, "do you have a science fiction section?" has worn thin.
