Thanks for the link to the Scalzi post. Really terrific stuff, and a great twist in the ending.
I have no doubt there will always be publishers, and editors, researchers, fact checkers, the edifice of publishing isn't going to go away. But even though I've spent a lifetime as a fan of the printed book, of typography, and have built handpresses and set type by hand, and amassed a library of books on books (ever read the Anatomy of Bibliomania by Holbrook Jackson? Good read.) I don't think the change can be stopped. The pressure of diminishing resources, the waste involved in book production and distribution and the unleashing of text in electronic formats seem like overwhelming reasons the printed book is in trouble. It may survive, marginalized, and the process could take a very long time, but it seems as inevitable as the closing of Blockbuster stores did 5 years ago. The writing was is the wall.
