This is actually old news, as Lulu.com has been around for a while (Leigh Blackall used it to publish his Teach and Learn Online book). And as Brad Jensen noted on DEOS Sunday, Amazon has it's own version, BookSurge. But this service, Blurb, seems to be new. "Blurb and its ilk are democratizing a tired oligopoly, opening up the pipes to... everyone, really. Want to publish your treatise on the government's extraterrestrial conspiracy? Sure! Your kid's refrigerator art? It's a coffee-table book!"
