Update: Martin sez, "Unfortunately, this doesn't apply to the German libraries as a whole, but only to the Deutsche Bibliothek, the German analog to the US Library of Congress."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
