Whenever I find imported books of his, they're always slightly warped, and the pages have been gently abused along the edges as if someone had applied a cheese grater to portions of them. I know in my mind that these are probably just books that got abused in stores and couldn't be sold (in the UK, anyway), but I like to think the damage they suffered was sustained in transit to America via Valiant Book Smugglers, seeking to bring the works of Terry Pratchett to the unenlightened.
In other Terry Pratchett news, I found this quote in Strata :
"I'm proud to be human. Make no mistake! As for the other," he said, turning, "just because you're paranoid doesn't mean They aren't out to get you."
This book was written in 1981, which makes this the earliest version of the quote I know of -- is this a real live pterryism?
