After many months (months? weeks, at least) of waiting, the Pig book is searchable via Google books. It's kinda silly given that you can view it for free right here, in a dozen languages, but it's still nifty.
Also, it appears that Amazon may or may not have found the two missing copies I sent them back in August, in which case you may or may not be able to order them from there. I only discovered the change in probable status because Google linked me there :)
Stumbling back appears to be an apt description... I am not even close to fully-functional yet. I shall update again soonish.
