Correct...I've already got the thick, blue hardcover edition that is successor to the Scinta book. The "pink book" is what I'd like to get my hands on, circa 1970 from the US Government Printing Office, which no longer lists it.
Government published material is in the public domain, so I would be more than happy to pay somebody for the copying, postage, and their time if I could get one somewhere.
Thanks!
