I'll rise on this lure because Windy has occasionally taught me something...
Since you, Windy, started this rant about Red Books and Green Books, I started digging. I can find, as late as 1985 a Red Book and Green Book, published by the MLB Staff. This book dealt primarily with rules interpretations, similar to the JEA, BRD or J/R. I have found references to a Red Book and Green Book, but not seen them, published as late as 1999 by The Sporting News and a Mr. Melchior as the editor. However, a search of the Library of Congress online catalogue returned negative.
Pulling the resources I have, including a AAA umpire, we have deduced that the books you are referencing are actually interpretation books specific to the leagues in question.
I do have a bootleg copy of a book that covers the ground rules of each park, etc published by the PBUC. Based upon the dialogue between yourself and Mr. Ives, I have deduced that this is the "Black Book" (although mine has phone #s)
.
Is it possible that the PBUC ceased publishing seperate books and now publishes one single volume known as the "Black Book?"
If I am off base, and you are what you claim to be, please fill me/us in. I would imagine that Carl would be interested as well b/c these could be authoritative rulings previously unknown to us "underlings".
