For a long time I had access to the 17th edition minus a volume or two. I had no idea that the 11th edition was considered among the finest examples of the form. I had no idea anyone rated such things.
I did know what a treasure trove the 17th was and wandered through it often and for hours on end. Things like Terrye's Sin Eaters... No Pluto... things missing by taboo and so much that is taboo today.
I can smell it. I wonder if it still is where it was.
