Ummmmmm, thats what happens when u put something on THE WORLD WIDE WEB !
Imagine a few dozen people copying them or displaying them when they have diss-appeared out of site. Nahhhh, that will never happen when u put something on the web ! 
Next, if u produce a CD and sell it, what will you do with the next piece of modern technology called a DVD BURNER. I understand this fellow has been displaying these for a while and he has spent 15 years on it, but this technology was copied when photo copiers were around, then came computer flat bed scanners, then came email. Technology is against you from them being copied, but the same technology (called the world wide web) is how so many people know about them. This is where u cant have ya cake and eat it too ! Protecting Intellectual Property these days is almost impossible. Every industry suffers now because of it.
Clay shld tell the world what he wants to do with them, and try real fast on making a buck if he can. Seems the horse has bolted.
I HAVE AN IDEA THAT MIGHT WORK. SOMEONE EMAIL IT TO HIM ! 
If Clay did a book and added heaps of photos, and did a bit of a story with his version of his last 15 years work n experiences in the pinball industry, this is how he could make a buck and stop just the technical stuff being copied. Call it "Pinball Compendium meets great in depth technical data and pinball stories" all wrapped up in one hard cover colour book.
Now, that would sell and u cant really copy a hard covered 100 page book with a electronic coded key (like Microsofts software key) which then gives u membership to his guides. He has to get a bit creative to make his product fit n work the modern day and the challenges that come with it ! 
Modern technology makes going to print very easy and only a few grand to get the first batch printed. I have a friend who publish's books with a few of the biggest book companies in the world. it wouldnt be that hard for Clay to do something that would help his cause $ and still get money for the guides. (that will be 10 percent Clay for that great advice) 
That sound very sensible to me and to probably 99.999% of people, but there seems to be something funny going on with all this that Clay is not letting on.
I obviously haven't met they bloke, but from the few emails he has sent me he seems a bit odd.
Here is the last email he sent me:
thank you very much for removing them.
i really appreciate it. i know you were just trying
to help the community.
again thank you.
