Just for your information, _I_ am the person who first released most of that information in free digital format many years ago. Search this site for "Watchtower Bookshelf CD" if you are interested.
I don't distribute anything for free anymore because I got tired of sending a free CD halfway around the world at my expense and then discovering that the person who got it was selling copies of his free CD on eBay.
I digitized a lot of other stuff too, then was inspired by the author of "Captives of a Concept" (Don Cameron) to get into the "replica reprint" business.
It's a GREAT way to make A LOT of MONEY FAST, if by " a lot" you mean $20 and by "fast" you mean twelve years. :)
...but I do it to meet chicks, and the occasional duck.
Checking your link, I see that is not my stuff. It looks like it may be material from the Bible Students, who still think that Chuck Russell was the cat's meow and that soon their loopy graphs will become relevant in the real world.
The stuff I did was more 50s and 60s WTB&TS stuff.
It is not too late to join the UADNA team!
