Many years ago I donated an very old WT book to the KH library. I lady I studied with didn't want it anymore so she gave it to me. I read a little of it and found it verbose and obscure and it was like night and day compared to the religion's modern literature. However, I decided it would be a nice gesture to donate it to the KH library so that others could read it. Well, guess what happened to my book?? It did a disappearing act. I suspect it had a date with the incinerator or a shredder.
The religion simply does not want older publications around because they are a major embarrassment to them.
