Back when I was in I donated an old WT book from the very early days to the Kingdom Hall library. It disappeared never to be seen again. I believed back then, as I do now, that their old writings are an embarrassment to them.
I am not surprised that now they are positively hellbent on getting rid of ALL old books and other publications because they don't want any evidence around to contradict their teaching of the day.
This means anybody on the forum who has old publications should hang onto them for reference purposes!
