There is a video on youtube by "shazoolo" which shows the differences between the '68 Truth book and the '81 Truth book.
It exposes how the Society has tried to cover up the fact that they did in fact predict 1975 as the end of the world.
I have a '68 Truth book (which I have "borrowed" from the Kingdom Hall library). Can anyone hook me up with an '81 version so I can show others the indisputable evidence?
I don't know if you can order the Truth book from the Hall anymore.
