I only have one copy of "Life Everlasting in the Freedom of the Sons of the True God" for use if I ever come across Witnesses unfamiliar with 1975. Oddly enough, I remember a circuit overseer during pioneer school who spoke very highly of the book and recommended it to us, with the offhand remark that "some of it is a little out of date."
I was considering compiling a binder of material on different subjects like 1975, the UN NGO, etc, but honestly that would require more effort than I'd like to give for this damn cult.
