Welcome,
I am quite new here too, and I think it’s great to look into the older publications no longer provided by the WTS. The WT frequently quotes old catholic or atheist printings and teachings, which I think anyone is free to do.
By the way, the new publications and “new light” is enthusiastically discussed here. And posters like “blondie” discuss the latest WT articles with much participation of others. Keep reading and you will find interesting discussions about the old and the very new development of WT teachings.
