Concerning WTBTS organizational manuals;
Before the current _Flock_ book, there were earlier organizational manuals. Back in the 1970s, there was the _Org_ book (_Organization for Kingdom Preaching and Disciple Making_, I think), And back from the mid 1950s there was the _Qualified to be Ministers_ book. Somewhere along the line, possibly shortly after the death of Joe Rutherford, there was a _Lamp_ organization manual.
From what I read, there was a great deal of overlap in the first three books. I don't think there were any distribution restrictions on the _Lamp_ book and the _Qualified_ book, but I do recall that in some areas in the 1970s the _Org_ book had a tighter availability. It was handed out to an interested person only when the elders thought the person was ripe for dipping and so was allowed to have a peek at the Holy Question List.
The question list in the_Org_ book was a list of belief statements used to clear baptismal candidates. I remember going over these with an elder who described the difference between "disassociation" and "disfellowshipping". He said that the former was just a relatively recent invention and the only difference between the two was a few words in the canned announcement made publicly. He told me that the main reason for the invention was to protect the WTBTS from slander lawsuits; a secondary reason was for the WTBTS to be protected from government charges of sedition and the like for punishing people who chose military service or who chose not to go to jail if they were drafted into the military.
I distinctly recall the elder relating his personal satisfaction at recent WTBTS "new light" that gave him new power to discipline members for various types of loose conduct. He was almost joyful that he could now go after a younger, single brother for the specific crime of fondling a woman's breasts. That seemed to very important to him for some reason. Maybe it was because he was well into his 60s and probably hadn't touched a young woman's breasts in four decades. You would think he'd have given up on thinking about it, but no. I hadn't thought about it at the time, but afterwards I have felt sympathy for any young women who had to meet with him on a one-to-one to cover the same questions.
