A shame, for serious researchers, but increasingly irrelevant to freeing the JW's of today, who, and of course I generalise, are illiterate and extremely lazy mentally.
When I first left the religion in 2008, I researched the History of the religion, and its history of ever-changing Doctrine.
A resource such as this would have helped me no end, but I am a rarity, I left because I am a lover of truth, and false doctrine was what got me to leave.
99.99999% of JW's don't care about Doctrine, and care even less about Truth.
