I need current information, not outdated information regarding the origin of the organization
A funny thing about history. The farther away from the event you get, the fuzzier the "current" information on the past becomes. I'll give several modern examples. Once in a while a wildly popular modern figure will suddenly die. The public is bereft, and questions are asked. Some people cannot reconcile themselves that these people are gone. For example, we have Marilyn Monroe, Elvis, John Kennedy, and Lady Diana. Within a short time after their passing, questions are asked about the details of their death. Even if their death was public, televised, and easily provable. People start asking, was there foul play? Maybe they didn't die, but live in a secluded monastery in Pasadena?
You don't get closer to the truth by reading modern interpretation of past events, but by getting as close to the source as possible. A secondary verification comes from peer reviews and cited sources. Does the author have a reputation for objectivity, careful research? Can you double check his sources? It does not matter if his argument SOUNDS good. Can it be double-checked?
For the origins of the Watchtower Bible and Tract Society, I find the Bible Students material to be better preserved than what the WTBTS revises every year. http://www.biblestudents.net/history/ You may also enjoy reading early Golden Age articles to get a sense of what it was like to be an early Jehovah's Witness. http://www.premier1.net/~raines/intro.html
p.s. I believe there is only one God. If there is only one, why do I need to prove that MY god is the TRUE one? As soon as I claim exclusivity, I admit there are other gods in this world. I won't.
