There are also many informative threads here, you just have to look and read.
The problem there is, a lot of users in here do more of the interaction than reading. How do I even know what next to talk about if I don't read?? Things don't seem to workout for me just like it does to everyone else that don't even give a f*ck.!
We all know why he's asking for an A to Z resource right?

I suppose it is taking a bit too far, I was more rather curious. It would kind of be cool though. A super in depth history book on gambling if you will.
