Reply to References for learning how to DJ

Guys and girls, I was trying to get a solid idea of djing I believe I'd rather had a chance to read about gears.
Currently I own Novation Twitch and Mac pro. I was trying to find some good references about learning DJ but threads that are posted here weren't helpful too me.
Can you recommend me some book or references to feel what djing is?
It seems to me that people posting things all look like pros.
