The library, amazon.com, try to find bookstores that's geared towards what your searching. Plus, I'd say its also good to segment the shyt. I've always felt the way you feel now, since I was a little kid I had this need to understand what the hell was going on around me. At this stage of my life its become more or less answering why the world is how it is, why black people are in the position they're in now, etc etc. Any questions you have can be found in a book, but be a critical thinker...I can't stress that enough.
