Here is a list of very useful books to reference and gain in knowledge. But I must give you a heads up because some of these require a college level education to fully apreciate and understand them. Try to get these books from either your local library or from a book store and try to read them thoroughly; I prefer to buy them because then I can have them in my posesion with no time constraints and can take my sweet time in reading them. I will also provide free links to scholarly articles where possible since these are very hard to find because usually you are charged for such a service.
          And also the next time you want to do a quick re-search on something from the net don't use regular google because you will not get what you seek and often you will come across biased and unscholarly material. Use this instead: http://scholar.google.com/ And also; EVERY book, essay, poem, or exerpt that I post on this bibliography is of a scholarly nature. When they do not deal with a scholastic subject like Anthropology or Science they will be artisitical and literary such as poems or essays. I also don't advocate opinions, biased emotions, or prejudices. I am tolerant of opinions but only as far as they are founded on something solid or plausable. Emotions do NOT constitute as foundations here beyond their inspirational purpose.
