Where Can I find Sources for Learning LaTex?

the_2nd_coming asks: "I am currently in college and I am majoring in math and computer science. Writing papers in Word and OpenOffice, while not a pain, is slow work due to formating. I have learned that LaTex is used for writing Math and Science papers a lot and once learned makes writing papers quick. I have found few good comprehensive resources on the web, and few books in the book stores. I was amazed that O'Reilly did not even have a book on it. What good sources are there that can teach me LaTex for Mathematics and BibTex?"
