Like everyone else has stated...get a reputable manual from a bullet or powder manufacture...I have a shelf full of books old and new. I like Nosler, Hornady and Speer books personally...but also have several older books from Lyman and others. As RR said, read the front sections of the books first...I also like the Hodgon website as well. 2 primary rules of reloading IMO...Patience and Process...
