Maybe this is bad to say, but whenever it comes to "me needing a book" the first thing I do is google "$BOOK_NAME pdf" and check it out. There is a catch though.. if I find the book a good asset, then I make sure to buy it, but otherwise it just doesn't make sense to gamble $20+ on a book that will be outdated in a year, unlike literature.
