Tiny and unsatisying
This isn't a book or even a booklet as much as it is simply a tract on how to evaluate and formulate an argument for the purposes of research or writing a paper. It's more like something you'd hand out to high school students. And for that it's quite good. But like I mentioned, it's more of a tract. It's very short, not in depth at all, and overall leaves you wanting much much more. For 99 cents, it's fine. But I rather would have not bothered with it and bought something more thorough.
