Query: Extremely Useful

I'm starting my second year of law school. I got this book near the end of my first year, and it proved to be an invaluable tool for editing journals and working for law firms over the summer. I wish I had this earlier.As a side note, I would strongly recommend this book over Garner's American Usage if you are in a legal field. Even non-legal terms are covered in a way more useful to legal writing.
