(Ypsilanti, MI USA)
This was quite helpful while taking a journalism course. It takes a few minutes to understand the layout of the book to lookup things, but once you get it, it's easy.
I think this book helped raise me a letter grade in my course. Anyone taking a journalism course with a strict professor or planning on entering journalism should get a copy. My textbook had a reference in it, but it was quite small. With the low cost of this book, you can't go wrong.
If you're taking the course without an intent to go into journalism, check to see if you can use copies from the department first.
