Maybe three and a half stars. It would probably be a good guide for students writing, which is what it is intended to be. I actually sort of disagree with a couple of things he says here, about not using a thesarus and some of the things about how to create non-discriminatory language. I guess that's why I teach my own class in writing in psychology and use the guidebook some colleages and I wrote.
There are some very nice tidbits here though, for sure.
I read this book with my research methods class. I wasn't impressed. It was dated (even though it was a new edition - it hadn't been updated nearly enough). Next spring semester, I'll be looking for a different text.
