Query: Copyediting: A Practical Guide

This book is an absolute rip-off. Do not waste your money. It is riddled with mistakes and contradictions. I caught several mistakes in the final "test" at the end of the book. In this key section, Ms. Judd had the titles of The Columbia Journalism Review and The New York Times wrong, and those weren't the only errors. Such sloppiness in a copyediting book is outrageous! Also, if you are interested in proofreading, there is almost nothing here for you. This woman is a fraud! As I said, save your money. Get the style and usage manuals, and study them yourself.
