Query: Stay AWAY!

This book is a looseleaf collection that does not teach anything at all about proofreading. I had hoped to see some pages of marked text. Nothing! The papers have an abundance of errors for you to proofread for yourself, but not a word about how to do it. The collection was designed for use with an instructor who would tell you what to do, leaving you to practice on the sheets that comprise the book. The material is for test purposes only; there is no instruction. I urge the writer to issue a new addition with the ANSWERS, i.e., with the same sheets MARKED, rather than left for the reader to mark.
