Like other reviewers, I found the errors which fill this book made many of her examples confusing. The errors also make me question the credibility of this text. This is the third edition; there should not be as many as four errors on a single page.Also, her tone is condescending at best. I'd rather not be spoken down to by someone who has produced such a poorly copyedited text...about copyediting.This book is a required text for a graduate class (in an English and Publishing program) and we all spent a fair bit of time complaining about it.In spite of this, it is reasonably helpful. I would, however, recommend purchasing stylebooks instead or at least in addition to this text.
