Every editor edits. That is, every editor determines what will and will not be published, broadcast or placed on the web, and how it will be presented. This book stresses the skills of editing, but learning those skills without a thorough understanding of the philosophy of editing would be like learning to hit a baseball without knowing why hitting is important. Why bother to hit if you don’t know to run to first base? In editing, it is important to know not only when a change in copy should be made but also why that change should be made.
