It's very difficult to edit one's own work. That's why there are editors and proofreaders. Good editors catch the simple, and not-so-simple, mistakes and problems inherent when using written words to convey meaning. Good proofreaders catch the mistakes authors and copy editors miss and mistakes introduced during page layout. As a writer, I've edited my own and others work for over 15 years. When editing I help my clients better communicate their intended meaning to their audience. I ensure authors look professional to their readers. Over the years, I've edited material from brochures and white papers to websites and books. I'm familiar with the Chicago Manual of Style and have immediate access to the Associated Press Stylebook on my bookshelf for authors who need to conform to the latter's style.
