This book was a required text for an introductory Technical Writing course. I would not have purchased it otherwise. The emphasis of the book is on writing standard business reports and does not cover the full scope of modern Technical Writing. (no white papers, no procedural manuals, no scientific articles, etc.)The book is wordy and poorly organized. Several editing errors were spotted.I personally feel there are far better references than this for technical writing.Try:The Non-Designer's Design BookUntechnical Writing - How to Write About Technical Subjects and Products So Anyone Can Understand (Untechnical Press Books for Writers Series)Microsoft Manual of Style for Technical Publications Third Edition
