Even after 30 years, this book is still the best book on technical report writing I have found. It contains techniques that I have seen nowhere else and that are consistent with everything I know about organizational and scientific communications (in which I have a graduate degree). It is NOT a book on technical report writing written by typical English professors with degrees in literature who believe that writing in the tradition of the Humanities is the only tradition of writing that matters. Technical and scientific writing are distinct from writing in the Humanities, and Mathes and Stevensen are well aware of the differences. Their advice is based as much on research into how reports are used as it is on traditional written communication strategies.
