If you are looking for a topical discussion of technical and business writing, I think you can do better.That said, the book is a quick, informal, benign read. Though it purports to be updated, some of the essays go back to the early 60s.Some of the techniques discussed don't quite agree with the methods discussed in Mike Markel's "Technical Communication" or Carolyn Rude's "Technical Editing."If your instructor requires it for a course, buy it used. You'll likely sell it to someone else when you're done, as I will. It makes no sense to lose that much value on the resale.
