It's remarkable how seldom we encounter consequential disagreement between an author and an editor. We always try to put our criticisms in context and support them with specific examples. An author is of course under no obligation to follow a suggestion or to accept any criticism we make. We’re generous with our suggestions, careful to separate problem and solution, and we’re always open to discussion. In the unlikely event of a dispute, the best thing to do is call the Tucson office.
