Marilyn was the developmental editor on my first book, a major introductory textbook on information systems. While she did not start as an expert on the subject matter, she was highly effective in helping me channel my ideas into an understandable form. She was pleasant and easy to work with, while also providing extensive feedback about strong points and weak points in each draft. In addition to contributing significantly to a successful book, she taught me enough about writing a book that I needed very little developmental help in the subsequent editions and later felt totally comfortable writing another book on my own. I recommend her highly.
