I am teaching Professional Practice in Computer Science and, as part of preparing for the course, I read several of the available texts. While I did not find anything compelling for the way I wanted to teach the course, I was impressed by Bynum's edited
collection. It covers a broad spectrum of ethics in the field and I was able to use it to help structure the class and individual lectures.
As with many collections, the papers/chapters vary in clarity and interest but overall this book serves as a good introduction to the foundations of computer and information system ethics (making the argument that the computer does add new, under-appreciated dimensions to classical ethics). The next time I teach the course I will be using an ethics textbook and Bynum's is right near the top when I consider what to adopt.
