A 184 page book, published this month, takes a case study approach to the practice of ethics online. The table of contents suggests that it covers a fairly wide range of topics, given its (relatively) small size (for a technical book).

"The exponential growth of the Internet is one of the most remarkable technological phenomena of the last century. As the virtual world begins to displace the physical one, we must grapple with many controversial social problems. Cyberethics: Morality and Law in Cyberspace takes an unbiased look at four perennial issues: free speech, intellectual property, privacy, and security. This book draws from the work of legal scholars and philosophers to develop a comprehensive framework that will facilitate analysis of the moral and legal dilemmas that arise in these four areas. Cyberethics is quite versatile, and can be used as a companion text for law, ethics, and policy courses taught in law schools, schools of management, and philosophy departments. It is ideally suited for computer ethics and Internet ethics courses."
