In an attempt to step back and reconsider ethical implications raised by new library technologies, this article looks for indications of whether new technologies have indeed created new ethical dilemmas in librarianship, either by raising totally new issues or by substantially changing the nature of previously identified issues. First, background information about general computer ethics and library ethics is reviewed. Next, arguments about the novelty of the general issues raised by technology are considered. Finally, specific cases of new ethical issues in librarianship are evaluated, and implications for the profession are discussed.
