College-level audiences with very strong holdings in science, technology or medical studies must have the 4-volume ENCYCLOPEDIA OF SCIENCE, TECHNOLOGY AND ETHICS: it will reach these disciplines and more equally well, holding strong references on topics ranging from biology and medicine to business ethics, astronomy and public relations, and politics and social values. Much more than a compendium of topics and definitions or examples, articles provide detailed discussions linking ethical and social issues to advancements in technology, challenges of working with it, and more. From philosophy to bioethics and beyond, no serious college collection should be without.
