Biomedical Ethics Reviews • 1987 is the fifth volume in a series of texts designed to review and update the literature on issues of central importance in bioethics today. Three topics are discussed in the present volume: (1) Prescribing Drugs for the Aged and Dying; (2) Animals as a Source of Human Transplant Organs, and (3) The Nurse's Role: Rights and Responsibilities. Each topic constitutes a separate sec­ tion in our text; introductory essays briefly summarize the contents of each section. Bioethics is, by its nature, interdisciplinary in character. Recognizing this fact, the authors represented in the present volume have made every effort to minimize the use of techni­ cal jargon. At the same time, we believe the purpose of pro­ viding a review of the recent literature, as well as of advancing bioethical discussion, is admirably served by the pieces col­ lected herein. We look forward to the next volume in our series, and very much hope the reader will also.
