Biotechnology — Tracer Bullet 08-9

While the term “biotechnology” covers a very broad area, this guide focuses on the most recent uses of biotechnology in its four major fields: 1. medicine (vaccine development, chemotherapy drugs, stem cell therapy, gene therapy, and pharmacogenomics); 2. agriculture (genetically modified organisms and cloning); 3. energy and environment (biofuel and waste management); and 4. the bioethical and legal implications of biotechnology.

This guide updates and replaces TB 84-7, and furnishes a review of the literature in the collections of the Library of Congress on the topic. Not intended as a comprehensive bibliography, this compilation is designed-as the name of the series implies-to put the reader “on target.”
