A New Science Tracer Bullet from Library of Congress: Economic Botany: Useful Plants and Products

New From the Science Reference Section at LC.

This guide offers a systematic approach to the wide variety of published materials on the use of plants by people. Economic plants are defined as being useful either directly, as in food, or indirectly, as products we use or that enhance the environment. Plants are essential to life on earth; they produce the oxygen we breathe through photosynthesis and provide much of the food we eat. Some species provide medicines and promote healing, others are used for insect control or to conserve water. Plants with dense root systems prevent soil erosion and those with brightly colored flowers attract pollinators. Plants have been used to control body functions and fertility, to poison, and to make clothing, paper, and rubber. The guide includes references to materials on food plants, fiber plants, dye plants, edible plants, medicinal plants, oilseed plants, as well as plants used in ceremonies, cultivated for commercial purposes, or used as shelter.

The Tracer Bullet is Organized in the Following Sections:
