Here are three new Tracer Bullets that were recently released by Science Reference Services, Science, Technology and Business Division at LC.
Not intended to be a comprehensive bibliography, this guide is designed–as the name of the series implies–to put the reader “on target.”
Buildings are fixed structures for human occupancy and use. Building engineering includes the use of engineering principles and practices in the design, choice of materials, construction, maintenance, and the safety and security of buildings. This guide includes resources related to the design and construction of buildings, but emphasizes historical resources.
This is a guide to sources relating to the history and contributions of women in the fields of science, technology, engineering, mathematics, and medicine (STEMM). Also included are resources on present-day women scientists, as well as materials on the current status and concerns of women in the sciences. Related titles are Science Tracer Bullet Career Opportunities in Science and Technology (TB 05-4), Science Reference Guide Girls & Science Education: How to Engage Girls in Science, and the bibliographies and guides listed in Science Subject Guide Biography, History of Science. An update of Tracer Bullet 90-6.
This guide offers a systematic approach to a wide variety of published material in the Library of Congress on endangered and/or threatened species of animals and plants. Extinction of species has occurred as a natural process since life began on Earth, but human activities have greatly accelerated the rate of extinctions in recent years. Among the many factors that may contribute to the disappearance of a species are habitat destruction, overexploitation, introduction of exotic species, and climate change. Endangered animals face extinction in all or a part of their ranges unless specific measures are taken for their protection. Threatened animals are likely to become endangered in the foreseeable future. Endangered mammals and birds have received the greatest amount of attention in conservation efforts to date, but there is a growing recognition of the importance of endangered amphibians, reptiles, fish, and invertebrates, so these animals are likely to receive more attention in the future. Although plants are absolutely essential to human and animal life, endangered plants have received relatively little attention compared with that given to endangered animals.
