Biology Biological and Agricultural Index Plus. New York: Wilson, 1983-. An electronic index to more than 290 journals in biology and agriculture, covering topics in botany, zoology, microbiology, genetics, and biochemistry. This index provides biological citations, descriptive abstracts, and links to the full texts of articles from 45 of the journals indexed (through Wilson Web only). The work is also available in print format, Biological and Agricultural Index, with coverage beginning in 1964. BIOSIS. Philadelphia: Biosis, 1980-. The most complete index to biological literature with over 5 million records. The index provides bibliographic citations and descriptive abstracts. It is organized by subject, author, keyword, genus and species, biosystem, and concept. The index is updated quarterly. It is published semimonthly and cumulative indexes are published twice a year. The print version of this work, Biological Abstracts, provides coverage beginning in 1926. BioChemLinks.com. A portal to excellent resources in biology, biochemistry, and chemistry, with links to full-text science news sources. The links are organized by subject—general chemistry, organic chemistry, biochemistry, biotechnology, and the teaching of science—and geared toward science education and the nonspecialist. The site is the product of Schmidel & Wojcik, editorial Web developers of a number of science sites. Dyann Schmidel has also taught graduate and undergraduate courses in chemistry, biochemistry, and biotechnology. http://www.biochemlinks.com Biolinks. A search engine for a select database of Web sites in biology that avoids irrelevant or nonscientific search results. Results are listed in specific categories, such as databases, journals, and companies. Most, but not all, search results are annotated. This site has links to related areas and is updated regularly. The sponsor of this site, BioView.com, is an employment resource for the field of biotechnology that also provides industry news. http://www.biolinks.com National Center for Biotechnology Information. A federal government site that focuses on biological and medical research. The site provides access to biotechnology databases and educational resources. http://www.ncbi.nlm.nih.gov The Tree of Life. An enormous and expanding Web site of more than 1,300 schematic trees that map out biological relationships and provide information about organisms as well as detailed bibliographies. The site contains an internal search function to help users find information as well as a glossary of terms and an introduction to phylogenetic biology. It is edited by 347 subject specialists from universities, museums, and research institutions and is maintained by David Maddison at the Department of Entomology at the University of Arizona. http://tolweb.org/tree/phylogeny.html The University of Michigan Museum of Zoology's Animal Diversity Web. Provides detailed information on animals: mammals, birds, amphibians, reptiles, sharks, bony fishes, mollusks, arthropods, and echinoderms. A sophisticated search mechanism allows users to search the site by keyword and within search fields, including conservation status, reproductive habits, physical description, and geographic range. Each animal is classified by phylum, order, class, and family, and detailed descriptions are provided on everything from physical characteristics, behavior, and habitat to "economic benefits for humans." Bibliographies are included as well. http://animaldiversity.ummz.umich.edu WWW Virtual Library: Bio Sciences. An index to the many virtual library pages relating to biology, with links to biodiversity and ecology, biotechnology, botany, cell biology, and medicine. This site is part of the WWW Virtual Library <http://www.vlib.org>. http://www.vlib.org/Biosciences.html Encyclopedia of Human Biology. Ed. Renato Dulbecco. 2nd ed. 9 vols.
