BIOSIS Previews® is the world's most comprehensive reference database for life science research. It covers original research reports and reviews in biological and biomedical areas. Coverage includes traditional areas of biology, such as botany, zoology and microbiology, as well as related fields such as biomedical, agriculture and ecology. Interdisciplinary fields such as medicine, biochemistry, biophysics, bioengineering and biotechnology are also included. Nearly 5,500 serials are monitored for inclusion. In addition, the database covers content summaries, books and meeting abstracts, papers and posters. Content summaries include notes and letters, technical data reports, reviews, U.S. patents from 1986 to 1989 and from 1999, meeting reports from 1980 to present, bibliographies, nomenclature rules, and taxonomic keys. The BIOSIS Previews database includes the contents of Biological Abstracts (1969 to present), Biological Abstracts/RRM (1980 to present) and BioResearch Index (1969 to 1979). As part of the Web of Science (WoS) BIOSIS Previews permits convenient use of Biosystematic Codes/Names for searching groups of organisms as well as the use of Concept Codes/Headings that represent broad subject areas.
