An information transfer product of the Wildlife/Fisheries Review database. Annually over 24,000 citations from over 1300 journals, several hundred books and symposia, and several hundred theses and dissertations are added to the databases. The scope of the databases are primarily wild vertebrate biology, ecology, and management and related disciplines. NBS offers four SDI literature packages: wetlands, endangered and threatened species, contaminants, and aquaculture. Materials must fall within the scope of coverage of the two Reviews i.e., wetland literature pertaining directly to wild vertebrates, wild vertebrate endangered species, the effects of contaminants on wild vertebrates, and aquaculture of fin fish. These four SDI packages were made available for a six month test period ending June 1995, and future distribution are to be evaluated.
