We now have access to Biosis Previews from 1969 to the present as part of the Web of Knowledge database.
BIOSIS Previews is the world’s most comprehensive reference database for life science research. It covers original research reports and reviews in traditional biological and biomedical areas. It also covers references to primary journal literature on vital biological research, medical research findings, and discoveries of new organisms.
It indexes nearly 6000 journal titles.
You can search Biosis Previews separately or combine searches with the other databases on Web of Knowledge. Coming soon on the same platform: the Biosis Citation Index!
