BIOSIS indexes items to a variety of subject fields to enable comprehensive and
precise retrieval. Regardless of whether you simply search for keyterms or take
advantage of searching the individual descriptor fields, it will be important to know
which information is searchable.
s
Broad topics are indexed to Major Concepts and Concept Codes.
s
Specific topics (such as named diseases, specific chemicals and/or drugs,
organisms, etc.) are included in the title and keyterms.
s
From 1993- additional descriptor fields are available to allow more
precise retrieval. Prior to this time all specific topics were indexed to a single
subject field. However, terms included in the title were not repeated in the
keyterms, so it is essential to search title and keyterms prior to 1993.
