Prior to 1998, organisms were searched using the Biosystematic Index and the
Generic Index.

The Subject Index
The Subject Index allows you to locate references by specific terms (key terms)
which are used in the author's title, or added by BIOSIS indexers to enhance or clarify
the title.
The Subject Index has been redesigned for 1998 with an easy-to-scan back-of-book
format that replaces the Key-Word-In-Context (KWIC) index.
Within the Subject Index, key terms are arranged alphabetically and are followed by
drug modifiers (when appropriate), Major Concepts, and keywords that best describe
the context of that term in the source document. The first Major Concept is the primary
Major Concept which gives the most relevant description of the broad focus of the
document. It is also the Major Concept the abstract (BA) or citation (BA/RRM) would
be found when scanning the abstracts, meetings, etc., sections.
Conventions
s
All significant words used to describe the original document appear in the Subject
Index, including genus species names, common organism names, geographical
regions, and scientific and commercial drug names. Note that common organism
names are included as provided by the author in the original document.
Prior to 1998, Latin names of organisms appeared only in the Generic Index.
v
s
Key terms that are organism names or geographic terms may appear with classifiers
in parentheses beside the key term.
s
For entries appearing under the same key term and sharing the same drug modifier
and/or primary Major Concept, only the first occurrence of each appears. All subse-
quent entries sharing the drug modifier and/or primary Major Concept are indented.
s
When appropriate, identifiers for Review Article (R), New Taxa (N), and Fossil Taxa
(), Uncertain Identification (?), and Drug Affiliation (D) appear in the right margin
following the reference number.
s
Words whose significance are improved by pairing (e.g., GUINEA-PIG, CARBON-14)
are kept as single key terms.
s
Numeric key terms (e.g., chromosomes, drug codes, cell lines) appear after the final
entry for "Z" in the index.
Prior to 1985, compound terms were segmented into two or more parts. For
example, the word echocardiogram appeared in the Subject Index under both
echo and cardiogram. In 1985, the practice of keyword segmentation was
discontinued.
