Content:
The CVOC Vocabulary database gives you access to the database of
controlled descriptor terms used in the CAB International databases
of agriculture and allied fields.
Typical of a thesaurus, CVOC lists the terms themselves, together
with their broader, narrower and related terms, as appropriate.
In addition, synonyms and scope notes indicate the concepts that
are covered by the term.
CVOC is an invaluable aid to searching the CABI family of databases,
which are CABI, VETS, HUMN and TOUR.

Searching CVOC:
It is most likely you will be searching CVOC to find which terms
have been designated as preferred terms in your area of interest.
Therefore do not qualify your search to any particular paragraph.
Then you will be able to see if your term is a bona-fide descriptor
term or whether you are referred to other, preferred terms. You will
also be able to see if there are broader, narrower or related terms
that may be more appropriate. For example:
1_: ..root embryo
This will display a list of all terms in the vocabulary file
containing the word 'EMBRYO' i.e.:
R1 25 DOCS EMBRYO
R2 1 DOC EMBRYO-ABORTION-PLANTS
R3 2 DOCS EMBRYO-CLONING
R4 2 DOCS EMBRYO-CULTURE
R5 1 DOC EMBRYO-DEVELOPMENT
R6 1 DOC EMBRYO-GROWTH
R7 3 DOCS EMBRYO-IMPLANTATION
Select the 'R' number beside the most appropriate term
2_: r3
Then display the full document; data in CVOC is free. This will
display all the information about the term, showing broader,
narrower and related terms, scope notes, etc. By viewing the full
document(s) you will be able to see whether the term itself is the
most appropriate, or one of the other terms referred to in the
record is better.
