The TVOC Vocabulary file gives you access to the database of
controlled descriptor terms used by the TULSA Petroleum
Abstracts databases of oil and gas-related literature - TULS and
TUSL.
Typical of a thesaurus, TVOC 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.
TVOC is an invaluable aid to searching the Petroleum Abstracts
databases.
