In a vocabulary information system it is important to have a con-
trolled vocabulary for information retrieval. However, when searching
the data base of the National Technical Information Service (NTIS) for
environmental research reports, one is faced with using search keywords
from four thesauri as well as free language terms. These keyword
sources are: The Department of Defense thesaurus, Energy Research and
Development Administration thesaurus, National Aeronautic and Space
Administration thesaurus, the thesaurus used by NTIS, and controlled
free language terms. This microthesaurus integrated hierarchically the
vocabulary of these five sources to allow easier retrieval for environ-
mental terms. Generic relationships and thesaural origins are main-
tained for each term.
The microthesaurus is divided into two sections:
The first section contains more than 1800 terms that
express environmental concepts relating to water, air,
noise, and radiation pollution, disposal of solid waste,
and environmental health.
The second section lists more than 550 chemicals that
are important to environmental studies. Those chemicals
not covered by one of the major thesauri are named using
a modified version of the American Chemical Society
(Chemical Abstracts) nomenclature.

INTRODUCTION
~T~ his Environmental Microthesaurus was prepared by NTIS to assist users of the
' NTIS data base in retrieving environmentally oriented reports. A diversity in ter-
minology exists in our data base because reports announced by NTIS are
catalogued and indexed not only by NTIS, but also by other agencies that use their
own indexing keyword vocabularies. Currently these keywords may be found in
four separate thesauri as well as in free-language terms. The thesauri used are:
• DDC Retrieval and Indexing Terminology (Dept. of Defense).
Availability: NTIS, $30.50, paper copy or $4.50, microfiche (order number, AD/A-001 200-SET).
• ERDA Subject Indexing and Retrieval Thesaurus (Energy Research &
Development Adm.)
Availability: NTIS, $16.25, paper copy or $3, microfiche (order number, TID-7000R1).
• NASA Thesaurus. Volume 1, Alphabetical Listing and Volume 2, Access
Vocabulary (National Aeronautics & Space Adm.)
Availability: NTIS, Vol. 1, $15, paper copy or $3, microfiche (order number, N76-17992)and Vol.
2, $8.50, paper copy or $3, microfiche (order number, N76-17993).
• Thesaurus of Engineering and Scientific Terms (Test) (Dept. of Defense
and Engineers Joint Council)
Availability: Engineers Joint Council, 345 E. 47th Street, New York, NY 10017, $20, soft cover,
$25, hard cover.
This microthesaurus is an attempt to bring together the environmental terms
from these thesauri and to show their heirarchical relationships. Because stan-
dardization of indexing terms is of great utility in retrieving information from data
bases, we hope this microthesaurus of already established terms will aid those
planning to produce an environmental indexing vocabulary, as well as those who
search our data base.
The microthesaurus is divided into two sections:
• The first section contains more than 1800 terms that express environmental
concepts relating to water, air, noise, and radiation pollution, disposal of
solid waste, and environmental health.
• The second section lists more than 550 chemicals that are important to
environmental studies. Those chemicals not covered by one of the major
thesauri are named using a modified version of the American Chemical
Society (Chem Abstracts) nomenclature.
he terms in this microthesaurus are identified by source as follows:
T
(D) DOD Thesaurus (E) ERDA Thesaurus
(N) NASA Thesaurus (T) Test Thesaurus
(*) NTIS free-language terms, not in above lists.
Where keywords are contained in more than one thesaurus, each source letter is
given: eg, (DNT), (DENT), or (ET). Other symbols used in this microthesaurus are:

NT Narrower Term RT Related Term
USE Use what follows SEE UNDER A cross reference
DEF Definition of terms NOTE: Brief explanation
Entries exist for all synonyms, including spacing variations: eg,
Law (Jurisprudence) (N) and Law(Jurisprudence) (DT).
This is the first edition of this microthesaurus of environmental terms; and up-
date is planned for next year. Any comments or suggestions would be most
welcome. Rlease write to Information Analysis Branch, National Technical Informa-
tion Service, 5285 Port Royal Road, Springfield, VA 22161.
