Early in the 1976 growing season the National Weather
Service (NWS) and USDA Extension Service jointly ex-
plored the needs for better localized weather information
to farmers for day-to-day decision making. The result
was AGWX or Green Thumb, a system which provides
farmers with the latest localized weather, agricultural,
market, and other information at a low cost to help them
make better day-to-day decisions.
The key is the Green Thumb Box, which will connect
to the antenna terminals of the home television re-
ceiver and the telephone line, turning the television
receiver into a computer terminal. To access the dis-
semination system, the farmer will call his county Ex-
tension agent's office and be connected to a small
computer. He will then choose up to eight screensfull
of information. The information will then be loaded at
highspeed into a memory in his Green Thumb Box,
the telephone connection will be terminated and the
farmer can view the infonpation at his leisure. If he
wants more information, he will call the county computer
again. The county computer, which feeds the user's
Green Thumb Box, can be readily updated by the county
Extension staff according to local needs. It will also be
updated on a dial-up basis by the state computer with
state and national information. The state computer is
loaded by the state Extension staff, the state National
Weather Service Forecast Office, and on a dial-up basis
by a computer at the National Meteorological Center near
Washington, D.C. This national computer provides
current radar and certain weather information.
Changing weather conditions can be relayed to the
country's 3,150 counties and 2.5 million farmers when
they are in the field or on the road. "Everything in agri-
culture is controlled by weather," Howard F. Lehnert, Jr.,
of USDA's Extension Service, points out. Weather drives
biological mechanisms and is one of the most important
variables faced by farmers. Understanding weather and

its effect on the biological systems within agriculture
opens up possibilities for greater breakthroughs in
controlling pests and optimizing the current radar
and certain weather information.
Initial experience in problems of information gathering
and development was gained in a pilot project in
Maryland. Working with volunteers, many of whom
were "weather hobbyists," data was collected on amount
and type of precipitation, maximum and minimum
temperatures over the past 24 hours, temperature and
weather conditions at time of observation, estimated
wind direction and velocity, snowfall and snowpack,
and in some cases maximum and minimum soil tempera-
tures. The success of the pilot project brought in
other states and information is now received also from
Connecticut, New York, Virginia, North Carolina,
Florida, Ohio, Michigan, Wisconsin, Illinois, Kansas,
The AGWX system was developed to disseminate
collected information. Simulation tests have been run
in various parts of the county. The system will be
tested in October 1979 in two counties in Kentucky
as a joint effort of the National Weather Service,
USDA's Science and Education Administration -
Extension, and the Kentucky Extension Service. This
dissemination benefits farmers by providing information
formerly not readily available. In this way, farmers
can constantly adjust their operations according to
changing needs. (Continued on page 2)

The AGWX system can be a valuable tool for the
private sector that sells specialized information
tailored to an individual farmer's needs. Information
on the system could be further refined and then put
on a commercial parallel system that could be
accessed by a subscriber using his Green Thumb Box.
AWARDS TO BE PRESENTED

MAKING ANIMAL HEALTH INFORMATION EASIER
TO GET: Representatives of the world's major re-
positories of information on animal health and disease
met in Washington, D.C., on December 4-6, 1978, to
inform each other exactly what each of them has collected,
how the information that is being kept can be obtained,
and to offer their opinions about improvements in getting
vital data to those who need it. The International
Symposium on Animal Health and Disease Data Banks
was sponsored by USDA' s Animal and Plant Health
Inspection Service (APHIS) and the Science and Educa-
tion Administration (SEA).
Dr. Edwin I. Pilchard, APHIS staff veterinarian and
chair person of the Symposium, points out that in
agriculture many special purpose information centers
have been developed, primarily to meet the needs of
the sponsoring group or agency. The Symposium was
designed to increase communication and cooperation
among information centers so that more knowledge
can be applied to increasing the needed supply of food
and fiber of animal origin.
The Symposium brought together more than 130 specialists
in such areas as: (1) bibliographic information; (2)
epidemiological information; (3) laboratory and clinical
data; (4) information on research in progress; and, (5)
animal production and economic data.
A directory of animal health and disease data banks-to
be completed from mail questionnaires-is a followup
project of the Symposium. Published proceedings will
include papers that were presented at the Symposium
plus selected papers that could not be presented in

AGRICULTURAL COMMODITIES INDEX: Jane B.
McPall, senior assistant librarian (Life Sciences), The
Pennsylvania State University Libraries, is the editor
of a unique reference work, an index to the United
States Department of Agriculture statistical publications
in series for commodity, input, or product data
appearing in the last decade. Agricultural Commodities
Index, published by Oryx Press, provides ready access
to a substantial portion of historical data and indicates
which series will likely contain supportive current data:
The detailed analysis of the information enables the
user to locate a specific commodity or product, to
identify major inputs and other data elements, and to
determine the broadly statistical and geographic coverage
of the publication. It is intended for any person be-
ginning a data search in the fields of food and agriculture.
Consumers, field workers in agriculture, researchers and
other personnel in the a eas of agri-business, marketing,
food and agricultural economics, will find this index an
invaluable, time-saving reference. The card index which
forms the basis of this work was described in Agricultural
Libraries Information Notes July/Aug., 1977, vol. 3
no. 7/8, page 17. C
U.S.D.A. REGIONAL DOCUMENT DELIVERY
The 1978 report points up some interesting facts.
Requests received were up 4.5% as contrasted with a 1%
increase the previous year. The completion rate fell 1.6%
below 1977 to 73.4%. Costs per transaction went down
.29e based on items received (or .31 on items completed).
Technical Information Systems (TIS) spent an average
of $700 less a month than in 1977.
These trends seem clear:
Volumes sent (rather than photocopies) as a
percentage of all completions is up slightly, as in
Photocopied pages per transaction continue to
climb, largely as a result of regionals supplying
extra copies of CALS (Current Awareness
Literature Service) forms when mailed to TIS.
The principle of verification only on items where the
prospect of error or mis-citation is great seems to
be paying off without dramatic effect on fulfill-
Several very active land-grant libraries in the system
show a major reduction in requests received.
The five regional libraries continue to provide a
greater share of all completions.
