There are a number of ways to search questions like this over Internet.
Sometimes you can find full-text documents, other times you must settle
for a citation.
Here are two easy ways:
1. Through VERONICA
VERONICA is the "gopher of gophers." It allows you to search, using
keywords, through the gophers of the world.
VERONICA can be found on many gopher sites. It is available, for example,
by telneting to: twosocks.ces.ncsu.edu Login as: gopher. Password=ncces93
At the opening menu, either "arrow down" to #8-NETWORK TOOLS then ENTER or
type: 8, then ENTER
On the second menu page you will find several VERONICA locations, plus a
"how to." Access any of the sites in the same way you got to the second
menu page.
A box will appear. You type your search words here. A possible search
strategy would be: agriculture and energy. ("And" increases the
probability that only documents with both subjects represented are retrieved.
("And" functions like the intersection symbol, the inverted U, that some of
you encountered in symbolic logic in college, or set theory in high school
algebra).
A list of "hits" will appear on the screen after the search is completed
Follow the directions on the screen! Press "m" if you want the individual
file to be emailed to you. Make sure you type your email address
correctly.
Press RETURN to reactivate the hits list. If you want to change your
search words, press "u". That command takes you up a screen. Backspace
through the previous text and retype your new key words.
2. WAIS
WAIS is more complicated in that you are given numerous
search sites to choose from, which means you have to guess from the
location title whether your area of interest is included in the database.
(I hope this previous sentence becomes clearer once you get into the system).
To access WAIS, get to the NETWORK TOOLS line, as you did above. On the
second menu page, get into 13-WAIS: SUBJECT SEARCHES...
Scroll through the individual locations using your arrow keys. You can move
through whole pages with the SPACEBAR (page forward) or the - key (page
backward).
I took a stab at "agriculture and energy" at site
#48-APPLIED-SCIENCE-AND-TECHNOLOGY.src The search yielded 24 citations.
Unfortunately, none of the hits I reviewed included full text.
