How to Effectively Locate Federal Information
on the WWW:
Using Search Engines and Subject Indexes to Locate
Federal Information
|
With the amount of government information
appearing on the WWW growing at a phenomenal rate it can be very difficult
to find what you are looking for -- even if you know which agency produces
the information. Fortunately, there are many powerful search engines,
subject indexes, and WWW pages designed to assist you in
finding a particular government information resource. These resources vary
significantly in their coverage. The following tutorial is designed to
assist you in effectively using these resources to find what you are looking
for and will help you answer the questions below.
Search Engines:
Search engines allow the user to
enter keywords or phrases that are run against a database created automatically
by spiders and robots. The search engine retrieves information
based on two things: your query and how the search engine gathers the information.
Since all the top Internet search services operate differently you must
use several search engines to do a comprehensive search.
GovBot
The GovBot database has gathered 307,826 web pages from
U.S. Government and Military sites around the country. Contains easy to
use boolean search forms. One of the advantages of using GovBot is that
it knocks out many irrelevant WWW sites since it only searches WWW sites
that have a .gov or .mil domain name.
Alta Vista
Very fast and easy to use. Often at the top of "favorite
search engine" lists. Help files provide assistance in formulating advanced
queries.
Excite
Easy to use search interface. Excellent online help.
Also provides a subject index approach to information.
Subject Indexes:
Subject indexes are hierarchically
organized indexes that allow you to browse through lists of WWW sites by
topic. They are selective lists of WWW sites that require some degree of
human oversight whereas search engines automatically gather information.
Generally, subject indexes are smaller than search engines. Because there
is human oversight subject guides can save the user time by reducing the
amount of irrelevant information.
Infomine
INFOMINE is a database developed by the librarians
at the University of California, Riverside. It is easy to use and currently
contains over 9,500 records covering most academic disciplines with a large
section devoted to government information. It is known globally for its
high quality scholarly and educational collection. Allows searching and
browsing by subject, keyword, or title.
Yahoo
Yahoo is probably the most popular subject index on the
WWW and often the best place to start when looking for information. The
section on government information covers federal, states, local, and international
government sites. Yahoo also has a search feature that is searches only
Yahoo entries.
Pathway
Services
A service provided by the Government Printing Office
that brings together information from federal agencies under broad topical
entries.
WWW Sites -- other great starting points:

This is simply one of the best sites for locating government
information. The information is current, well organized, and easy to retrieve.
A great starting place for beginners and experienced users alike.

for value-added topical guides which identify, describe, and evaluate Internet-based
information resources. The Government & Law category includes guides
on topics pertaining to the ruling of nations, states, and provinces, municipalities
and other political regions.
Search Tips
Regardless whether you are using
a search engine or a subject index the following tips will help you to
better navigate the resources:
-
Identify key search terms to describe what you are looking
for.
-
Consider synonyms, related words, foreign spelling, and plurals.
-
Read the instructions or help files provided by the search
engine or subject index.
-
Modify your search (broaden or narrow) if you don't find
what your looking for.
-
Try other search engines or subject indexes if you are unsuccessful.
