WWW subject gateways
Subject gateways are tree-like information retrieval systems.
There is usually a list of a few main topics on the subject gateway
home page. When you click one of the main topics, a new page
with more specific topics appears. Browse the pages this way
until you find the desired information. Most subject gateways can
also be searched with keywords.
The information in subject gateways is selected by subject
experts using specific selection criteria, so the quality of
the information in gateways is higher than in
seach engines which are
maintained automatically. Use subject gateways when your topic is
extensive and not well defined, or if you need an overview of
the information available on the Internet.
