The following resources have been selected to aid your search of the Internet. There are many tools available and deciding which one to use depends on what kind of information you are looking for. Subject trees are good for exploring a wide range of Internet resources on a particular subject when you do not have a specific site in mind.
Subject trees are more selective than search engines.
You will probably find fewer, but more relevant, links by searching the subject lists in a subject tree rather typing the same subject into a search engine. Some subject trees have search engines that can search for words or phrases within the subject categories. Web Search Engines - Search engines search large parts of the World Wide Web for specific words or phrases. Each search engine will retrieve different results because search engines cover varying numbers of sites and use different search mechanisms. Search engines are especially useful if you are looking for a specific site and know a few key words that might appear in the title or text, or are searching for a very specific subject.
