Here are some World Wide Web sites that will help you zero in on the information you need.
Search engines are brokers of information - sites created to help navigate the Net.
They send out software spiders or robots to read Web pages and collect relevant information about them. That information is used to build a database that Net users can sift through when they want to find something but don't have a clue where to find it. At the same time it helps to know how to use them properly. The more specific the request for information, the better the results. The Internet is a moving feast and without feedback on these and other Search Engines this page will soon become dated.
