Search Engines

Below is a listing of some of the more commonly used WWW search tools sorted by type. As the Web evolves, however, these will not remain constant. Some search engines currently fall into both the indexed database and subject directory categories. More engines may choose this approach in the future or as technologies develop, they may take a whole new approach.
