Google
One of the most powerful search engines in the world. The best starting place to look for detailed information on the Internet.
Yahoo!
The directory that needs no introduction. The most visited site in the world. Very good for specific web research work that is based on keywords and categories.
Virgilio
Italy's first Internet portal. Beyond its own directories, it allows you to use, in an Italian environment, the world's best known search engines.
AltaVista
One of the "classic" search engines. Still a good choice for a "second opinion."
