The site indexes huge chunks of Internet content and delivers the information sorted conveniently into folders. Using many search engines is better than using one search engine. When I research a topic, I let Copernic 2000 look first. It looks for your topic on 10 search engines, discards duplicates and gives you the results on one page. It also lets you search newsgroups and e-mail addresses.
Search engines change constantly.
My favorite newsletter about search engines is ResearchBuzz. If I decide to use a search engine to find, for example, a company's Web site that I can't find in one of my free online company directories, I plug it into Google. I've found I get great results.
