n The ability to find material quickly and accurately is at the root of the internet experience whether the user is a rookie surfer or a research scientist. The search vehicles we use depend largely on the kind of information we are looking for and, to some degree, on how we like that information to be presented on-screen.

For those who like a simple search giving a huge number of accurate hits, AltaVista is one of the most popular. (It also offers a superb translation service for several European languages.) Of the directories - facilities which link subjects in groups for users who are struggling to think of a key word or words - Yahoo is a world leader. Indeed, recent research showed it to be the most visited site on the Net (ahead of, would you believe it, Pokemon.com).

Then there are the metacrawlers which, unlike search engines, do not actually crawl the web themselves; rather they facilitate simultaneous searches on several engines with the results being blended on to one page.

I particularly like Inference Find (www.infind.com) which taps into AltaVista, Excite,

Infoseek, Lycos, WebCrawler, and Yahoo. Unlike many metacrawlers, it doesn't group results by search engine or in one giant list, but clusters results in subject groups so you can quickly see which documents are relevant and which are irrelevant. If you are interested in search engines, how they work, or how to use them more efficiently, go to Searchenginewatch.com. This site explains and reviews a vast number of search facilities and, for the anoraks among us, offers subscription to a monthly newsletter on search engines which will be fired into your

e-mail inbox.
