What is a Metasearch engine?

• A meta-search engine is a search tool that sends user requests to several other search engines and/or databases and then gathers together the results into a single list or displays them according to their source.

What are some good metasearch engines?

Dogpilehttp://www.dogpile.com . Nice because it points to the search engines and also gives tabs for video and images

Excitehttp://www.excite.com Only looks at google, yahoo and bing but also gives tabs like dogpile.

• MetaCrawlerhttp://www.metacrawler.com Seems to favor Yahoo has tabs like dogpile

• Search.comhttp://www.search.com Seems to favor bing

iBoogiehttp://www.iboogie.tv/ Not Commercial relies on Blekko, seems pretty academic

• IxQuickhttp://www.ixquick.com/ No tabs, doesn’t list the search engines.

Be careful!

• We are not here to buy things from the web so steer clear of websites of a commercial nature.

• Some good bets for valid websites depend on sponsors and include those ending in:– .org– .gov– .edu

• Who owns the site? Is it a reputable group or organization?

• Is the information current? • Does the source tell readers where its facts are from?
