In order to search effectively for information on the internet, a person should choose the correct search engine, type in a narrow search topic, refine that searched topic by further narrowing its scope, scan the descriptive entry under each website entry carefully, and read the website quickly, looking for the information needed. For example, imagine that information is needed about the climate of the small city of Sydney, Canada. First, choosing the correct search engine can facilitate the search because some search engines such as Hothot, Snap, LookSmart, and Dog Pound specialize in certain areas – and other search engines such as Lycos, Alta Vista, and Infoseek are best for general information. After choosing the search engine, next type is narrowly focused search topic such as “Sydney, Canada”. The computer will then procedure a long list of websites, perhaps as many as 50.000 dealing with this subject. Next, before looking at any of these website, further narrow the search by typing in more specific information such as “climate” or “weather.” This will procedure a more limited list of website, usually less than 500. At this point, begin to scan the websites carefully. For example, a website entitled “Environmental Science Resources” may look initially promising – but closer examination will show it is a course taught at a university in Sydney. Usually, withing the first group of ten website, one website such as http///www.ns.ee.gc.ca/waether will appear, reading this web site carefully, one can find a hourly update and a yearly review of all weather in Sydney, including temperature, humidity, barometric pressure, wind speed, rainfall, and cloud cover as well as other weather details. By following this process of identifying the correct search engine, narrowing the focus appropriately, and scanning and reading the web sites carefully, the computer user can find relevant information quickly and efficiently.
