Tips For Using Search Directories:
Popular search engines such as Google and Yahoo use complex computer programs to index websites, and these enormous indexes can then be searched using keywords. Search engines rank pages depending on how many times a keyword appears on a webpage (relevancy) and where a keyword appears on the page (proximity). Google also uses popularity ranking, taking into account how many times searchers link to a page when using a certain keyword. It’s important to remember that search engines search electronically whereas most search directories use human editors to exclude irrelevant sites and include beneficial ones. Search engines are businesses that rely on ad revenue, so be aware that some sites show up because they have paid for a high ranking not because they have the information you need. Search engines in order of popularity are Google, Yahoo and Ask.com. Microsoft's new search engine Bing is worth a look as well.
It is very easy to edit a Wikipedia article, so many academic teachers do not trust the informationon on this site as editors and authors aren't identified and so the credibility of the information is questionable. In fact Wikipedia does not recommend its informaiton be used for academic research as noted in this entry Reseaching With Wikipedia. Wikipedia articles are good for tracking down sources used by authors however and can be a good place to start research.
