Chapter 8 Exercise: Comparing Search Engines


Table of Contents for Entire Course

Search engines are the only tool that attempt to index the whole Internet -- and even they can't cover everything. You can become a better searcher by knowing which search engine is best for which kind of search!!



 

Subject directories, such as lii.org (Librarians' Index to the Internet, which you just used) are wonderful places to begin. They cover quality resources, and human beings select and arrange the resources. Great places to browse!

Sometimes, though, you want to launch yourself out there on the Internet and explore totally on your own. They estimate that there are between 7-8 million new Web pages published every day, so no subject directory could possibly keep up. To explore the larger Web, you use a search engine.

A search engine sends out an automated program (called a robot, a spider, or a crawler) that goes around on the Internet and brings back information. When you query a search engine, you then specify words that, if used on Web pages, would indicate that the page is on your topic.

The Internet is gigantic. There is simply no single search tool that searches through all of it. And search engines are updated at different rates.

The Cabrillo College Library has a search engine comparison chart that helps you get an overview of the coverage and the contents of search engines. It also has searching tips. To get to the chart:
