Internet search engines (e.g. Google, AltaVista) help users find web pages on a given subject. The search engines maintain databases of web sites and use programs (often referred to as "spiders" or "robots") to collect information, which is then indexed by the search engine. Similar services are provided by "directories," which maintain ordered lists of websites, e.g. Yahoo!
