Search engines: Computer programs that use electronic search programs called spiders, crawlers and robots to collect information sources. Search engines are especially helpful when searching for a focused topic with more than one keyword or phrase. Each search engine has a different way of arranging the results according to relevance and sponsored result lists. Sponsored links are websites that pays to be part of the more relevance results in a search Iist. The user should be careful with those sponsored links while looks for good information.

Metasearch engines: They gather and combine the results of search engines. They are useful for giving a broad picture of what is available on the Web but do not offer as much precision as search engines. As the search engines, metasearch engines arranges the results according to relevance and sponsored result lists. Example: Vivisimo, Ixquick.3. Subject directories: They offer links to subject areas selected and maintained by experts. They should be used when a searcher is starting with a general topic but can provide fewer results and may not be as up-to-date as search engines. The information used to be credible, because it is wrote by experts in the subjects. Example: Librarians’ Index to Internet.4. Subject portals or gateways: They are catalogs of selected content and annotated links to web sites that can be used to find information about specific topic. Example: SearchEric.
Information on the invisible Web accessed through the use of the following searchtools: 1. Subscription databases: They are Web-based services purchased by schools and libraries that offer premium content, which is inaccessible by standard search engines. They can provide full-text magazines, newspaper, broadcast transcripts and reference content. Some popular subscriptions databases include the Online Public Access Catalog (OPAC), which is used for locating library materials; GaleNet, which can be used for research on literary criticism, opposing viewpoints, and biographies; and SIRS Discoverer, which can be used for newspaper, magazine and government document searches. 2. Free databases: They offer free access to their archives, but students must register with a username and password. Example: Library of Congress and the New York Times.Vocabulary: 1. database: Organized and searchable collections of materials that have been filtered and evaluated by publishers, editors and authors. 2. Internet: A large international communication network that links millions of individuals and computer networks electronically. 3. query: A formal information request that is used with search tools to locate web sites that match an information need. 4. relevance: This term refers to how closely a site matches search criteria. Some search engines use special technologies to move the most relevant sites to the top of the result list. 5. World Wide Web (WWW, the Web): A global collection of information on the Internet that can be read and interacted with by a computer.
