Subject Directories contain a collection of links to Internet resources submitted by a site creators or evaluators and organized into subject categories. Subject directories are resources recommended by experts.
Examples: Yahoo (www.yahoo.com), About.com (www.about.com)
Search Engines are searchable databases of Internet files collected by a computer program. Use search engines when you are looking for a particular web site, have a specific research question or are looking for current information.
Examples: Google (www.google.com), Lycos (www.lycos.com), Altavista (www.altavista.com)
Meta-search engines send searches to several search engines at once, and then build the results into a coherent results page.
Examples: Dogpile (www.dogpile.com/index.gsp), Metacrawler (www.metacrawler.com/index.html)
Field searching allows you to restrict your search to a particular field within a Web page, which can narrow your results. For example, you want to find Web pages about the Spiderman comics and you suspect that you would get more accurate results by looking only within the title.
Example: Title: Spiderman comics
Wildcard Searching - If you don't want to exclude terms that end with s, ing, etc., use a wildcard search by truncating the search terms with an asterisk (*).
Example: Tex* will get Texas, Texan (be careful, you will also get text, textile, etc.)
Phrase Searching is used to find exact terms, use quotation marks.
Example: "Blue Suede Shoes"
