FRAME
Directories relate to a specific subject
They provide short descriptions of websites.
They are a good place to start a general search.
Directories survey what is available on a broad topic.
Examples:
Indexes contain millions of web pages. No one index covers all the web.
Start here when your search is specific or well-defined.
Every word on the sites page is stored in an index.
Examples:
Databases are good sources for answering specific questions.
Most require a password to access the information.
School databases contain quality information that need no formal evaluation
These credible sources provide MLA citations for a works cited page.
Examples:
Searches multiple sources. They are a quick & easy way to expand your search.
Groups together search results like a table of contents
They work best for specific multi word searches.
Examples:
-Search ToolsPrepared by S. Crowther
-Choosing the best Internet resource tool to find the information you need
This allows you to find rather obscure information, but also makes it harder to get good results for many searches.
Sends your search words to many different search tools and brings back one set of results.
What’s Important to understand…
“If you want to drive a nail into a piece of wood, you reach for a hammer, rather than a screwdriver. Use the right tool, and you'll get the right results. The same is true with search engines ... Like a Swiss Army Knife, general purpose search engines often can do many different jobs. Nevertheless, your results might be better if you turn to a subject specific tool.”
