Finding Information on the Web
|
|
As the number of web pages grew, people needed a way to access
this information. Search engines were created to fulfill this need
by indexing words on web pages and storing the information in a
searchable database.
One search engine can not possibly index every web page currently
available. Some of the best search engines currently available,
as identified by SearchEngineWatch.com,

Why Use Web Sites for Research? |
|
Web sites can be very useful sources of information. Use Web sites
for
- background information
- current information
- images or multimedia information
- information from special interest groups, associations and
local and national organizations
- international information
- popular information
- statistics
TIP: Be careful when using Web sites for research. You may
come across inaccurate and offensive information because anyone can
publish on the Internet. Some information may appear authoritative
or scholarly, but after critical evaluation
it may be seen as biased, or intended to sell or persuade. You must critically Evaluate each website!

How To Search in Search Engines |
|
When you use a search engine it seems like you are directly
searching the whole Web, but that's not really what happens. You
are really searching a database or index of URL links. You can only
find links to sites that are included in the search engine's index.
These links may have been collected by a program called a "Web
crawler" or by a human evaluator.
Internet search engines are used to find all types of information
and media on the Internet. Search engines provide lists of Web sites.
Each engine searches differently and finds different information.
No search engine will search the entire Internet. Use several engines
if you are doing research.
