Surfing is not
searching.
  “Computers download
     information—

• They do not teach you to think.
• Computer education imparts technical
  skills.
• It does not impart knowledge.
Not all the information that exists in
the world is on the Internet.

Not all the information that is on the
Internet is accurate.
An hour on the Web may
not answer a question that
you could find within two
minutes of picking up a
reference book.
       Getting Started
         Searching
            URL’s
• Uniform Resource Locator (URL) is:
  – the web “address” that connects you
    with a website.
  – goes in the address bar at the top of the
    screen.
  – gives you information about the
    website.
             Parts of a URL
    http://yosemite.epa.gov/oar/globalwar
    ming.nsf/content/index.html
• http://--hypertext transfer protocol:
•   the language computers use to “talk” to one another
• www—world wide web:
•   the body of information connected by the cables and computers of the Internet
•   . yosemite.epa—domain name:
•   the structured, alphabetic-based, unique name for a computer on a network
•   .gov—top     level domain:
•   gives an idea of where the document is stored
•   /globalwarming—file         name:
•   a folder within a website
•   .html—hypertext             markup language:
•   the computer language used to format documents
    Top Level Domains
•   .edu—higher education
•   .k-12—elementary and secondary schools
•   .com—commercial
•   .gov—government agency
•   .mil—military
•   .org—general noncommercial organization
•   .net—computer network
      Who Pays For The
         Internet?
• Advertisers pay for Internet websites.
• Popups and banners are trying to influence your spending
  habits.
• The information on commercial sites--.com—may be
  presented in such a way as to encourage you to buy a
  particular product.
• Be wary of URL’s with a ~ in the address—this indicates
  a personal homepage and does not guarantee accuracy.
  How Do You Find What
       You Need?
• Libraries are organized.
• No one is in charge of organizing the Internet.
• Well-prepared searches will eliminate useless hits
  and wasted time.
Before you search, you
       need to:
• Prepare
• Organize
• Combine
             Prepare
• What do you need to know about your topic?

• Make a list of all the terms connected with
  your topic.

• Include names, organizations, and phrases.
              Organize
•    Make a list of the words that are critical to
    your search.

•   Note terms that you don’t want to see appear.

•   Discard the rest.
For example…
•If you are looking for information about life on the
planet Saturn, you don’t want sites popping up about
the automobile.
•Put that in your list of words you don’t want to
see.
•What other words might be connected with your
topic that will send you to useless sites?
             Combine
Use Boolean operators to combine your most
 important terms.

• Use AND to connect the terms you want to
  see.
• Use NOT to exclude terms you don’t want.
• Use OR to include similar terms.
• Use quotation marks around names or phrases
• Use lower case for all proper nouns, except for
  acronyms
For example…



    saturn AND planet AND life NOT
    automobile NOT car
But what if…

you WERE looking for information
about the automobile? Your
search will look like this….
saturn AND automobile AND car
NOT planet
What Do You Use To
     Search?
• Search engines
• Search directories
• Metasearchers
   Search Engines
• Are like the index in the back
  of a book
• Let you search for specific
  words and topics
• Use robots known as spiders
  to search for information.
           Examples:
•   Google
•   Alta Vista
•   Excite
•   Hotbot
•   Infoseek
Search Directories--
•Are like the table of contents in
front of a book
•Let you search for concepts or
subject categories
• Go from general to specific.
•Sites are added by people.
         Examples:
• Internet Public Library
• Yahoo
• About.com
Instead of looking through the
categories in a search directory,
you can put in your terms in
their search bar, but it will only
look through the sites that have
been included within that
directory—not the entire web,
unless indicated.
  Metasearchers--
• Sends your search terms to
  several other search engines at
  once.
• Gives an overview of a topic
  across the Internet.
        Examples:
• Profusion
• Dogpile
• Metacrawler
      Remember….
• Hits are returned and ranked
  according to--
  – How many times terms appear on
    the page
  – How often terms appear
  – How close terms are to each other
  – How near the top of the page the
    terms are found
      Remember….

• The best results will appear on
  the first page or two of hits
• No two search engines are alike.
  Try another search engine, or
  rephrase your terms if you don’t
  get good results.

Evaluating Websites
     “Let the buyer beware”

•Book publishers weed out
inaccurate information.
•No one checks the Internet for
accuracy.
