The Internet is a worldwide network of
connected computers.
This allows the sharing of electronic
information and resources.
The Internet is considered the LARGEST
telecommunications system ever created.
A common set of rules, known as protocols,
allow the transport and viewing of files and
documents found on computers connected to
the Internet.
The World Wide Web is a hypertext-based
system.
Hypertext allows users to click on buttons or
highlighted text using a mouse to go to other
Web pages containing text, sound, pictures,
or video.
The World Wide Web is accessed by the use of
a web browser.
A browser lets you access the WWW and
“browse” the Internet for information.
You use the browser to maneuver through
web pages.
Title Bar: Lists the title of the web page that
you are viewing. There are three buttons to
the right of the title bar which reduce,
maximize, or close the screen.
Content Area: Displays the current web page
that is open on the browser.
Address Field: Shows the URL (Web address)
of the web page that is currently displayed.
Status Indicator: Shows whether or not the
Web page has completely loaded and can be
viewed.
Progress Bar: Indicates how much of the web
page has loaded for viewing.
Status Message Field: Tells you the status of
the web page. Indicates when the web page is
done and open for viewing.
Scroll Bar: This is used to move up or down
on the web page.
A browser “reads” the WWW pages, which are
written in Hypertext Markup Language
(HTML), and converts them into a readable
form.
To look at an example of HTML, click the
VIEW menu at the top of a browser screen.
This brings down a sub-menu screen. Click
on SOURCE. After viewing, click on X (the
close screen button) to close the source box.
This is part of the Sullivan University Library
home page in HTML.

A web site is a collection of web pages.
A home page is “the front cover” that tells
what is inside.
A web page is an individual page that can be
found on a web site.
http://library.sullivan.edu is an example of a
web address (also known as a Uniform
Resource Locator or URL)
Every web page must have an unique web
address to be found on the Internet.
Your browser uses the web address (URL) to
find information located on another computer
and to retrieve the corresponding page
situated on that server.
Each part of the URL directs the browser to
the correct web page.

Some of the different types of search tools
include:
◦ Search engines
◦ Web directories
◦ Metasearch engines
Search engines include Google, Bing, and
Ask.com
Search engines are used to retrieve specific
websites based on search criteria.
No single search tool finds every website.
Different ones search different and
overlapping parts of the web.
You may get thousands (or millions) of
results, especially searching for a common or
broad term. Some of the results may not be
exactly what you are looking for.
Web directories are a collection of websites
gathered by the creators of the directory or
submitted by publishers of websites.
The websites in a directory are classified by
subject.
Web directories are often useful for
researching broad subjects or topics.
Yahoo! has an example of a web directory.
Metasearch engines are very similar to search
engines but present results from more than
one search engine at a time.
MetaCrawler is an example of a metasearch
engine.
As mentioned earlier, you will not find every
single website on a topic using search
engines.
There is an Invisible Web (also known as the
Hidden Web) that contains websites not found
using typical search engines. Some of these
web sites are found using specialized web
databases.
Ask yourself:
◦ Are there unique words, abbreviations, acronyms or
synonyms for your topic?
◦ Are there any organizations or societies on the web
related to your topic?
◦ Do any of the topic words belong together as a phrase?
◦ Are there any words that you would like to leave out of a
search?
◦ What broader or narrower terms are related to your
topic?
Read the help or instruction pages for the
search tool you are using.
Avoid using words such as “a,” “of,” and “for.”
These are often ignored during a search.
Enter the most important words first.
Often search engines will search and rank the
first term used before any of the other search
words.
Use capitalization for proper nouns and
acronyms.
Use the lower case for words other than
proper nouns. (Many search tools will search
for both capitalized and uncapitalized words
if the lower case is used).
Enclose phrases in quotes: (example: “United
States”) to keep the words next to each other.
Check for mistakes in the spelling of your
search words.
Use Boolean operators (or plus or minus signs
depending on the search tool) to combine
words.
Change the search using synonyms.
Use broader or narrower terms.
Use another search tool.
The Boolean operators are AND, OR, and
NOT.
Boolean operators also called logical
operators) can be used to help broaden or
narrow your search.
The Boolean Operator AND helps you to
narrow a search.
Using AND between two search words
specifies that both of the words must be
found in the resulting websites.
AND “connects” the words in your search.
Say your search is: TATTOOS AND INFECTION
The green shaded area would be your results.
This area includes all the sites that contain
the both the words tattoos AND infection.
The OR operator B R O A D E N S your search.
Using OR specifies that the sites found must
contain at least one of your keywords.
It does not have to contain both of the
keywords.
If your search is PEPSI OR COCA-COLA
The blue shaded area would be your results,
includes all of the sites that contain the
words Pepsi or Coca-Cola, either separately
or together.
NOT excludes terms from a search.
Using NOT between two search words
indicates that you are looking for the first
word but not the second word.
If you are looking for information on
desserts, but don’t want information about
pies, your search would be: desserts NOT
pies
Your results would be in the yellow-shaded
area only.
Netiquette is the proper use of etiquette and
courtesy on the WWW.
Web pages can be updated, redesigned, or
removed
Not everything can be found on the web
Not everything is free on the web
The web may not be the best place to start
your research. You may choose to:
◦ Review encyclopedias and reference books for
background information.
◦ Look at periodical or magazine articles related to
the subject.
◦ Then… look for WWW sites to supplement or update
your information.
Anyone can publish on the web. The author
of a web page may be opinionated or
incorrect about facts.
It is very important to evaluate a web site to
make sure that it contains accurate and
reliable information.
Look at the main purpose of the website.
◦ Is the site informative or does it try to persuade you
of something?
Is the web site accurate?
◦ Are there errors in spelling or punctuation?
◦ Does the information appear reliable?
Look at the authority of the web site.
◦ For example, if the site was published
anonymously, there is a possibility that this may not
be a reliable site.
Look at the point of view.
◦ Does the web site appear to have a bias?
◦ Many web sites are sponsored by companies or
groups that have an interest in promoting a certain
viewpoint.
What is the Currency?
◦ Is there a date on the web site?
◦
◦ How old is the web site?
◦ Has it been updated?
◦ Are the links current?
