3. Where do you go for
information?
You are asked to write a
paper on the topic of your
choice and you need
information for your topic.
Where is the first place you
look? Why?
4. Search engines access a
relatively small part of the
web, know as the “free web”
A large portion of the web,
inaccessible to the search
engines, is known as the
“invisible web”
5. What’s not on the free web?
•Around 90% of the books on our
library’s shelves, still under the
protection of copyright
•The full-text of many magazine and
newspaper articles
•Expensive reference books, like literary
criticism, in-depth biographical and
historical works
6. What’s the big deal?...
Your teachers expect quality!
•Material from the subscription services
is likely to be viewed by your teachers as
more authoritative
•You may have to defend some of the
sources you find on the free Web
•You may want to dig deep on the free
Web for some harder to find sources.
7. Prove it!
For example:
Say you are looking for photographs of
the Battle of Gettysburg
You may find some good ones through an
image search on your favorite search
engine
BUT… did you know there is a database
DEVOTED to Civil War photographs?
8. Why?
Search engines cannot pick up those photos
of Gettysburg in that rich database because
the database content is not searchable
until you are actually in the database.

databases too!

10. A brief look at the visible web…

Five Criteria for Evaluating Web Pages
11. A question is not a query
Topic:
Ayurveda-The Science of Healthy Living
Can you create an effective “one-two
word” search?
13. How to structure a good query
1. Brainstorm several key words and phrases
2. Consider alternate forms of words: adolescent,
adolescents, adolescence
3. Be on the look out for better words and phrases
as you search
4. Check your spelling. Bad spelling usually turns
up bad hits
5. Use lowercase letter unless you are searching
for proper names. Turn off the CAPS LOCK!
26. G.A.L.I.L.E.O
GALILEO stands for GeorgiA LIbrary LEarning

1. Name the “virtual library” that Savannah Tech uses that
allows students to access journal articles they would
otherwise have to pay for.
2. What are the benefits of using library resources over
web resources?
3. What source can I use to read books electronically when
they are not available inside the library?
4. Identify three online resources where you can find
information.
