Library Databases vs. Search
Engines -
What's the Difference?
First let's clear
up one big misconception that is:
"All the information in the world is available on the
Internet."
Actually, only a small fraction
of the world of information is available on the Internet. Think of all
the
books
and
magazines that were published before the invention
of computers and networks. Much of the published information out there now
is available only in print. Copyright law is one reason why much information
is not online. Copyright protects authors and publishers from other people
reproducing their work without permission. How would an author or publisher
make money if people could get everything for free on the Internet?
Library Databases vs. Search Engines
- The only similarity between these two resources is that they are both
accessible via the Internet. Now let's take a look at the major differences
between them:

Review Process:
All information contained in library databases comes from publishing groups
and goes through a review process before it is published in electronic
or print format. This means the information has been checked for accuracy
and reliability by the publisher's editors. Students should still evaluate
information found in library databases since there is plenty of published
information that can be inaccurate or biased. It is also important to
determine if the information is relevant or appropriate for your research
topic. For a checklist of evaluation criteria, click

The Internet is not owned or controlled by any one organization or group
which means information or web pages found through search engines DOES
NOT go through a review process. This lack of authority allows anybody
to publish their opinions and ideas on the Internet. While this information
may be interesting, some of it may not be useful for academic research.
Pages may be written by an expert on a topic or a journalist but many
pages may also be written by a disgruntled consumer or sixth grader. In
view of this, web pages found through search engines should be carefully
evaluated for their accuracy and reliability. For a checklist of evaluation

Cost / Accessibility:
Library databases are NOT FREE. The library pays each database service
vendor (company) a yearly fee for access to their databases. GTCC students
may access many of these databases from home or outside the library by using
a username and password provided by the library. To request remote
access to GTCC's library databases, click

Most search engines and web pages found through search engines are FREE.
Search engines will also find links to proprietary web sites or databases
that are not free or do not allow access without a username and password. |
