Why the Library?

 
Why Library Databases?
 
 Library Databases:
  • Are paid for by the Library so that you can have free access to scholarly information.
  • Content is evaluated for authority and accuracy.
  • Information is stable, meaning it doesn't disappear after a period of time.
  • Through subject pages it is easy to find databases with information that relates specifically to your topic
  • Offer options to quickly limit or expand your search results to find the best articles for your topic.

The Internet:

  • Many sources are free, but others require you to pay.
  • Information is not evaluated for accuracy and may be incorrect, misleading or biased.
  • Websites come and go.
  • Is not organized.
  • Search engines (like Google) often return an overwhelming number of results.  These search engines offer no quick way of narrowing your results to ensure they relate to your topic.
