You
must evaluate everything you use for your research. However,
if you plan to use information you found on the Internet,
you will need to be even more vigilant in determining its
reliability.
Traditional
print publications are evaluated by the publisher and often
reviewed by the author's peers, while Web sites can be created
by almost anyone and posted without any verification.
In general, Web pages are less reliable than print publications
or articles retrieved from an online database such as Academic
Search.
