- Consider the source. Are the authors/producers clearly identified? By
what authority do they write? Look for well-known
names in health and medicine.
- Note whether the URL includes.gov(governmental),.edu
(educational),.org(non-profit organization), .net
(network), .com (commercial), or a two-letter code
(country of origin). Governmental and educational sites are generally the
most reliable; organizational sites are often
excellent, but may have a biased agenda; the same
applies for .net and .com sites -- examine with a critical eye.
- Have the authors/producers provided a convenient means to contact them? A
credible source will reply to your questions.
- How current is the information? Look for the "last updated" information on
the main page, but be aware that individual sections
may have different dates.
- Is the main purpose to sell a product or service? Unless the sources of
information are credible and clearly identified, do
not trust the information.
- Are there links to other relevant Web resources? Be wary of sites that do
not point outward.
- Starting with an authoritative source does not mean that progressively
distant links are reliable. If you are unsure where
you have landed, cut off the end of the URL and try
to identify the main source. The symbol (~) can indicate
a personal page.
- When in doubt, DOUBT.
