You've all searched for web sites with search engines like Google before, but don't just take the first few results! Take the time to evaluate each site.
Some web sites are more authoritative than others, such as government sites (.gov). Others, such as those ending with .org, .com, or .net need to be used with care.
Limit Google results to specific domains such as government sites by adding site:.gov to a search.
There are also some ways of adding precision to a web search, e.g., put phrases in quotes (""). For more help with Google, see the Google Search Tips guide.
