TIP:
One way to find a more reliable site is to search for ones created at or by educational institutions. To do this, use the Google Advanced Search option and limit your search by setting domain or site preferences. Enter .edu (U.S.), .edu.au (Australia), .ac.uk (United Kingdom) into the domain/site box and the results retrieved will only be associated with educational institutions. But even here, you will need to validate the information.
