What to look for when selecting a quality website, blog or wiki:
A. Accuracy. If your page lists the author and institution that published the page and provides a way of contacting him/her
B. Authority. If your page lists the author credentials and its domain is preferred (.edu, .gov, .org, or .net)
C. Objectivity. If your page provides accurate information with limited advertising and it is objective in presenting the information
D. Currency. If your page is current and updated regularly (as stated on the page) and the links (if any) are also up-to-date
E. Coverage. If you can view the information properly
