Scan the perimeter of the page

• name of page author • organization, institution, agency you recognize • e-mail contact by itself not enough • Credentials for the subject matter ?
– Look for links to: “About us” “Philosophy” “Background” “Biography” • Is it recent or current enough ?
• Look for “last updated” date - usually at bottom • If no links or other clues...
• truncate back the URL http://hs.houstonisd.org/hspva/academic/Science/Thinkquest/gail/text/ethics.html
