Lack of systematic quality control means critical evaluation of Web sites is crucial. When evaluating web resources, consider:

• Authority: Is the author or site sponsor clearly identified? Can you find credentials and contact information?
• Objectivity: Is the site's purpose clear? Is it directed toward a specific audience?
• Coverage: Are the topics covered clear? In depth? Balanced? Are ideas and opinions backed up by evidence?
• Accuracy: Are sources cited? Can you verify accuracy of facts and other information with other sources in the field?
• Currency: Are the dates included in the website? Is the information current, or at least still relevant for the site's and your purpose?
