Always evaluate your sources for their credibility, truthfulness, and usefulness.
Accuracy. Ask yourself: Does the site misstate or misrepresent facts? Does the site contain errors?
Authority. Ask: Is there evidence the authors know what they’re talking about?
Bias. Ask: Does the site hide the fact they have a point of view or a goal?
Coverage. Ask: How much information is provided?
Currency. Ask: How important is the date to the type of information or field?
Do not use sites that fail your evaluation. Use other, better sites instead.
