Accuracy: Does the information seem to be accurate? Does the information correspond with or contradict information found in sources known to be reliable? Has the information been peer-reviewed? Is there a reference list available so you can verify the information? Are there any factual errors, statistical flaws, or faulty conclusions?

Current Information: Is the material up to date? If it is from a website, when was it last updated?

Objectivity (Bias): Are all sides of the issue/topic treated fairly? Do you detect any bias? (For instance, is the author connected to any institution or foundation that might be paying him, which could suggest bias?)
