- Who sponsors or publishes the source? What evidence demonstrates that the sponsor or publisher is credible? What purpose or perspective does the sponsor seem to promote?
- How recently was the information posted or modified? Could it be outdated or obsolete?
- How do you know that the information itself is trustworthy? Are there links to other sites or sources to support factual claims?
