- Who is the author, publisher, or sponsor?
- What are the author's credentials or organizational affiliations?
- Is the author qualified to write on this topic?
- If no author is listed, is the organization publishing or hosting the information well-known and highly credible on the topic?
*For web sources, also ask yourself... does the url reveal anything about the author or source? (example: .gov or .edu is likely more credible than a .com or .org)
