What Makes an Information Source "Good?"
“Good” sources include those that provide complete, current, factual information, and/or credible arguments based on the information creator’s original research, expertise, and/or use of other reliable sources.
Whether a source is a good choice for you depends on your information needs and how you plan to use the source.
Evaluating Sources Using Lateral & Vertical Reading
The SIFT* & PICK approach to evaluating sources helps you select quality sources by practicing:
  Lateral Reading (SIFT): fact-checking by examining other sources and internet fact-checking tools; and
Vertical Reading (PICK): examining the source itself to decide whether it is the best choice for your needs.
*The SIFT method was created by Mike Caulfield under a CC BY 4.0 International License.

							- Professional fact checkers build a list of sources they know they can trust
 
						 
						 | 
						
						Trace claims to the original context
						
							- Identify whether the source is original or re-reporting
 
							- Consider what context might be missing in re-reporting
