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.

Stop
Check your emotional state before engaging.
Do you know and trust the author, publisher, publication, or website?
If not, use the following fact-checking strategies before reading, sharing, or using the source in your research.
Investigate the source
Don't focus on the source itself for now.
Instead, read laterally: learn about the source's author, publisher, publication, website, etc., from other sources.
Find better coverage
Focus on the information, rather than getting attached to a particular source
If you can't determine whether a source is reliable, trade up for a higher quality source
Trace claims to the original context
Identify whether the source is original or re-reporting
Consider what context might be missing in re-reporting
Go upstream to the original source. Was the version you saw complete and accurate?
Purpose
Determine the type of source (book, article, website, social media post, etc.)
Why and how it was created? How it was reviewed before publication?
Determine the genre of the source (factual reporting, opinion, ad, satire, etc.)
Consider whether the type and genre are appropriate for your information needs
Information Relevance
Consider how well the content of the source addresses your specific information needs
Is it directly related to your topic?
How does it help you explore a research interest or develop an argument?
Creation date
Determine when the source was first published or posted
Is the information in the source (including cited references) up-to-date?
Consider whether newer sources are available that would add important information
Knowledge building
Consider how this source relates to the body of knowledge on the topic
Does it echo other experts’ contributions? Challenge them in important ways?
Does this source contribute something new to the conversation?
Consider what perspectives are missing or excluded from the conversation
Does this source represent an important missing perspective on the topic?
Are other sources available that better include those perspectives?
