Finding Credible Web Sources: Evaluating Web Sources

This guide provides tools for evaluating the information you find on the free internet, links to suggested resources for finding credible web sources, and links to citation guides for internet sources.

Spotting Fake News

Infographic from IFLA on How To Spot Fake News: Consider the Source (Click away from the story to investigate the site, its mission and its contact info). Read Beyond (Headlines can be outrageous in an effort to get clicks. What's the whole story?). Check the Author (Do a quick search on the author. Are they credible? Are they real?). Supporting Sources? (Click on those links. Determine if the info given actually supports the story.). Check the Date (Reposting old news stories doesn't mean they're relevant to current events.). Is It a Joke? (If it's too outlandish, it might be satire. Research the site and author to be sure.). Check Your Biases (Consider if your own beliefs could affect your judgement.). Ask the Experts (Ask a librarian, or consult a fact-checking site.).

Strategies for Evaluating Sources

SIFT & PICK

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:

yellow arrow pointing to the right  Lateral Reading (SIFT): fact-checking by examining other sources and internet fact-checking tools; and

green arrow pointing downVertical Reading (PICK): examining the source itself to decide whether it is the best choice for your needs.

Stop

  • Check your emotions 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, such as Wikipedia

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
  • 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
  • Go “upstream” to the original source
    • Was the version you saw accurate and complete?

PICK

PICK

Purpose / Genre / Type

  • 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 / Usefulness

  • 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? Does it challenge them in important ways?
    • Does this source contribute something new to the conversation?
  • Consider what voices or perspectives are missing or excluded from the conversation
    • Does this source represent an important missing voice or perspective on the topic?
    • Are other sources available that better include those voices or perspectives?
  • How does this source help you to build and share your own knowledge?
