Stop

  • Check in with your emotions. The story or headline may be crafted in a way to generate your anger or excitement in order to get you to click links and view ads.
  • Before you read, share, or use the information, first investigate the source’s credibility and objectivity. Make sure that you can trust the author, publisher, publication, or website.
  • If you are unfamiliar with the person or organization providing the information, then go to the next step.

Investigate the source

Navigate away from your information source in order to see what other sources say about the person or organization who is responsible for the information you are evaluating. Here’s how:

  • Look up the author, publisher, publication, or website using a search engine or Wikipedia to find out about them from other sources.
  • Determine the expertise and agenda of the person or organization providing the information.
Search tip

Using a search engine, type wikipedia after the domain name of a site, or after a person’s name, to show the wikipedia article at the top of your search results.

Find a better source

If you have doubts about the quality of claims on the webpage you are viewing, or want to find out whether a certain claim is true or false, use other news sources and fact-checking sites to verify information about the claim.

Use reliable fact-checking sites to verify claims:

Search tip:

Using a search engine, enter the claim you are trying to verify followed by the name of a fact-checking site to see if any articles about the claim appear at the top of your search results.

Search tip:

Enter the claim you are trying to verify in the Google search bar and click the News tab of your search results in order to confirm that other news sites are reporting the same story.

Search tip:

Confirm claims by searching them in large, nationally-known news sources. Free, full-text access to major daily newspapers is available to CCSF students, staff, and faculty through the U.S. Major Dailies database (use your RAM ID), such as:

Trace claims to their original context

  • When verifying a claim or news item, locate the original reporting source for the claim or news. 
  • Phrases such as “According to…” are clues to the original source of information for a story. 
  • Look for quotations from experts and do a web search for their name or for the organization they represent to seek the original source of the claim.

Citing Sources

hand with finger pointing rightAny words, ideas, or images that you do not create or come up with yourself must be properly credited to avoid plagiarism.  

Citing information sources acknowledges the origin of your information, and it provides support and credibility to your work by showing evidence of your research.

A citation is a reference to the source of an idea, information, or image. It typically includes enough identifying information (such as the author, title, date,  publication format, etc.) for someone else to be able to locate it themselves. Access the CCSF Library Citing Sources guidance for information on how to properly credit a source.
