There are multiple factors to consider when evaluating a source's credibility, such as:
For this assignment, we ask you to look specifically at the source type and the author—two factors that contribute to the source's authority. Take a closer look at the authority of the source by using the Markers of Authority below. If you're going to be using these sources for a paper—or if you're ready to take your evaluations further—look at the other factors that impact a source's credibility. You can use the ACT UP method to guide your evaluation.
Ask for help from your librarian at any time!
Markers of Authority
Did you find it through a link on the library's website?
The library acts as a gatekeeper, selecting and making available trustworthy resources.
Does/do the author(s) have credentials in the field of research?
Scientists, researchers and academics who publish their ideas and findings should have appropriate advanced degrees in their field.
Is it peer reviewed?
Research articles that undergo peer review and get published have a marker of authority by design.
What about the post-publication peer review process?
Have other scientists, researchers or academics commented on the work? Are there reviews, commentary or retraction notices?
If a source has been through peer-review, much of the credibility evaluation has already been done for you!

The ACT UP method for evaluating sources was created by Dawn Stahura as a way to critically evaluate information sources in which the user takes an active approach to consuming and producing information.
