There isn't a checklist that determines if information is credible, trustworthy, or even appropriate for your research. Start with asking questions to determine how well a source fits your needs. Remember that the information needs to be situated in the context of your research question.
Reminder: Always review the assignment for any source requirements.
How will you use this source in your research assignment?
What value does this source add to your research assignment?
Does the information relate to your research question and/or answer some aspect of it?
