The first move when you are considering a source is to Stop and take a beat. What do you already know about this site? What are your goals for your research?
Now, investigate the reputation of the author, publisher, publication, or website from other online sources (not necessarily what they say about themselves).
Search Google News or Google Scholar, or dig into the library's collections through Saint Search. You can use the News scope to narrow down to just news articles if that's what you're looking for.
Identify whether the source is the original or re-reporting. Consider what context might be missing and then see if you can find the original source.
