So Many Sources-2

The problem isn't finding sources. There's so much information available. So many possible sources. 

The problem is how to tell when a source is credible.

Understanding credibility is fundamentally important to conducting research. If you rely on the wrong source, your project will be compromised. Also, many teachers ask that you write analysis of your sources in an annotated bibliography or abstract. If your source isn't credible, it will be obvious to your teacher.
