Check Everything

Now that you've searched and found various information sources, how well do they all fit together?  Do different sources contradict each other?  How reliable is the information you found?  As you research it is vitally important to critically review and reflect on everything you encounter, even the most seemly reputable sources.

Review the following criteria and answer the questions based on the information you are evaluating. A high quality source with quality information will enable you to answer MOST of the questions with a "YES."
