The evaluation tool introduced here is designed to be used with all types of resources. You constantly need to be asking yourself the questions in the evaluation, regardless of the format of the material. We do put more emphasis on evaluating web sources, but each source you are going to use in your work should be evaluated with a critical eye. Don't just take what is written at face value; think about it.
