With so much information overwhelming us, it can be a challenge to recognize the credible and reliable. There are multiple frameworks available for evaluating information sources. Many of them have memorable acronyms like CRAAP or SIFT. While each takes its own approach and names its elements uniquely, all evaluation of information sources boils down to one key question.
