“Textbooks don’t smell as their contents rot, so readers will need to develop alternative crap detectors to avoid
poisoning their minds and robbing their patients of current best care.”

Review
Name three things you should look for in a web site with medical information that would make you feel more confident about the content of that website.
What resources are going to be the most accurate, reliable, and up to date?
Name a library drug reference, a differential diagnosis resource, and a disease quick reference
