JAMA Migraine Information Center is one of several JAMA information centers that provides good overviews of several common clinical problems. These are valuable resources, and the presence of a statement about the objectivity of the editorial board is reassuring. I also like the AMA's statement about advertising in publications: "No product-specific advertising will be permitted in a multimedia product where editorial content is considered to be of direct marketing interest to the financial sponsor." This sort of statement is notably absent from Medscape and webMD.
