Mark Puterbaugh, Information Systems Librarian (Warner Memorial Library, Eastern University) answered positive to my question if he could see any good use of such a sidebar for consumer health resources. When asked for which resources it should include next to the obvious MedLinePlus, he added MayoClinic, the FDA and PubMed "Primarily it could be used as a reference tool while preparing for research. Students could use this to explore a topic in which they have an interest before hitting the commercial databases. Consumer based resources are excellent tools in which to gather the ideas and terminology that may be unfamiliar."
It took me 5 minutes to create the 4URHealth Sidebar (install page) I used the simple widget feature for all 4 resources. In most cases this simple widget feature works fine, but offers little options to fine-tune results. The 4URHealth Sidebar will offer results from above mentioned resources in a sidebar after search actions in GOOGLE, YAHOO, BING and YOUTUBE,
