So what is so different? Well, when you use ScienceRoll Medical Search you do still get results from PubMed mixed in. That is also true of Google Scholar. ScienceRoll, though, is a bit like a blogroll -- "who are your favorites?" ScienceRoll searches the crème de la crème of the medical web -- World Health Organization, Centers for Disease Control, National Institutes of Health, Health On the Net, and many more. Then it gives you what it finds (a little, not too much, some consumer, some clinical) with more suggestions and ideas for refining your search. For a site targeting the general public I can definitely see why Chris felt this was a better choice than dumping John Q Public directly into the heart of the clinical dialog.

PolyMeta is a relatively new metacrawler that searches for websites, news, images, video, and blogs on the major search engines. I was able to add PolyMeta to the search engines in my IE 7 browser, so I’ve been using it a fair amount recently. It’s finicky on occasion, but I like it a lot.
