These are freely available databases (although may require payment for fulltext), but as we mentioned at our meetings this month, the typical search engines don't search these specialized deep databases. You won't find Medline results in a Google search. You could search each of the sites DeepDyve mentions on its Expert Sources page but it would mean searching each site/publication individually, so this is a productivity/efficiency tool at least. Currently the focus is on patents, life sciences, and physical sciences. And Wikipedia. More industries to come.
You have to sign up and sign in to use the free version of DeepDyve. Premium version--which offers more complicated display and filtering of results, along with some organizing tools--is $45 per month per user.

Deepdyve's concept is great. The deep web is a gold mine of information we web users can utilize. The only thing that's holding me back from really,really appreciating them is this register-first-before-search thing. I find it so annoying. Other new search engines like http://find.com (which has become one of my favorites) didn't ask for my email add when i first used them.
