The Human Nature Review
Internet Explorer Search Toolbar
http://human-nature.com/searchbar.html

This invaluable free toolbar allows you to search resources such as PubMed,
Scirus, Encarta, Encyclopedia Britannica and many other sites directly from
your Internet Explorer (v. 5.01 or higher) toolbar. A term can be searched
across multiple databases with a single mouse click, and the toolbar can be
configured to search the sites that you use most often in your work. It is
similar to the Google toolbar but is designed specifically for those involved
in the natural sciences, the social sciences, and philosophy.
