Yahoo! just introduced a new gadget for searching (better than anything Google or Microsoft have yet produced).  Just like you can in the Research Databases, Search Pad BETA lets you put the search results you like in a notebook, allowing you to organize your research.  It will also save your searches and allow you to add notes.

All you have to do is click on the result (it is added as you go to the website) or drag the result to the Search Pad bar on the (upper) right of the screen.  If you have a Yahoo! account you can also save, email & share your research and notes.
