As soon as Google Scholar hit the streets there was quite a stir in the library community and various ponderings about how to tie it into existing library systems, so it was inevitable that someone would develop this, but this quickly!!! A Firefox extension which, when you perform a Google Scholar query, also sends queries to your institution’s OpenURL resolver, and in cases where your University owns a licensed copy of the cited article creates a link directly to it. Too cool! – SWL
I have tried Google Scholar. Amazing. It should be in every educator’s bookmark list.
David Mattison also points to a number of other Google Scholar bookmarklets that may be of interest, including this one.
