Rated 5 out of 5 stars

I work with books, that means searching libraries and data bases all around the world. Before I came across this marveolous add on, I had to chose from my Bookmarks the url of my next search destiny. Now no more.
I admit it is a bit tricky, for a man of letters like me to get the grasp of how to make the thing work, but once you realize that you have to create the engine first, and then the service, it is absolutely easy. All my students will be using it next term.
This is a great application, and I hope the author will keep on adding more features to this really useful application.
