That was fun, searching all the nominees and award winners. There are so many of them! I kind of got lost in the Retail section for a bit, but I recovered myself. The big find for me was an air fare locator through http://www.msn.com/. It is accessible on their website by clicking Air Tickets/Travel, and is called Farecaster. I really liked how it works and passed the site on to my kids.
As for Library use, I think there are various sites worth looking at. Some, we already have explored.
