Professor Nagareda died at his home on Friday. In my research on the Google Books case, I had occasion to read many of his papers on class actions. He wrote with elegance, clarity, warmth, and a penetrating intelligence; his book is the best analysis of class-action settlements I have ever seen. I had looked forward to discussing the Google Books case with him someday. That conversation is now just one of many that the rest of us will never have with him. Farewell.
