Two quick comments:
One – Interesting that one of kids books (When the Hurricane Came) is a self published work. What does it mean? Not sure. It is not earth shattering news but worthy of attention. I did have a client win a National Jewish Book Award a number of years ago and I was shocked (the book was very good, but was far from confident a self published book would be considered). I was sure they were going to call me and say a mistake had been made.
Two – It seems so logical that the Koren Talmud would win something. How could it not?
