Speaking of libraries, I also swung by the San Francisco Public Library and took a quick break from research to look up Olaf in the card catalogue. All copies are out! And it appears that several people are waiting to read returned copies (and that more copies are under consideration). I was very happy to see that. I also stumbled on a nice review by the Roger's Memorial Library:
Menger-Anderson is an incredible writer who creates a collection of interconnected stories that are fascinating, hilarious and beautiful.
