Okay, so Dewey didn't quite save the world but he did change the lives of those he came in contact with, namely Vicki Myron, the head librarian at Spencer Public Library. Even Vicki acknowledges that without Dewey, nobody would even care to read her story which I found equally fascinating and a good reminder that a library is more than a building or its books. It's about the people who work there and active members within their communities. A great read for those who love reading about libraries and about cats.
