Just One More Book is a thrice-weekly podcast about children's books. The site has book reviews and interviews with authors and illustrators. The group that produces these shows has been at it for a while and has amassed a library of over 100 reviews. You can even record your own review online and send it to the site's organizers. This is a very useful site that is put together with a lot of style and intelligence.
