NPR had an intersting article this morning about peer reviewing at Amazon.com. I got to it from the Podcasts.com website. I found the NPR: Books page. I could listen to the weekly podcasts there and, after reading a few help windows, found out how to subscribe to this in Bloglines. I also searched for children's books and added childrensbookradio to my feeds.
While I tried all of the suggested sources for podcasts listed, I found the first I tried -- Podcasts.com to be the easiest to use to subscribe to the feed in my Bloglines account. They all seemed to be listing the same podcasts.
I added 3 feeds to Bloglines -- NPR:Books, childrensbookradio, and Nancy Pearl book reviews. These or at least snatches of these will become part of my regular listening.
