Very comprehensive site that has many useful features, including daily podcast booktalks. I often suggest the site to teachers looking for books of a particular genre, theme, etc. Some of her pages that link to this are now wikis.
I've been on Richie's email list for years (and I've even met him), but never thought to look for a single place that holds all of his reviews. He writes some of the most complete reviews I know of, always connecting the books to other events, songs, or materials. I'm often jealous when he writes reviews for great books months before they are released.
