Read Kiddo Read
Readkiddoread.com is a really fantastic new site that is dedicated to getting children excited about reading. The site is well-organized with a wonderful book recommendation section that is broken down by age group. Just browsing through it, I found several books that I'd like to check out for my kids. While I believe the site was mostly intended to be an aid to reluctant readers, I think it'll also serve those parents (like me) who have avid readers that are constantly searching for what to read next.
Along with the book recommendations that are divided into Illustrated Books, Transitional Books, Pageturners, and Advanced Readers, there's also an interview section (there's a great interview with Jeff Kinney, author of Diary of a Wimpy Kid up now), and a forum where you can chat with other parents, teachers, and librarians. I think it'll be a great resource for anyone with an interest in getting children to love reading.
