If, like me, you weep at the thought of figuring out where a title is in the Redwall or Little House series, you'll for sure want to bookmark the miraculous "Juvenile Series and Sequels" page produced by the Mid-Continent Public Library.
I also really love Good Reads for both kid's books and adult reading ideas. Easily overlooked but also a terrific resource is our database Novelist K-8. Spend some time wandering through these resources and I'm sure you'll discover some reading gems.
