Excellent Source for German Story Reading
http://germanstories.vcu.edu/ Lots of great 19th century German stories! Includes dual-language pages, glossary/dictionaries, and quizzes. My personal favorites: "Der Stuwwelpeter" and "Max und Mortiz".
Here is a place to get children's story books in many languages. http://www.childrenslibrary.org/icdl/AdvancedSearchCategory?selIds=61&viewIds=3&rnum=1&text=&lang=English&view=cover&sort=title&match=all&location=everywhere&ilang=English
