I have not read a single Junie B. Jones book. I know!
But, I am well aware of the dispute about Junie B.; the grammar, the misbehaviour, what kind of role model is she? All I have to say about that is, if every character in kids books were good all the time, it'd be pretty boring.
Anyway, The New York Times examines Junie B. in Is Junie B. Jones Talking Trash? I think the NYT does a pretty good job; because they talked to people on all sides of the issue (pro, con, and librarian), including Elizabeth Bird (sadly, the NYT does not identify her as Fuse) and the brilliant Jill Ratzan, a PhD student at Rutgers SCILS.
