I was pointed at this paper by Laura Atkins: What’s the Story?: Reflections on White Privilege in the Publication of Children’s Books. She’s asking for comments on the paper to be posted on her blog: here.
Among other topics she touches on the Justine Larbalestier Liar controversy (by the way, a new cover has now been agreed for this book) and relates this to her own experiences of publishing multi-cultural children’s fiction.
