As a scholar and a teacher Betty Gilderdale has been a trailblazer for decades. Our foremost expert on New Zealand childrens literature, she's written extensively on the subject for publications the world over. But it is a story of her own, the tale of a little yellow digger, stuck in the mud, that she made up for her grandsons, that's guaranteed her a place in history, and a place in the hearts of generations of young readers.
