In 2011, Jean and I both presented at the Children's Literature Association (ChLA) Conference, "Revolt, Rebellion, Protest: Change and Insurrection in Children’s Literature," held at Hollins University in Roanoke, Virginia.
Julia Mickenberg and Philip Nel, co-editors of
the anthology Tales for Little Rebels: A Collection of Radical Children's
Literature, delivered the Francelia Butler Lecture there which was recorded and available for you to watch (it is just over an hour long). It is interesting, funny and very informative and reviews a wide range of literature on the theme: “Radical Children’s Literature Now!” It gives you the chance to see the kind of lectures we hear at academic conferences and is a great introduction to studying children's literature.
The bibliography of the books they discuss is also available, here: http://www.philnel.com/2011/06/25/rcln/
