Children's Literature Criticism

I've been doing a lot of prep work for the class I'm teaching this semester, and that means reading a lot of picture books & criticism, neither of which I feel particularly inclined to write about. However, I would like to put in a plug for an older but great collection of essays on children's literature: Celebrating Children's Books by Betsy Hearne & Marilyn Kaye. It is no longer in print, but if you can get your hands on a copy, I recommend you do.
