Thanks to Claire Imholtz for her review of The Place of Lewis Carroll in Children's Literature in Winter 2010 issue of The Knight Letter, which is The Newsletter of the Lewis Carroll Society of North America. She concludes that it's a "most informative, enlightening, and highly recommended book, an important addition to the literature of general Carrollian readers and academics." That was generous of her and I appreciate her thorough review and generally positive notes.
I have been in touch with editors at Routledge, the book's publisher, and may have more positive news about it soon. I'll post more info when it's available.
