Children's literature has transcended linguistic and cultural borders since books and magazines for young readers were first produced, with popular books translated throughout the world. Emer O'Sullivan traces the history of comparative children's literature studies, from the enthusiastic internationalism of the post-war period - which set out from the idea of a supra-national world republic of childhood - to modern comparative criticism. Drawing on the scholarship and children's literature of many cultures and languages, she outlines the constituent areas that structure the field, including contact and transfer studies, intertextuality studies, intermediality studies and image studies. In doing so, she provides the first comprehensive overview of this exciting new research area. Comparative Children's Literature also links the fields of narratology and translation studies, to develop an original and highly valuable communicative model of translation.
