The Manga Question

I am having a hard time finding valid sources to judge the Shakespearean mangas I have found. I think I might have to study up on the history and criticism of manga itself in order to be a good judge of the material. I have found a source for manga: Japanese Visual Culture : Explorations in the World of Manga and Anime [0-7656-1601-7] Macwilliams yr:2008. I will read a few chapters of this today and post a list of the characteristics of exceptional manga either tomorrow or on Friday. I will also start reading King Richard III tonight, if I have time.
