The formal, structural, exponential, linguistic and close reading approaches to literary analysis - are they present in Hamletand Huckleberry Finn? What are the differences between those approaches?
These approaches differ greatly from each other. The question isn't whether or not they are present in these stories. It's more a question of whether these approaches would be good for the stories you've mentioned. I've enclosed a great link that has explanations of the different approaches. Close reading isn't really an approach, but rather what you do when you analyze a text. For instance, if you're using a feminist approach to Hamlet, you will read closely for anything that you can find regarding treatment of, reaction to and characteristics of women. That way, your reading is focused and "close." I hope that helps.
