Finding Criticism in Books
One way to find criticism of particular short stories in books is to search for criticism on the author. For example, in the Library's Online catalog, using the subject search, type in Porter, Katherine Anne. What you will find are several options; select Criticism and Interpretation to find those books with criticism of her fiction. Remember, when you look for the books on the shelf, look for other books in the same area that might be useful.
There are reference titles that include criticism or will lead you to critical material.
