To find a short story in Randall Library's catalog, select "author" and enter the name of the short story's author (last name first). Then look for a title that indicates a short story collection. It is difficult to find a short story by title in the catalog because they are usually published in collections and anthologies, but you can also try using quotes around the title of the story.
To search for criticism of a short story within a book, consult Randall Library's catalog, select "subject," and enter the name of the story's author (last name first). Then search for the subject heading subdivision "criticism and interpretation."
