You can start by noting the title and author of the story. Then, provide the publication details like the name of the publication, the date of publication, and the page numbers if applicable.
To cite a long story in an assignment, you need to identify the key elements. That means the title, author, publication source, and relevant dates. For example, if it's from a book, you'd list the book title, author's name, publisher, and year of publication. Pay attention to the specific citation format your instructor or institution prefers.
