Literary classes, also known as GENRES, are categories of literature that are based on the style, form, and content of the work. GENRES can be divided into two main categories: fiction and non-fiction. Fiction includes GENRES such as fantasy, science fiction, horror, romance, and mystery. Non-fiction includes GENRES such as biography, autobiography, history, and journalism. Literary classes are important for readers to understand the type of literature they are reading and to help them find books that they will enjoy.
