In book publishing, an anthology is a collection of literary works chosen by the compiler; it may be a collection of plays, poems, short stories, songs or excerpts by different authors. In genre fiction, the term "anthology" typically categorizes collections of shorter works, such as short stories and short novels, by different authors, each featuring unrelated casts of characters and settings, and usually collected into a single volume for publication. Alternatively, it can also be a collection of selected writings (short stories, poems etc.) by one author.
