Literature is any collection of written work, but it is also used more narrowly for writings specifically considered to be an art form, especially novels, plays, and poems.^[1] It includes both print and digital writing.^[2] In recent centuries, the definition has expanded to include oral literature, much of which has been transcribed.^[3][4] Literature is a method of recording, preserving, and transmitting knowledge and entertainment. It can also have a social, psychological, spiritual, or political role.
