Book burning is the deliberate destruction by fire of books or other written materials, usually carried out in a public context. The burning of books represents an element of censorship and usually proceeds from a cultural, religious, or political opposition to the materials in question. Book burning can be an act of contempt for the book's contents or author, intended to draw wider public attention to this opposition, or conceal the information contained in the text from being made public, such as diaries or ledgers. Burning and other methods of destruction are together known as biblioclasm or libricide.
