Book burning, or tomecide, is the ritual 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.
In some cases, the destroyed works are irreplaceable and their burning constitutes a severe loss to cultural heritage. Examples include the burning of books and burying of scholars under China's Qin Dynasty (213–210 BC), the obliteration of the Library of Baghdad (1258), the destruction of Aztec codices by Itzcoatl (1430s), and the burning of Maya codices on the order of bishop Diego de Landa (1562).
In other cases, such as the Nazi book burnings, other copies of the destroyed books survive, but the instance of book burning becomes emblematic of a harsh and oppressive regime which is seeking to censor or silence an aspect of a nation's culture.
Book burning can be an act of contempt for the book's contents or author, and the act is intended to draw wider public attention to this opinion. Examples include the burning of Wilhelm Reich's books by the FDA and the 2010 Qur'an-burning controversy.
Art destruction is related to book burning, both because it might have similar cultural, religious, or political connotations, and because in various historical cases books and artworks were destroyed at the same time.
In modern times, other forms of media, such as phonograph records, video tapes, and CDs have also been burned, shredded, or crushed.
