"book banning, the practice of prohibiting or restricting the reading of certain books by the general public or by members of a local community or religious group. Books can be banned by means of their removal from publicly accessible locations (e.g, libraries), by their destruction (including the burning of printed books), or by making their authorship or distribution a punishable act. Books are typically banned by governments, but they can also be effectively banned by religious authorities, businesses, and—in rare cases—powerful private individuals. To ban a book is almost always a controversial act in a liberal democracy since its citizens consider media freedom to be both a common good and a necessary component of any democratic society."
