Winston Smith's job is to rewrite history. He works for the Ministry of Truth (Minitrue) and is responsible for propaganda and historical revisionism. "His job is to rewrite past newspaper articles, so that the historical record always supports the party line. A large part of the ministry also actively destroys all documents that have been edited and do not contain the revisions; in this way, no proof exists that the government is lying."
