A correction in a newspaper consists of posting a public notice about a typographical error or factual mistake in a previously published article. Newspapers usually have specific policies for readers to report factual errors. Generally, this requires the reader to contact an editor, pointing out the mistake and providing the correct information. Sometimes, an editor or affected reporter will be asked to refer to a note or press release to determine how the mistake was made. In print newspapers, a correction notice will often appear in its own column in a subsequent issue.
