open letter

letter that is not addressed to a specific individual

An open letter is a letter that is intended to be read by a wide audience, or a letter intended for an individual, but that is nonetheless widely distributed intentionally.Open letters usually take the form of a letter addressed to an individual but provided to the public through newspapers and other media, such as a letter to the editor or blog. Especially common are critical open letters addressed to political leaders. Letters patent are another form of open letter in which a legal document is both mailed to a person by the government, and publicized so that all are made aware of it. Open letters can also be addressed directly to a group rather than any individual.
