This article lists notable open letters that were initiated by scientists or other academics or have a substantial share of academic signees.
Open letters that are not open for signing by other academics or the public in general and have not received both a large number of signatures – in specific no less than 10 before 2000 and no less than 40 after 2010 – and substantial media attention are not included, nor are petitions. With the advent of the Internet and World Wide Web, such open letters may have become far more frequent.
Open letters targeting or defending individual academics or small groups of scholars[1] [2] as well as letters calling for retractions of specific studies are not included.
