The following bibliography includes major books devoted explicitly to media ethics. They are arranged chronologically. After a productive 1920s and early 1930s, no book on journalism or broadcasting ethics appears again until 1963; this 30-year interruption reflects the influence of positivism on the journalism enterprise. More than half of all the entries have emerged since 1980. While contemporary books are not much more sophisticated than those of the 1920s, this compilation indicates it is presently a highly productive time for media ethics.
