"Twelve years later, in 1983, with the total number of diffusion publications grown to almost 4,000, Rogers published the third edition which further revised the theoretical framework and introduced new concepts and theoretical viewpoints. All three editions have extensive bibliographies of works cited and are indexed." (Eleanor Blum, Frances G. Wilhoit: Mass media bibliography. 3rd ed. Urbana: University of Illinois Press, 1990 Nr. 364)
