This annotated bibliography covers scholarship on the history and social influence of new communication technologies. It begins with innovations in timekeeping, the reproduction of visual images, and Johann Gutenberg's invention of printing with movable metal type--developments between the thirteenth and mid-fifteenth centuries that helped to make possible the modern world. The primary focus of this volume, though, is on the nineteenth and twentieth centuries: steam power, photography, the electric telegraph, the phonograph, the telephone, the electric light and the spread of an electrical network, moving pictures, and the wireless. This bibliography currently has approximately 2,600 entries, and initially appears in an electronic format. Works can be accessed via keyword, or through many broad thematic categories. (Updates vary)
