From Greek antiquity to the present, from the book to the gramophone, from Gutenberg to Google, our culture is defined by changes in recording, storage, and transmission media. In a six-volume selection of his writings, Peter Weibel presents an encyclopedia that addresses all areas of the media world. The author has conceived this series as following in the tradition of the Enlightenment and the Encyclopédie by Denis Diderot and Jean Baptiste le Rond d’Alembert. Three volumes will be published in September 2014, and the remaining three in spring 2015. Volume one deals with a broad definition of architecture in the context of new media. Volume two is devoted to media-relat­ed innovations in the area of music—from automatic methods of composition in the music of Mozart to a theory of molecular music. Volume three addresses the impact of new media on art and discusses how pictures become interactive and viewers become part of the work—how reality replaces representation. The themes of the other three volumes are literature, pol­itics, and theory in the context of new media.PETER WEIBEL (1944–2023) is an internationally known media and conceptual artist, curator, and art and media theoretician. Since the 1960s his work has firmly regarded artistic creativity as an open-ended field of activity. He was head of the ZKM, Karlsru
