p. 78 "The cultural data of phonograph records was importantly a matter of representation....In many respects it was their physical quality as standardized, mass-produced goods taht helped to enforce their quality as specific cultural data, even as the culture they representd proved variable and unspecific in the extreme....What I am suggesting is that phonograph records frequently proved transgressive of the very cultural categories that they helped to represent as distinct or specific."
