In the mid-twentieth century a new device came into common use, enabling every Tom, Dick and Harry to record and play back sounds stored on magnetic tape. Arriving some 500 years after Gutenberg, the tape-recorder nevertheless had a small part to play in the preparation of text for print. A handful of enterprising writers began using it to record interviews with people whose opinions were (they judged) of interest to the reading public. The recordings were then edited, arranged in a palatable order, and published in book form. These interviews were more detailed and accurate than anything previously thought possible, except by the most tempestuous exponents of shorthand. However, critics of the new approach soon emerged. Were the books worth having? they asked. Was this ‘art’? Was it indeed proper authorship? And if so, who were the authors: those who spoke into the tape-recorders, or those who switched them on?
