ABSTRACT
Finally, another invention that derives from sound cinema and that will prove useful in the service of the cultural revolution is the so-called 'talking book' released in America. On both sides of a special disc about 40 cm. in diameter the
complete contents of a book of up to 350 pages are recorded and can be 'read' to an audience using special equipment . . . Does not this too afford a tempting prospect? . . . The length of this short article does not permit a comprehensive response to this vitally important question but we think that even the brief 'observations' outlined above are enough to ensure that you understand our basic idea:
Sound cinema must be a powerful instrument in the battle for the cultural revolution.
