A veteran newspaperman who knows the Soviet scene treats the subject of information and communication from several angles. On the management of information as an instrument of power and control, he gives a standard account. On the efforts of Western media to reach the Soviet public, he writes with welcome candor. He is most interesting, if more speculative, when he writes about the "underground telegraph" by which Soviet citizens inform themselves and each other of facts they do not get from the official media. One well-argued conclusion, portentous for the future, is that in time the technological revolution in communications will make it impossible for the Soviet government to keep the Soviet population insulated from the rest of the world.
