byFarrar, Straus & Giroux, $10.00; paper $3.95. Mr. Voinovich, creator of the hilarious Private Chonkin, describes his own private troubles in moving to a new apartment in a writers’ cooperative building. The affair proves to be a matter of Byzantine intricacy, but not, unfortunately, at all amusing. It does offer considerable information about the exercise of personal clout ir. the Soviet Union.
