Lenard Cohen applies the techniques of sociopolitical research and analysis to Yugoslavia's system of government over the entire period since World War II. A massive study, the product of many years' labor, it makes a signal contribution to our knowledge of the makeup of Yugoslavia's "new class" as personnel and personnel policy has changed over the years. Some readers may find the book rather dry, politics seen through an array of statistical tables with little on the colorful personalities, cutthroat rivalries, high ideals and sordid realities that are the stuff of life at the top. But that of course is a different book. The author has done what he set out to do and has done it superbly.
