These essays were originally presented at a symposium of the same title that took place at the annual meeting of the American Association of the Advancement of Slavic Studies in Toronto on November 20, 2003. The charge to the participants was to "to reread the book and make short presentations on it, its significance, the validity of its analysis in hindsight, its historical contribution to our understanding of late communism, its influence on others." The symposium was timed to commemorate the thirtieth anniversary of writing of the book in 1973–1974 as well as the twenty-fifth anniversary of its publication in English in 1979.
