Despite concentration on the current Communist era in Bulgaria, important historical factors are referred to as necessary, for more full understanding of the contemporary scene. An historical chapter is also included to provide the proper setting for the modern state. An extensive bibliography and a convenient glossary are provided. (Author/ND)
