Albania, Bulgaria, Greece, Romania, and Yugoslavia, with same format for each: General Reference, Descriptive Work, The Land, The People, History ( including Middle Ages), The State, The Economy, The Society, and Intellectual and Cultural Life: with 50 authors, a consultant and three assistant editors. 3,018 bibliographic entries systematically enumerated. Scholarly. Good on slavic translations and both ancient and modern Greek. An example of an area study overview publication, but dated to the late 1960s, funded by US Dept. Health, Education, and Welfare and administered by the American Council of Learned Societies. 112 page index was overdone from an initial document of 640 pages. Chapter 30 is an example of excessive condensing as all Greek history sources was summarized in 16 pages!
