Volume 13 of the series "Ethnographic Problems of Folk Culture" offers eight studies on various issues in the field of historical ethnology, traditional culture, and contemporary ethnology. Three of the texts in the collection are in the field of historical-ethnological research. They provide an anthropological analysis of the history of ideas about Bulgarian ethnogenesis and their connection to political and geopolitical projects, the process of settlement of Bulgarians from Western Thrace in Kardzhali with an emphasis on the "view from below," and the village of Kiselevo as a key haidouk location in northwestern Bulgaria. Three other studies in the collection are devoted to specific issues in the field of contemporary ethnology. They analyze the relationships that are created between people and institutions in Kalofer in attempts to preserve lace-making, a significant part of the local cultural heritage, They examine the processes of counter-urbanization among people of working age and their involvement in rural entrepreneurship, as well as the process of integrating children from foster families into educational institutions in Bulgaria. Two of the texts in the collection are devoted to the traditional culture of communities from the historical Bulgarian diaspora. They analyze the summer cycle of calendar customs among Bulgarian immigrants in Romania—both Catholic and Orthodox—and also provide a comprehensive introduction to the issues surrounding wedding rituals and marriage among Bulgarians in Ukraine and Moldova.
