The IOS is structured into three divisions – Economics, History, and Library and Electronic Infrastructures (as well as its administration and Directorate). Research is organized in four interdisciplinary research focus areas. It is run by the Foundation for the Study of East and Southeast Europe (Stiftung zur Erforschung von Ost- und Südosteuropa), a foundation under public law. The Foundation’s internal bodies are: the Board of Trustees, the Board of Directors (Directorate) and the Academic Advisory Board. The basic funding is effected through the Free State of Bavaria, represented by the State Ministry of Education and Culture, Science and the Arts; in addition, third-party funds are raised for research projects and for the creation of research infrastructures.
