The project was developed in partnership between the Max Weber Network Eastern Europe (MWN Eastern Europe) and the Institute of Russian History of the Russian Academy of Sciences (IRI RAN, Moscow). Further partners were the Central State Archive of Public Associations and Ukrainians (CDAGOU) in Kyiv and the National Archive of the Republic of Belarus (NARB) in Minsk. The project is headed by Prof. Jochen Hellbeck (Rutgers University, USA). Further project leaders are Dr. Viktoria Naumenko (Kharkiv) and Darya Lotareva (Moscow). The technical realization of the digital edition is carried out via the portal for sources and editions QED within the digital publishing platform perspectivia.net of the Max Weber Foundation.
