The 'Voices of the 20th Century Archive and Research Group' (Research Group) started its activity in the spring of 2009 within the framework of the OTKA (Hungarian Scientific Research Fund) research project nr. 77566. The mid-term objective of the Research Group is to preserve the audio (and audiovisual) heritage of Hungarian sociology (i.e. mapping and collecting sociological studies, with a special emphasis on those based on qualitative methods, conducted in the course of the past fifty years). Furthermore, in the long run, the project is committed to digitalize as well as to archive the sources and to provide enhanced access to our collections.
