The Voices of the 20th Century Archive and Research Group operates as an independent archive within the Research Documentation Centre. It contains numerous qualitative research materials of great importance for the history of sociology, from the last 60 years. Its constantly expanding collections include research material on the Roma, interviews on the history of the Holocaust, large-scale interviews on the working life of the 1960s, school surveys and children's drawings from the 1970s, social psychology research, etc. The Voices of the 20th Century Archive contains material by researchers such as István Kemény, Ilona Liskó, Ferenc Pataki, Péter Szuhay, Judit H. Sas, etc.

In curating and safeguarding the collections, the archive relies on the technical background and expertise of the Vera and Donald Blinken Open Society Archives (OSA). Technical support in operating and developing the archive's digital interface is provided by the Institute for Computer Science and Control (SZTAKI).
