The audio-taped interviews, transcripts, and other documents were collected and compiled by the Raoul Wallenberg Project from 1989 to 1992. Transcripts of the survivor interviews and documents from archives in Hungary, Sweden, the United States, and Great Britain were microfilmed for the United States Holocaust Memorial Museum Archives in October 1994. The interviews and films were purchased and received by the United States Holocaust Memorial Museum Archives in November 1994. Administrative records of the Wallenberg project were not a part of the purchase.
