Search Bureau for Missing Relatives (or Relatives Search Department;Hebrew: המדור לחיפוש קרובים) was a department in the Jewish agency that was active between 1945 - 2002 with the purpose of helping Holocaust atrocities' survivors locate lost relatives and acquaintances.
During the years the Bureau operated it recorded more than a million inquiries. The Bureau kept a record of these inquiries, and in the 1990s computerized these records. After the Bureau was closed, the database of these records, from the 1940s to the 1970s, was transferred to the Central Zionist Archives.
The Bureau's activities expanded over the years to include also search for missing relatives even not as a result of the Holocaust. For example, the Bureau acted during the mass Aliyah to Israel of the 90s, to trace in Israel the relatives of Jews in the former Soviet Union.
The inquiries of the missing relatives' seekers were filed into folders, and included data regarding the Applicant (usually name, address, date of birth, country of origin) and concerning the people it should locate. If there were any communications regarding the application or any attached documents, it was also filed into the folder along with the original application.
Inquiries portfolios were saved in the archives of the Jewish Agency. These portfolios are not open for public viewing, however, one can contact the Central Zionist Archives for information from the database of records and from the Bureau's portfolios.
Relatives Search requests were published in the media in Israel and abroad. At the beginning, in Mandatory Palestine, these search requests were broadcast by Kol Yerushalayim (The Voice of Jerusalem) that later turned into Kol Yisrael (The Voice of Israel) after the establishment of the state of Israel. Abroad, these requests were broadcast by Kol Zion La Golah ("The Voice of Zion to the Diaspora"), a radio especially established to Broadcast from Israel to the Jewish diaspora. These broadcastings were both in Hebrew and Yiddish in order to reach the widest audience possible. Yael Ben-Yehuda, one of the announcers of "Search Bureau for Missing Relatives" program at Kol Yisrael radio, said in 2006 that for many years she avoided participating in advertisements for German companies after participating in this program.
