A very comprehensive beginner's guide to Austrian-Jewish genealogy by E. Randol Schoenberg is at www.jewishgen.org/BohMor/ausguide.

Most of the record books ('Matriken') of Jewish births, marriages and deaths in Vienna from the early 1800's to 1938 have survived and are owned by:

The Jewish Community of Vienna.
Israelitische Kultusgemeinde Wien
Matrikelamt
Seitenstettengasse 4
A-1010 Vienna, Austria
Email: h.weiss@ikg-wien.at
Web site: www.ikg-wien.at

Duplicate versions of the Viennese Jewish Matriken have been microfilmed and are in the:

Wiener Stadt-und Landesarchiv
Magistrat der Stadt Wien
Magistratsabteilung 8
Wiener Stadt-und Landesarchiv
Rathaus, 1082 Wien

For civil marriage records (from 1870), birth records (from 1868) and death records (from 1872) of persons who did not belong to a religious community (including many mixed marriages and their children), contact:
