Austro-Hungarian Empire Ortsippenbücher

Town Compilation of Records (Ortssippenbuch or Ortsfamilienbuch )
See class Online Ortsfamilienbücher at Genealogy.net.
 * An Ortssippenbuch (town lineage book) or Ortsfamilienbuch (town family book) generally includes birth, marriage, and death data for all persons found in the local records during a specified time period, compiled into families. If one is available, it can act as an index or guide to finding the original records. However, they may contain errors, so it is best to verify their information in original records.
 * Sources may include the local parish registers, civil registration records, court and land records, and sometimes published material. In the printed book, this information is then arranged in a standardized format, usually alphabetically by surname and chronologically by marriage date.
