Name Directories of Berlin Civil Registry Offices

The Landesarchiv Berlin recently provided access to digitized name directories of the Berlin civil registry offices.
The large number of parishes and (since 1874) civil registry offices make family research more difficult in metropolises such as Berlin. If the address of the requested person or family is known or can be identified with the help of the Berlin address books, one can find the responsible office for the corresponding time period.

Digitization makes the research significantly easier and preserves the original documents. An archival visit is not necessary in many cases: if the document number was determined in the directory, a copy can be ordered directly from the archive.

NSDAP membership card index

The digitization of a total of approximately 12.7 million NSDAP membership index cards has now been completed at Bundesarchiv. Since the access is restricted by legislation on protection of privacy, there is little change for the users. Browsing the files in the reading room can now take place optionally on the PC or on microfilm readers. It would be a good idea to tag the single files or link them with geodata in order to reconstruct the regional context lost by the rearrangement of the card index in preparation of the Nuremberg and denazification trials.

The cards of the index contain brief, formalized information such as name, first name, date and place of birth, occupation, membership number, date of application, date of joining the party, termination of membership, address changes, passport photo. The Federal Archive provides information on individual persons on request. A prior clarification of the access authorization is necessary for the use of the inventory on site. The National Archives in College Park (Maryland) have a microfilm copy of the entire material.
