You can use German local newspapers to inquire for genealogical help in your ancestor's town. However, you may have a better response if you use a local genealogical society periodical rather than a general newspaper. The following is a current newspaper directory for Germany:
- Benn's Media Directory International. Tonbridge, England: Benn's Business Information Services, annual. (FHL book 011.35 B439.) This is arranged by the nation and city of the newspaper.
Newspapers printed during your ancestor's lifetime may contain birth or marriage notices. Death notices and war casualties are especially common in old German papers. Death notices typically list birth and death dates and burial places. Sometimes they list the birth place or immediate family members. Since few indexes are available, you must know the approximate date of the newspaper to search. Newspapers became more common in Germany after 1855, when a tax on paper was lifted.
The Family History Library has virtually no German newspapers. A few related items may be found in the Locality Search of the catalog under the name of the town or state and the topic NEWSPAPERS. For example, copies of the Augsburgisches Intelligenz-Blatt 1797-1827 and the Intelligenz-Blatt und Wochentlicher Anzeiger von Augsburg 1827-1899can be located in the locality section of the Family History Library under Germany, Bayern, Augsburg - Newspapers. The Amts-Blatt der Koenigl. Bayer. Stadt Augsburg1900-1917 is listed under Germany, Bayern - Newspapers1. To find newspapers in German repositories, use the source below:

German Immigrant Newspapers
In most places where Germans settled around the world, they published a German-interest newspaper.
