Overall Search

Expert Search offers separate expert searches for objects, locations and persons.


The object search allows the specific search for an object's originator, title and place of origin and in all metadata. You can also search through all books digitised in full text.

By using the search box "Refine search", search results can be further improved. Also, all search results can be filtered by using the check boxes on the left of the screen.


Here you can search for places, communities, districts, waters, forests and mountains in Bavaria today; also for places, communities and district offices in the Palatinate.

The search for locations is explained separately in bavarikon's location database . Not only official places and municipalities can be searched for, but also administrative districts and geographic areas in Bavaria.


bavarikon's person search facility allows to search specifically for entries in a variety of biographical resources. It is possible to search for surnames, first names and occupations, the latter currently only allowing German-language entries.

Special case : when searching for sovereigns, princes and people from the time before the introduction of fixed surnames, the "first name" has to be filled into the first search box.

Using the search box "Refine search", search results can be further improved. Also, all search results can be filtered by using the check boxes on the left of the screen.
