Different databases enable you to find out on your own, whether the IfZ archives hold materials on your particular research topic before your visit.
The archives' database contains information on records of the following groups of holdings: eyewitness reports, personal papers, documents from associations, collections, manuscripts, court records, state and party documents, maps, posters, and materials on the subject of the IfZ itself. Further information on the individual archival categories can be found here.
The OMGUS holdings (microfiche copies) of the IfZ archives are accounted for by the OMGUS-database
