Church and Civil Records from Polish Archives

The National Digital Archives (NAC) has just launched the new online-platform (“Szukaj w archiwach”, poln. “Search in Archives”).
It provides metasearch for finding aids of Polish State Archives like SEZAM, IZA, PRADZIAD, ELA and additionally gives  successively access to scans of church and civil records.
Because of the heterogeneity of sources It is advisable to try different search strategies, f.e. various spellings, current and historical forms of place names, whith and whithout special characters  (“Schneidemühl”, “Schneidemuhl”, “Piła”, “Pila”).
