Hello Israel,

Files on the DP camps are kept in the Salzburg State Archives (https://www.salzburg.gv.at/archive).

I myself did research in the files of the DP Camp Parsch. 

Unfortunately, there is no file index for the mentioned stock and the archive boxes are only roughly labelled with keywords or file numbers, which is why even after the boxes in question have been narrowed down, a large number of possibly relevant contents (estimated at about 70 boxes) still remains. In addition to general camp reports, the inventory also includes medical reports, emigrant's files and personal applications for camp supplies.

Kind regards,
Johann Hammer
