Slovakia Church and Synagogue Books, 1592-1935
When accessing "Slovakia Church and Synagogue Books, 1592-1935, Jewish (Židovská obec), Nitra, Nitra", I've noted that, of the 17 volumes available for searching, the final 6 from "Births (Narodenia) 1871-1872 Marriages (Manželstvá) 1869-1870 Deaths (Úmrtia) 1856-1865, 1867-1868, 1869-1895" to "Index (Zoznam) 1851-1885" cannot be accessed.
The message "Image unavailable - This image is unavailable for online viewing at this time" is displayed. Is this due to a glitch in the system or have these particular volumes been withdrawn for another reason?
I'm carrying out research on Jewish ancestry for this region and would like to search these special volumes.
