The cemetery of Karolewo had been part of the EZR Płock, 87/88: (Ewidencja Zabytków Ruchomych) documentation.
Maciek Barciński visited the cemetery in 2005 and started the newer documentation. It seems the cemetery did not change too much since A. Pasieka took pictures of the cemetery in 1984.
There is also some historic information about this cemetery.
The cemetery of Karolewo has been part of the documentation EZR Płock (Ewidencja Zabytków Ruchomych Cmentarz Płock) of 1987. The documentation shows the status of the graves and the inscriptions as of 1984.
