 Some German cities like Munich still do not accept the setting of "Stolpersteine", and look for alternative ways of commemoration instead.Research about future "Stolperstein" locations is usually done by local school children and their teachers, victims' relatives, or local history organizations.The database of Yad Vashem in Jerusalem and the online database version of the 1939 Germany Minority Census are used to search for names and residential addresses of Nazi victims.
