It's too late to go, but today I received email notice of a big conference on cemetery art that's being held in Warsaw today and tomorrow (Dec. 4-5).
It looks as if it is all Polish scholars (and all in Polish), and the topics range over the whole field of graveyard/gravestone studies, both civic and religious, including monumental cemeteries and war cemeteries. One session is devoted to Jewish cemeteries in particular.
