World War 1 postal history remains a fertile field for research.  Years ago, I hoped that some day we would have a scholarly treatment of Luxembourg World War 1 postal history.  Now we do!  You shouldn't be without Lars Böttger, Handbuch zur Besetzung von Luxemburg im 1. Weltkrieg 1914-1918 und der alliierten Besetzung (2014).
