The “Documents” collection is published in Sofia in the beginning of 1945. The author Nathan Grinberg (1903—1988) is an economist, politician and polyglot, who was appointed by the Fatherland Front at the Commissariat of Jewish Questions after September 9, 1944. The documents he finds and collects in the institution are reproduced in this book. Some of the documents are connected with the deportation of the Jewish population from the “New Bulgarian lands” in Thrace, Macedonia and Pirot.
