Writing in the shadow of Nazi occupation, the possibility of conforming his work on the Jewish question to certain formal standards of scholarship simply did not exist for the author. In making the English translation of his work, considerable time and effort were devoted to locating and identifying Leon’s source material and quotations, so as to eliminate, insofar as possible, this purely technical shortcoming. We were not always successful in this research project, and it has considerably delayed the appearance of the work in English, but it is hoped that even this limited success will prove helpful to serious students of Jewish history and the Jewish question.
One further word as regards quoted material: English sources have in all cases been used as they appear in English editions – they are not retranslations from the French text. In all other cases, we have utilized standard English translations of foreign works, where they exist; and where the sources remain untranslated we have checked Leon’s text against the original French, German, or Yiddish editions.
