As already mentioned in the Introduction, a vast literature on the German church struggle has already appeared in German, the titles of which, up to 1958, were published in the bibliography by Otto Diehn, Bibliographie zur Geschichte des Kirchenkampfes 1933-45 (Goettingen 1958). Since then much of the vast quantity of governmental and Nazi Party records for the period 1933-45 has become available to scholars, either in the archives of Western Germany or through microfilm collections prepared in Great Britain and the United States. The following bibliography does not attempt to be comprehensive. Only the main works and sources used have been cited, and much of the ephemeral literature which appeared during the period of the Church struggle has been omitted.
