PRELIMINARY
1. UNPUBLISHED SOURCES.

The amount of important unpublished documents on the Reformation, though still large, is much smaller than that of printed sources, and the value of these manuscripts is less than that of those which have been published. It is no purpose of this bibliography to furnish a guide to archives.

Though the quantity of unpublished material that I have used has been small, it has proved unexpectedly rich. In order to avoid repetition in each following chapter, I will here summarize manuscript material used (most of it for the first time), which is either still unpublished or is in course of publication by myself. See Luther's Correspondence, transl. and ed. by Preserved Smith and C. M. Jacobs, 1913 ff; English Historical Review, July 1919; Scottish Historical Review, Jan. 1919; Harvard Theological Review, April 1919; The N. Y. Nation, various dates 1919.

From the Bodleian Library, I have secured a copy of an unpublished letter and other fragments of Luther, press mark, Montagu d. 20, fol. 225, and Auct. Z. ii, 2.

From the British Museum I have had diplomatic correspondence of Robert Barnes, Cotton MSS., Vitellius B XXI, foil. 120 ff.; a letter of Albinianus Tretius to Luther, Add. MS. 19, 959, fol. 4b ff; and a portion of John Foxe's Collection of Letters and Papers, Harleian MS 419, fol. 125.
