British Library, MS Harley 6949 was one among the three newly discovered manuscripts by Jeanne Shami. Its contents have not been edited, and Potter and Simpson were not aware of its existence. The manuscript is a gathering of several separates. Exactly when the parts were brought together in one binding is unknown. Each sermon in the collection is written by a different scribe. Sermons 2, 3, 4, and 5 display evidence of the correcting hand(s) of a later reader(s), who may have supplied readings gleaned from printed folios of the sermons. For two sermons, H1 provides the first and only manuscript witness: OESJD Vol. II.8, on John 11.35, and OESJD Vol. XI.2, on 1 Thess. 5.16, and the manuscript is thus particularly valuable for establishing copy text.
For a detailed description of the manuscript, as well as extensive discussion of the textual value of each individual sermon against other witnesses, see Jeanne Shami, 'New Manuscript Texts of Sermons by John Donne', English Manuscript Studies, 13 (2007), pp. 77-119.
