The Erfurt Enchiridion hymnals of 1524 are similar to the Achtliederbuch in that their contents were partly reprinted from Wittenberg broadsides, and the sharp division between broadsides and hymnals is not as clearcut as the DKL classification implies.
Thus DKL clearly establishes the importance of this corpus, although anyone researching the early Strassburg melodies will also need to use Christian Meyer's Melodies des eglises protestantes delangue allemande: Catalogue descriptif des sources et edition critique des melodies, volume 1, Les melodi es publiees a Strasbourg (Baden-Baden: Koerner, 1987), one of the critical editions cross-referenced in DKL.
The DKL editors, however, obviously felt that these melodies should appear in a separate subsection.
In the RISM bibliography, which now constitutes Abteilung 1, both RISM and DKL sigla are attached to each source.
Following the number, the three sigla for the source of the melody - GEdK, RISM, and DKL - are given, together with the letter conveying the confessional identity of the source.
