Geistliche Lieder zu Wittemberg, Wittenberg: Joseph Klug, 1543.
This is a new edition of Klug’s Wittenberg hymnal, Geistliche Lieder auffs new gebessert zu Wittenberg, first published in 1529 and reprinted in 1533 and 1535. The title page gave the date 1543, as did the colophon at the end of the hymnal. A scan of a nearly identical exemplar, dated 1543 on the title page but with the date 1544 given in the colophon, is available here.
The 1543 Klug hymnal introduced a number of new hymn texts, including several by Luther: Vom Himmel kam der Engel Schar, Was furchst du, Feind Herodes, sehr, Christ unser Herr zum Jordan kam, Erhalt uns Herr bei deinem Wort, and Der du bist drei in Einigkeit.
