Diplomataria et scriptores historiae Germanicae medii aevi cum sigillis aeri incisis, opera et studio Christiani Schoettgenii,... et M. Georgii Christophori Kreysigii. Accedit praefatio Christiani Gottlieb Buderi,... de damnis detrimentisque archivorum quorundam Germaniae

Published in Altenburg in 1753, this ambitious collection represents a significant effort by 18th-century German scholars to systematize the study of medieval history. Compiled by Christian Schöttgen and Georg Christoph Kreysig, the work serves as a massive compendium of primary source documents and historical treatises. It reflects the Enlightenment-era passion for archival research, aiming to bridge the gap between fragmented local records and a coherent national narrative for the German lands.

The volumes are particularly notable for their inclusion of high-quality copperplate engravings, which document the seals and iconography of medieval charters and manuscripts. The inclusion of Christian Gottlieb Buder's preface, which mourns the loss of various German archives, highlights the urgent historiographical mission of the time: to preserve historical records before they succumbed to the ravages of war and neglect. The work remains a cornerstone for scholars of diplomatic history and German paleography.
