Codex Germaniae diplomaticus, worinnen viele vortreffliche ... höchstnöthige Documenta enthalten sind: welche ... weder in dem Teutschen Reichs-Archiv, hoch dessen Continuationen und Spicilegiis zu befinden ... sind, etc. [|].

The Codex Germaniae diplomaticus was compiled by the prolific German jurist and archivist Johann Christian Lünig and published in the early 18th century, specifically between 1732 and 1733. Lünig sought to address significant gaps in the existing legal records of the Holy Roman Empire, creating this collection to archive essential diplomatic documents, treaties, and constitutional records that had been omitted from standard Imperial archives and their subsequent supplements.

Lünig designed the work as a scholarly repository to preserve the legislative history of the Germanic states. The collection served as a vital tool for contemporary lawyers and historians, providing access to primary sources that would have otherwise remained scattered or lost. It was received by the academic community of the era as a necessary, if dense, reference work that solidified Lünig's reputation as a tireless collector of political and legal documentation.
