Wanka's Post-Handbuch: verfasst nach ämtlichen Quellen aus Anlass der auf dem Weltpost-Congresse zu Wien beschlossenen Aenderungen in den internationalen Post-Vereinbarungen

Published in the late 19th century, Wanka's Post-Handbuch was created by Josef Wanka to serve as a comprehensive reference guide for the complex international postal regulations established during the Universal Postal Union congresses in Vienna. As international mail systems expanded and standardized, practitioners required a centralized resource to navigate the shifting landscape of inter-state postal agreements.

The manual was designed as a technical handbook for post office administrators and logistics professionals. It is recognized for its thorough integration of primary source data and legal texts, reflecting Wanka’s intent to provide clarity in an era of rapidly evolving global communication protocols. It remains a significant primary document for those studying the history of 19th-century bureaucratic systems and the professional standardization of European post.
