The collection was further expanded in February 2018 at the occasion of the new release of ZEDHIA version 1.03. 90 volumes of the Wiener Zeitung Official Gazette (Amtsblatt, 1812-1902) were added to the collection on the portal. Combined with the editions of the Central Journal already available (1902-2001), this allows over 190 years of Austrian economic and company history to be researched on ZEDHIA.

In addition, 10 volumes of the Austrian Central Land Cadastre of 1908 containing all trading, industrial and commercial enterprises of a region as well as the Vienna Property Cadastres (1905/1913, 1927-1928) containing land and home owners, street names and orientation numbers as well as information on plots and buildings were added.
