After 1804, it was published with the supplement Wochenblatt zum Nutzen und Vergnügen, replaced in 1818 by the supplement Illyrisches Blatt, which was then published until 1849.

Illyrisches Blatt was the center of Slovene cultural creativity.

Its contributors were the Slovene national poet France Prešeren and other influential Slovene intellectuals such as Matija Čop, Miha Kastelic, Franc Malavašič, and Janez Bleiweis.

After the establishment of the Slovene-language newspaper Kmetijske in rokodelske novice in 1842, the influence of the Laibacher Zeitung declined because it gradually became the herald of the German-speaking community in the Slovene lands.
