Prosvjeta’s archival records were turned over to the Croatian State Archives, then the Archive of Croatia, on two occasions: in 1947 (acquisition 2/1947) and the second time shortly after the abolition of Association, on 23 February 1981 (acquisition 2/1981). The records were relinquished for permanent safekeeping, and accessible for use and research as of 1 January 1983, with the right of disposition in accordance with the prescribed disposition dates.

The collection illustrates Zvonimir Kulundžić's intellectual work as a journalist, historian and literary critic who chose to pursue his activity independently outside of the institutions controlled by the socialist government. The Collection includes books, original manuscripts, the author's published articles, his correspondence and polemics, which reflect a critical standpoint toward Croatia’s institutional historiography and literature in the period from the 1950s to the late 1980s.
