From 20 to 21 September 2022, research was carried out at the National Archives of Australia in Canberra, with the help of Renata Dyer from the Parliamentary Library in Canberra. Documents related to Croatian newspapers published during and immediately after the Second World War were reviewed. Valuable sources were found, important for research in the field of information science (eg. research on editorial policies and state censorship), but also for research in other fields such as history, political science and sociology. In addition to the documents, some issues of publications that are not available anywhere else were found, and one title was discovered that is not mentioned in the literature nor is it available in library collections.
