The Foreign Croatica Collection is the largest collection of books and periodicals published by Croatian authors in foreign countries. The Collection includes publications in many languages covering numerous issues on Croatia and the Croatian people, including those related to the socialist period. It is the most important collection in Croatia containing books by Croatian émigrés banned during the time of socialist Yugoslavia.

The role of the document was to preserve the memory of all persecuted priests of the Diocese of Ljubljana in the post-war period, both those who were killed and those who were imprisoned. The very fact that it was compiled was a challenge to the authorities. The document was maintained in secrecy and it served as a memorial to the bishop and subsequently to the public about the extent of persecution. Today it is a valuable monument to the circumstances when it was created and to its creator. It is located in the Anton Vovk collection in box 74 and it is freely accessible. 

The collection of the D-fund of Prohibited Literature (1945-1991) is located in the National and University Library in Ljubljana and forms an integral part of the Slovenian Press Collection Outside of the Republic of Slovenia. The D-fund mostly contains books and periodicals published outside of socialist Yugoslavia and those primarily pertaining to the Slovenian émigré scene. However, a smaller part of the same fund encompasses the émigré literature of other Yugoslav peoples. In this sense, the D-fund also belongs to the culture of dissent.

The collection of the Slovenian State Security Administration's (UDB-a) surveillance materials about Maks Samec illustrates the mechanism and extent of control exercised by the UDB-a against a Slovenian scientist (chemist) of the older generation (Maks Samec). After 1945, Samec was perceived as an irreplaceable scientist, but also politically suspect, even a potential political and ideological adversary, so he was placed under surveillance.

The collection contains the personal papers of the émigré writer Vinko Nikolić and the archives of the literary quarterly Croatian Review, which the communist authorities banned in Croatia in 1945. Nikolić re-established the review in Argentina in 1951 and was its editor-in-chief until 1990. Additionally, the collection contains the archives of the Library of the Croatian Review, a publishing house founded by Nikolić in 1957. This rich collection is essential for researching the transnational network of post-war Croatian political émigrés, whose literary works were strictly prohibited and labelled as "hostile propaganda" in socialist Yugoslavia.

Four girls (I. K., B. K., Z. P. and D. M.) were accused of printing and distributing leaflets with a poem, which inappropriately (ironically) spoke about Josip Broz Tito and for distributing the so-called Pastoral letter of 20  September 1945 written by bishops of Yugoslavia in September 1945. Bishops strongly disapproved of the actions against the Church and priests (including killing) implemented by the new government. A short poem was entitled “ A Poem for Tito” and was parodying a famous partisan song “Comrade Tito, white violet/, the entire youth follows you” and was beginning “Comrade Tito, blue violet/, your head will be off until spring” asking for Tito’s death. It was signed by “anti-bolsheviks”, and Tito was named as a “Russian bear” alluding to his Soviet connections with Stalin. At this time, Tito’s life and work had still not been protected from contestations, but this example of everyday opposition proved the anti-revolutionary and anti-communist activities, which were related to the inheritance of traditions of the collaborationist Independent State of Croatia, and as such was strictly punishable.

The document was created by the public prosecutor in Zagreb on 28^th December 1945  (No K-3886/45). Iljko Karaman took the document illegally from the Public Prosecutor's office and stored it in his home collection. The material is available for researching and for copying.

Heiti Talvik, citizen's name Heiti Talviken (1904–1947), was a famous Estonian poet who was mostly active in the interwar period. He was 40 years old when he was arrested in 1945 by the Soviet authorities. He was accused of being a ‘socially undesirable element', and sentenced to five years' deportation to the Tyumen oblast. He did not survive, and died of starvation and exhaustion in 1947. Nevertheless, Talvik was not forgotten, and later became an iconic literary figure. His legacy was kept by his colleagues and friends. In 1966, many writers from the Estonian Writers Union requested his rehabilitation, after which it was possible to publish his poems posthumously. A collection of his poems was later published in 1968. The case of Heiti Talvik is important not only as an example of the persecution of cultural figures, but it also shows that such people were often still appreciated by their colleagues, who did not hesitate to restore the dignity of a victim of the repressive regime. 

Control of the cultural life in Latvia was one of functions of the Latvian Communist Party (LCP) Central Committee (CC). The collection of documents furnishes rich information about the formulation and implementation of LCP CC cultural policy, about ‘deviations’ from the official path committed by the cultural opposition, and about attempts to use Latvian culture for the political ends of the Soviet regime in 1940-1991.

The manuscript of Sruoga’s novel Dievų miškas (The Forest of the Gods), written in 1945, is an especially valuable document. The Soviet authorities called the novel worthless, and even dangerous to the regime. The manuscript was heavily censored. It has remarks made by the censor, and the writer’s responses, objections and refutations. Sruoga was heavily criticised for his creativity and his inventiveness, and for his independent stance. This stance was unacceptable to the censors and to the regime. In the end, the publication of the novel was banned. (The novel was only published in Soviet Lithuania in 1957.)
