The collection of Ladislav Mňačko (1919–1994), a Slovak writer and former prominent Czechoslovak journalist, consists of unique correspondence, manuscripts, prints and clippings which help to describe the life of this significant writer, who after August 1968 was a critic of the communist regime and a representative of Czechoslovak exile literature.

The Institute of National Remembrance – Commission for the Prosecution of Offences against the Polish Nation (IPN) was created under parliament act of 1998 and is a state body authorised to carry out research, educational, archival, investigative, and vetting activities. The head office is located in Warsaw and there are 11 branch offices in larger cities, as well as 7 delegations. The historical scope of Institute’s activities is very ample, as its operations concern the period from 1944 to 1989.  Its tasks include collecting and managing national security services’ documents created between 22 July 1944 and 31 July 1990, as well as investigating Nazi and communist crimes - against Polish nationals or Polish citizens of other nationalities - committed between 8 November 1917 and 31 July 1990. Other important activities include scientific research and public education. Institute of National Remembrance collaborates closely with State Archives, veteran organisations, historical associations and foreign agendas involved in research and commemoration of the recent history, in particular history of Central-Eastern Europe. 

The Professor of Modern German Literature, Frank Hörnigk from Berlin, published a book with volumes of material about Heiner Müller, already in 1989. In 1998, he began working with the Suhrkamp publishing house to publish a complete edition of Heiner Müller's poems, prose, plays and talks. From the beginning, Hörnigk worked with Müller's estate at the Academy of Arts and later also with the Heiner Müller Archive / Transitraum. After Hörnigk's death (2016), the head of collection of the Heiner-Müller Archive / Transitraum, Kristin Schulz, continued this work. The audiobook she created has 36 hours of audio recording from Heiner Müller, between 1972 and 1995, and received the German Audio Book Prize 2012 in the category “Beste Information” [Best Information].

Congratulations to President Vaclav Havel from Ivana and Pavel Tigrid, sent to him by fax on 5 October 1998, at 2:52pm. Pavel Tigrid and Václav Havel held a long-standing friendship that began in the spring of 1968 when Havel returned from the United States. They scheduled a short meeting in the transit area at Orly Airport in Paris, which then stretched into a whole week that Havel spent at the Tigrid House in Héricy near Paris. In this case, the encounter happened to be when pilots and air dispatchers went on strike at the airport. Tigrid even met Havel and his wife Olga briefly in 1969 when they visited him on his trip to France. After that, Václav Havel was deprived of his passport for a long time, about twenty years, leaving only telephone and written contact between Tigrid and Havel. And it was Havel, who invited Pavel Tigrid to Prague in December 1989 for his inauguration. Tigrid returned to his homeland after over forty years away to help build a democratic state.

The collection contains a great variety of documents that belonged to the historian and politician Sándor Varga. The majority of these documents are from the time when Varga was secretary of CSEMADOK (1968-1970), and they provide unique insight into the activities of this organisation. The collection also contains some documents that are related to the Hungarian youth organisation in Czechoslovakia. This organisation was an important platform for allowing young Hungarians in the country to make their voices heard. Through it, they organised workshops, discussions about the problems of the Hungarian minority in Slovakia, and also discussions about the general political situation (including The Prague Spring and the following events). Despite its short existence, CSEMADOK had a crucial role in the youth movement, and this underscores the significance of this collection.
