The János Dobri Collection of the Reformed Congregation of Cluj–Dâmbul Rotund contains materials covering the confessional life and activity of the eponymous pastor, which alongside proofs of his individual stand and sacrifice, in the course of the official and private correspondence with the Romanian authorities and private individuals, and beyond the struggle for survival of the Reformed church, also provides an insight into the details of the fight for minority and human rights in the twentieth century.
The József Gyönyör collection represents the work of a lawyer and publicist from the time of his work in the Slovak government (beginning in 1969) at the Department of Nationalities. His main task in the government was to promote the Nationalities Bill of 1968, which aimed to establish a committee of nationalities and partial cultural autonomy. This collection therefore gives significant insight into the efforts of cultural minorities to obtain greater recognition. As a publicist, Gyönyör wrote articles for the Új szó newspaper. In his articles he analysed the situation of the Hungarian minority in Czechoslovakia and Slovakia, and these articles are important as first-hand accounts of status of the Hungarian minority.
