By analysing literary works, correspondence, and other materials of the members of the secret political organization Cyril and Methodius Brotherhood, it became evident that the members were acquainted with the literary and scholarly works of Ján Kollár, Pavol Jozef Šafárik, Václav Hanka, and Ľudovít Štúr. Thanks to the use of biographical and, to a lesser extent, bibliographical methods, it was possible to make several clarifications concerning the familiarity of the members of the Brotherhood with a given publication – in particular with one of the books that V. Hanka sent to M. Hulak. The article clarified a circle of people from whom the members of the organisation could get information about Slovak and Czech personalities. The studied material constitutes a reliable factual basis for the further reconstruction of the echo of the views of Slovak and Czech leaders in the ideology of the Brotherhood. It is proved that the members of the Brotherhood were familiar – among others – with J. Kollár’s treatise O literárnej vzájomnosti [On literary reciprocity] or P. J. Šafárik’s works in Russian translations. There was also active interaction with the literary heritage of J. Kollár and V. Hanka that influenced the work of Mykola Kostomarov.
