"The study is based on a critical edition of the travel journal of Slavist Adolf Černý which he wrote during his work in the Czechoslovak delegation at the Paris Peace Conference in 1919, and two sets of private family correspondence from his colleagues (expert advisors from both the Czech and Polish delegations) - Václav Vilém Štech and Kazimierz Nitsch and their wives. Černý's journal from the Paris Peace Conference and Štech's correspondence are stored at the Masaryk Institute and Archives of the CAS in Prague (Masarykův ústav a Archiv AV ČR, v.v.i.). Personal papers of philologist Kazimierz Nitsch are stored at the Archive of Science of Polish Academy of Sciences and Polish Academy of Arts and Sciences in Cracow (Archiwum Nauki Polskiej Akademii Nauk i Polskiej Akademii Umiejętności)."--Page 430.
