Yordan Hadzhikonstantinov was in touch with the Society of the Serbian Letters (Serbian Academy of Sciences and Arts) in Belgrade and he published some of his discoveries on the pages of Glasnik (an official tribune of the society). On 24 January 1854 Yordan sent from Skopje a manuscript copy of а medieval Bulgarian record, called "A narration about the restoration of the Bulgarian Patriarchate in 1235", which was discovered at first by Dzhinot and was published in Glasnik in 1855. Yordan Hadzhikonstantinov-Dzhinot found a manuscript of a Bulgarian medieval story "An oration of Saint Cyril, how he baptized the Bulgarian people", called "Solunska legenda" ("A legend from Thesalonika"). It was published in Glasnik in 1856.
