Gologanov became a collaborator of the pan-Slavic ethnographer and folklorist Stjepan Verković and is considered to be the author of the collection "Veda Slovena".
At the request of Verkovic he collected folk songs, fairy tales, legends, etc., interrupting his work as Bulgarian teacher in the village of Krushevo.
This sensational Slavic Veda contained “Bulgarian folk songs of the pre-historical and pre-Christian times, discovered in Thrace and Macedonia”.
In 1891 the Prime Minister Stefan Stambolov, offered Gologanov to move to Sofia and promising him a pension, but he refused.
The Serian influential Greek circles, as well as the leadership of the Serres Monastery "St. Ivan the Forerunner" gives him great honors because he has influence among his compatriots.
