The collection is made of auxiliary documentary material about amateur theatre in connection to professional theatre in Slovakia. It is directly linked to information about theatre. It complements the profile of theatre-makers and ensembles, including the major ones: Z – divadlo zo Zelenča (Z – Theatre from Zeleneč, Jozef Bednárik), Študentské divadlo Filozofickej fakulty UPJŠ/PU (Student Theatre of the Faculty of Philosophy, The Pavol Jozef Šafárik University in Prešov, Karol Horák), Divadelné združenie Partizánske (Theatre Association Partizánske, Jozef Krasula), Divadlo Jána Chalupku z Brezna (The Ján Chalupka Theatre of Brezno), etc.. The material within the collection is essentially organised similarly to the other collections: by theatre ensembles, amateur theatre festivals and who-is-who.
