The collection is among the most specific of the kind. It currently contains nearly 1,300 textual stage adaptations. It consists of directorial, stage managers’ and actors booklets, as well as those designated for dramaturges, prompters and technical personnel. Individual theatre-makers have left in the booklets valuable testimonies about the productions that we no longer have an opportunity to see, and about their era. The collection contains notes from some of the leading theatre-makers such as Ján and Oľga Borodáč, Andrej Bagar, Hana Meličková, Ján Jamnický, Viliam Záborský, Mária Bencíková, Július Pántik, Eva Kristínová, Pavol Haspra, Soňa Valentová, Martin Porubjak and others.
