A digital catalogue of musical compositions from the 19th–21st century with themes of Hus or the Hussites. Upon closer examination, the compositions can be viewed from varying perspectives. Aside from the purely musical (e.g. form, casting, use of musical quotation), there are also more general criteria such as the nationality of the composer, the occasion for which the composition was produced or to which it reacted, and no less important is the political, religious or social context. "Repertorium" aims to become a digital catalogue with information for example for musical directors, radio editors, musicians, conductors and choirmasters, in general for all those who wish to learn the necessary information either about a specific composition or through filtering come to output of a more summary nature. In contrast to classic catalogues, the individual records can be supplemented with recordings, scores, scans of title pages, etc.
