The portal is a collection of knowledge on composers, genres, contexts (e.g. letters, indexes of figures associated with a given composer), and broadly understood art from Poland’s partitions period. The website showcases 25 individuals, including Ignacy Feliks Dobrzyński, Franciszek Lessel, Józef Krogulski, Franciszek Mirecki, Maria Szymanowska, Mieczysław Karłowicz, Stanisław Moniuszko and Juliusz Zarębski, featuring biographical notes on all of the composers, complete catalogues of their works, timelines of their life and musical activity, as well as lists of literary references and iconography related to each individual artist. Although the bibliographic section is the most developed part of the website, music resources and filmography are constantly being enhanced (alongside the list of documentary films and contributions from music experts).

The website is a great exploration space for music experts and educators looking for teaching inspirations and materials or to create their own educational resources.
