The collection contains the entire documentary legacy passed directly from the composer and many other documents added thereto consistently even after Janáček´s death. It is exceptional in its integrity and, with isolated exceptions, it contains all manuscripts of his compositions, copies of his compositions authenticated by him and galley proofs with his revision notes, his manuscripts of librettos, literary and scientific studies, his notebooks and the library with numerous volumes of fiction and scientific literature with his handwritten comments. The collection of Janáček´s received correspondence, later supplemented also by items of sent correspondence, is of particular importance. This collection of manuscripts represents the core of the nomination.
