As part of its own book stocks, Comenius Pedagogical Library has prepared an exhibition devoted to spelling books published on the Czech territory since mid-16th century. In a chronological view it shows the development of spelling books, from faith-teaching books to a specialized “joyful children’s book which can talk with the child as a friend”. The part displaying current spellers was put together by the Fraus publishing house, and it shows the process of how a new speller comes into being.
