The digitisation of the collections of the Music Department of the National Library of the CR continued with four printed books; some of the codices were complemented by handwritten additions. Two of the books made accessible are binder’s volumes of voice books of vocal polyphony coming from the 16th century and printed in Germany and Switzerland; the Czech hymnal from 1727 was printed in the Old Town of Prague; and the last printed book was made in London in 1781.
