The cult of the book in Gdansk manifested itself in the numerous substantial private libraries, marked by the features and qualities of bibliophile facilities, as indicated by the artistic bindings, ex-libris and supralibros of their owners. After their owner’s death, many of the book collections of Gdansk bibliophiles were provided to the municipal library, of which the current Gdansk PAN Library is the heir and continuator. The books have historical bindings, represent a variety of styles and epochs, and many different adornment techniques. The majority of Gdansk patrician families and wealthy burghers belonging to the political, cultural, and scientific elite of the city had coats-of-arms granted to them by the Polish, Danish, or Swedish rulers, or Roman-German emperors. From among many volumes kept in the collection of the Gdansk Library and marked with coat-of-arms supralibros, sample prints from the collections of thirteen representatives of Gdansk bibliophiles were selected.
