Ogłoszenia zamieszczane w prasie warszawskiej (w latach 1729–1773) jako źródło informacji o bogatej ofercie wydawniczej literatury religijnej

The majority of advertisements published in Warsaw newspapers and magazines in the years 1729–1773, which presented book publishing offers of the Jesuits and the Piarists, referred to religious books. There are mostly sermons, prayers and meditations. The advertisements, both long and short, always inform the reader about the subject of a given book (also the ones which include only a book’s title). Additionally, they give the name of the author or the translator, a publishing house and some information on where a book can be purchased. They are an excellent source of information regarding the need for religious literature. Frequently, they are the only evidence of books which have not survived until today. The also inform about the way in which books were published at that time, e.g. font or paper type.
