We can find lots of objects documenting and describing life of our ancestors in collections of libraries in DLF. In case of actual territories of Poland, years ago they were inhabited mainly by Slavic tribes, so as the roots of Polish state are. In the note below, we depict only a smal part of the large amount of publications concerning Slavs, that can be found in Polish digital libraries. First of them, appropriate for the introductory reading, is a slight book Słowianie: ich rozsiedlenie i liczba (eng. Slavs: their settlement and population) from the Podlaska Digital Library. It treats of the grounds resided by Slavs, nations that were included in the tribe and their influences throughout the years. Next publications filling in to the world of Slavic culture are 4 volumes of Dzieje Słowiańszczyzny północno-zachodniej do połowy XIII w. (eng. History of Slavic north-west areas until the half of 13th century) from the Silesian Digital Library and Początki kultury słowiańskiej (eng. The beginnings of Slavic culture) from the Chelm Digital Library. In SDL we can find also a well preserved 19th century, German map of the occurence of Slavic tribes in 850 AD, cerated by the famous Polish historian Joachim Lelewel. CBN Polona shares an ethno-mythological draft of a certain group – Baltic Slavs. On the other hand in the Digital Repository of Scientific Institutes we read a description of Slavic beliefs “revived from the ceremonies, legends, folk songs, sorcery, chronicles and Slavic speech”. Similar subject can be found in the object from 1908, Słowianie: uroczystości i obrzędy (eng. Slavs: ceremonies and rituals) of the School Youth Library series from the Jagiellonian Digital Library. The Radom Digital Library offers an interesting and detailed book about Slavic family rituals connected with the child birth, moreover the Silesian Digital Library gives a chapbook about the Slavic apostles: Cyril and Methodius published in 1885 for the thousandth anniversary of Saint Methodius death.
