The very first inspiration for the creation of the atlas of Poland in 16th century revealed in early eighties, 19th century. In 1953 a Section of the Historical Atlas in the Institute of History, Polish Academy of Sciences was established. An original concept of the Atlas was improved in 1964 and a new series was introduced (‘Historical Atlas of Poland. Detailed Maps of the 16th century’), with a firm list of volumes and an order of their publication: ‘Lublin Voivodeship in a second half of the 16th century’ (1966), ‘Masovia in the second half of the 16th century’ (1973), Sandomierz Voivodeship in the second half of the 16th century’ (1993), ‘Sieradz and Leczyca Voivodeships in the second half of the 16th century’, (2008), ‘Greater Poland in the second half of the 16th century’ (2017). At present three new volumes are being prepared. Kujawy with Dobrzyn Land and Podlasie are going to be issues first, according to the methodology from the Greater Poland volume. When it comes about a Royal Prussia, a volume edited by Marian Biskup in a cooperation with Lucjan Koc and published in 1961 is going to be supplemented and adjusted to the series of detailed maps. All three are going to be printed in 2020. The data collected during the work on the project are made available in form of a spatial database (downloadable) presented in a GIS application – interactive form of main maps which were published in series till now. Also starting from Greater Poland volume the digital editions of tax registers from 16 c. were prepared and in this moment digital index of the first section of The Crown Treasure Archive is being elaborated.
