This article examines the history of periodicals which have been published in Sandomierz, or had an ongoing interest in the town, since 1816, when the first publication of this kind went into print. Apart from the Polish segment, the article covers periodicals in Latin, German, English, Russian and Dutch. So far c. 230 items on wide range of themes have been sourced to Sandomierz.

The aim of this article is to present the ephemera related to Sandomierz — either by content or place of the publication — whose distinctive trait was the use of the word 'jednodniówka', or single issue, in the title, the subtitle or the contents. Chronologically, this survey ranges from 1918, the date of the first print of this kind to be published, to the last one (known to the au-thors) dated 2002 and does not cover publications in languages other than Polish. The source material gathered in accordance with these criteria comprises a total of 34 single issues, of which ten appeared in the pre-war period and twenty-four after World War II. Themati-cally, ten of them can be classified as political or concerned with social issues; eight are products of trade unions or other professional associations; twelve are aimed at the younger generation; and each of the remaining four has a focus of its own (i.e. military, historical, religious, literary-artistic). In this article all of the single issues are discussed both with regard to their in format (layout) and their content.

The article follows on an earlier publication by the author devoted to the urban development of Małopolska under Boleslaus the Modest (Krasnowolski, 2004–2005, pp. 36–37, 38–39). At the same time, it expands the subject discussed by the author in another work several years ago (Krasnowolski, 2004). The period in question was actually a quarter of a century from 1279 to 1306. The first of these dates marks the start of the reign of Leszek the Black (Leszek Czarny), successor to Boleslaus the Modest (Bolesław Wstydliwy), and the latter — capture of Kraków by Ladislaus the Elbow–High (Władysława Łokietka), efficiently competing with the rulers of Bohemia and exploiting the death of Wenceslaus III of Bohemia (Wyrozumski, 1992, pp. 200–201). Urban development from the time can be considered continuation of the urban development policy of Boleslaus the Modest, yet at a lower dynamic, due to political instability.

The paper discusses the discovery of a single lithic artefact from the Dąbrowa Tarnowska 37 site. The lithic, based on its technological and typological characteristics, can be associated with the Middle Palaeolithic. This is an important find due to the fact that, in the area of the Sandomierz Basin, settlement of that period is confirmed by only a few single finds discovered exclusively in the eastern and central parts of the basin. The lithic has been defined as a Levallois point, although a different interpretation, such as its being a by-product of Levallois core shaping, can not be excluded. It was made of Jurassic flint of undetermined provenance, probably originating from moraines. Precise dating of the find is not possible. It was been found on the surface of fluvioglacial deposit of South Polish glaciation (Elsterian) age. The chronological framework of this glaciation preceded the well-proven use of Levallois techniques in the south of Poland (Biśnik cave, Ciemna cave, Kraków-Zwierzyniec 1).

Stanisław Tabaczyński, a member of the Polish Academy of Sciences, passed away in November 2020. He was one of the most influential theoreticians of
archaeology in post-War Poland. He developed an original concept of the archaeological process at the junction of the Annales school, the Poznań methodological school, and the inspirations from the Italian academic milieu cantered around the Polish-Italian Interdisciplinary Working Taskforce of Applied Sciences in Archaeology and Protection of Cultural Patrimony. Its main components comprised long-term processes, ethnogenetic processes, and the polisemantisation of culture. He understood archaeology as the anthropology of the prehistoric past, outstretched between anthropology and history. He participated and ran numerous excavation projects in Poland and abroad. These comprised excavation campaigns carried out in the large-scale Millennium Research project in Poznań, Wrocław, Biskupin, Kołobrzeg, Grody Czerwieńskie and Nakło nad Notecią. His major achievement was the excavation of the early Medieval Sandomierz. He discovered a glassmaking workshop of the 7–8th centuries on Torcello Island in the Venice Lagoon and participated in numerous field projects in Italy, France, and Algieria. He is the author of numerous books and articles. Among his most important publications are three-volume Theory and Practice of Archaeological Research, Przeszłość społeczna [The Social Past], Neolit środkowoeuropejski. Podstawy gospodarcze [Central European Neolithic. The economic foundations] and Archeologia średniowieczna – Problemy. Źródła, metody. Cele badawcze [Medieval Archaeology. Issues, Sources, Methods, and Research Objectives].

Vegetation changes in the Lower San Valley near Jaroslaw are reconstructed from the Younger Dryas to the present time on the basis of palynological analysis of the peat core. The pollen profile came from a an old riverbed and was supplemented by radiocarbon datings. The Younger Dryas and early Preboreal vegetation was characterised by a high proportion of forest communities with pine (Pinus sylvestris and P. cembra) and birch (Betula), while patches of open area were dominated by the steppe with Artemisia. Climatic amelioration during the Preboreal chronozone led to the rapid spread of elm (Ulmus), which was probably a dominant taxon on the lowest terraces of the valley. Terrestrialization of the water body existing in the palaeomeaner and the subsequent beginning of peat accumulation caused a deterioration in pollen preservation. Hence, the interpretation of the profile section spanning the period between the Boreal and Subatlantic chronozones was seriously disturbed due to selective corrosion and the overrepresentation of Pinus sylvestris type and Filicales monolete sporomorphs. Between ca. 336 and 1152 AD fluctuations in woodland cover were recorded. Important components in those forests, despite the domination of Pinus sylvestris, were Quercus, Carpinus betulus, Fagus sylvatica and Abies alba. The first pollen grains of cereals (Cerealia type) were found before ca. 1605-1414 BC and may be attributed to the agricultural activity of the Neolithic and/or early Bronze tribes. Periods of strong deforestation caused by humans were probably related to the time when the Tarnobrzeska Group of the Lusatian Culture and the Przeworska Culture were active. The first groups of Slavs did not significantly influence the environment, but the subsequent development of those groups led to more visible deforestation, which was triggered after the establishment of Jaroslaw in the 11 th century AD.
