The article is dedicated to the Królik family from Krakow, who lived in the town from the late 16th century until the first years of the 18th century. The family members initially worked as tailors, later reinforcing the group of Krakow merchants in the third generation (Maciej Królik). Wojciech Królik – from the fourth generation – was a miner in Olkusz. The text omits the most distinguished member of the family, Wojciech’s oldest brother, the Krakow councillor Mikołaj Królik, whose figure has been covered in a separate work. The work shows the complicated religious relations in the family of non-Catholics, initially highly engaged in the life of the Krakow Congregation, but whose members gradually converted from Evangelism to Catholicism. As a result, Wojciech Królik and his siblings became Catholics. This work is complemented by four testaments of family members, with the first, Jakub Królik’s, being written in 1626 and the last one, Wojciech Królik’s, written in 1691.

The article aims to bring us closer to the figure of Roman Nitsch and his activities in the fields of serology and bacteriology. R. Nitsch studied medicine at Jagiellonian University during the years 1893–1898. For ten years, he was an assistant in the Department of Hygiene and Bacteriology at Jagiellonian University. During that time, he participated in the scientific expedition of Joseph Lindley to research the water intake of the Kura River in the Caucasus region, from which a water pipe to the city of Baku was to be built. He carried out intensive scientific research on rabies and completed his habilitation based on this subject in 1907 at Jagiellonian University. In the same year, he applied to the Executive Board of the Academy of Arts and Sciences for a grant from the Wiktor Osławski Fund. He received 620 krone as financial aid as well as 5,000 krone as a scholarship, thanks to which he conducted scientific work from November 1909 until November 1910 in Paris, Berne, Zurich, Munich, Brussels and Berlin, dealing with the theoretical considerations of constructing modern towns and workers’ houses from the perspective of social hygiene.

The collection of early printed books stored in the National Archives in Krakow has not been processed so far. This article aims to approximate the current state of knowledge regarding the contents of the collection. The historic book collection of the Archives, represented by both Polish and foreign printed books covering various subjects, numbers slightly over 650 works issued before 1801. Included in this number are 28 early printed books from the 16th century, 210 from the 17th century and 413 from the 18th century. The oldest one – Liber horarum canonicarum secundum veram rubricam sive notulam ecclesiae Cracoviensis – was issued in 1508 by the publishing house of Jan Haller in Krakow. The origins of the early printed books vary – they come from donations, acquisitions of archival materials as well as purchases. The greatest number come from donations, with the following donors worthy of special mention: Ambroży Grabowski, Józef Seruga and Franciszek Biesiadecki, as well as Józef Muczkowski, Karol Estreicher and others. An invaluable part of the collection (61 works) are the printed books from the library of Hieronim Pinocci (1612–1676), a merchant, royal secretary and diplomat, acquired from the town archives at the end of the 19th century. Many works, especially those concerning the history of Krakow, were also purchased using the funds of the Archives. The early printed books gathered in the library of the National Archives in Krakow create a particularly valuable collection, which may also be a source of information concerning provenance.

Bierczyński (1891–1970), a graduate of law at Jagiellonian University, led the “Falcon” unit, which set off from Wieliczka on 25 August 1914 to join the Legions forming in Krakow. He served in the 2nd Infantry Regiment, participating in the winter offensive of the II Brigade and the tough battles in Carlibaba (17–21 January 1915) and Korolówka (6–7 March 1915). During the fighting, he described the events from the life of a legionary, however, only fragments of his typed journal remain, covering events from 25 August until 21 October 1914, then from 10 January until 9 March 1915 and from 11 to 31 May 1915. They contain interesting information not only about the military activities, but also about the daily life of the legionaries, the view of the organisation of military actions, news about legionaries as well as descriptions of places in which the divisions were stationed.

The archives of the Chamber of Fiscal Administration in Krakow is an independent unit within the structure of the Malopolska fiscal administration. It was established in 2015 based on the employment archives and repository of fiscal records of the Chamber and all tax offices in the Malopolska region, and in 2017 its resources were expanded by the consolidated records of customs and fiscal control offices from the region. At the end of 2020, the archives of the Chamber in Krakow possessed approx. 45,000 metres of records, including around 550 metres of archival documentation. They were taken care of by 25 employees, working in 35 locations and 131 storage rooms throughout the whole region. They include records from a total of 501 organisational units, in which approx. 4,700 clerks and officers worked.The resources of the archives of the Chamber in Krakow consist, to a significant extent, of documentation created by tax and customs bodies in the last dozen years or so, however, the archival materials also include numerous records of bodies that no longer exist, most frequently legal predecessors of, among others, the Regional Liquidation Office in Krakow, the Control-Review Inspectorate in Krakow, the Regional Board of State Income and Financial Control in Krakow, and financial  departments of various national council bureaus e.g. the Krakow-Old Town District National Council Bureau or the Directorate of Customs in Krakow.
