Kilka uwag o wykazach oficjałów i otoczeniu biskupów pruskich w średniowieczu na marginesie pracy Marca Jarzebowskiego

The aim of the article is to confront the results of M. Jarzebowski’s research with the achievements of the most recent historiography. The main emphasis was laid on the widely understood surrounding of bishops of four Prussian dioceses, particularly on bishop officials. The German scholar presented readers with an incomplete list of Prussian bishops’ officials in the Middle Ages due to the fact that he did not know the literature of the subject and treated the sources used in his PhD thesis selectively. The comparison of the results of M. Jarzebowski with research of other scholars, both Polish and German, showed a large number of mistakes and misrepresentations in the author’s registers. Leaving the material as it is without underlining errors would be a mistake, which could lead to the registers’ being used by an inexperienced researcher. This, in turn, might lead to many contortions, which would be undoubtedly harmful from the scientific point of view.
