The article is a critical appraisal of one of the most vital publications concerning Norwid and his biography: Kalendarz życia i twórczosci Cypriana Norwida [Norwid’s life and work calendar], published by Wydawnictwo Poznańskie in 2007. This ample publication has 141 publication sheets that is 1816 printed pages (vol. 1 – pp. 800, vol. 2 – pp. 800, vol. 3 – pp. 216). It constitutes an enormous achievement of the Poznan-based Polish Studies milieu. It is a collective publication, developed by a research team headed by Professor Zofia Trojanowiczowa (co-authors being as follows: Elżbieta Lijewska, Zofia Dambek and Małgorzata Pluty, Jolanta Czarnomorska and Iwona Grzeszczak). The author of the review makes a number of corrections as regards dates and facts, yet he approaches the results of the huge collective research effort with a great deal of researcher’s humility, indispensable in pursuit of historical facts. In his analyses, the author employs the contextual apparatus: historical and philological. The author proves that Norwid’s Calendar is an undeniable source of invaluable knowledge, yet he shows that in this kind of research there is always “endless work of History” waiting ahead.
