ENShortly after the death of prof. Stanislaw Kościalkowski, a group of his Vilnius students decided to publish memoirs about their Master. They collected materials, including manuscripts of memorial texts, obituaries, press clippings and several photographs, most probably for the prepared publication - a type of Memorial Book. In 1973 the documentation has been transferred to the Manuscript Department of the UMK University Library. These materials were not used by any of the researchers and were never published.
