The proceedings of the Chapter from the times of Copernicus were thoroughly discussed by prof. Alojzy Szorc. Here we present only the most important issues related to their editing. These protocols can be found in the Archives of the Archdiocese of Warmia in Olsztyn, in three small books. Represent only a small part of the contents of individual books, the rest are documents from later times, or of any other nature. The issues contained in them, the current issues discussed at the meetings of the Chapter. They create a picture of life Canons of Warmia, including Nicolaus Copernicus. His name appears in the minutes several times, in situations of quite ordinary.
