Errata sheet

Each author receives his or her article for proofreading before final publication. Please do it on the text and carefully fill in the errata sheet (download a file). At this stage, minor changes and corrections can be made, which do not affect the composition of the whole material. Filling in the errata sheet is essential so that nothing is omitted and all the author's comments are incorporated into the text. Please return the errata sheet as soon as possible to the journal's email address (collectanea@op.pl) or to the editorial secretary (adriana.grzelak-krzymianowska@uni.lodz.pl). Failure to send the errata sheet within two weeks after receiving it, results in publishing the article in the form proposed by the Editorial Board.
