This new edition of the code has been prepared by the Commission for Research Integrity and approved by the General Assemby of the Polish Academy of Sciences in June 2020. Good research practices are presented in the context of data management; research environment; training, supervision and mentorship; research procedures; safeguards; collaborative working; publication; reviewing and evaluation; conflict of interest (CoI). It is now recommended that each scientist file an annual declaration of CoI while the possible need for its addressing will be determined by the leaders of academic/scientific institutions. Violations of research integrity are briefly presented as well as dealing with those violations as well as with allegations of misconduct.

The aim of this article is to present the understanding of social history of Jerzy Topolski, from the theoretical side and as it was used in practical research work. The source basis, aside from the few direct quotes from the historian from Poznan on social history, are mainly analyses of his selected original works and works edited by him. The article also takes note of the discussion surrounding the term ‘social history’ itself and the research scope of social history as a historic discipline or sub-discipline which took place in the second half of the 20th century, which is the period in which Topolski published his works.
