On 13-14 September 2021 the 39th Problem Conference of Medical Libraries was held in Olsztyn, organized by the Library of the University of Warmia and Mazury. One of the sessions at the conference covered the topic of open medicine. The session was added to the conference programme due to many suggestions from the participants of another conference that summed up the implementation of two projects carried out under the Operational Programme Digital Poland for 2014-2020 – “Polish Platform of Medical Research: a knowledge and research potential management platform” and “InterScienceCloud – integrated platform of information about the scientific activities of the Medical University of Łódź”. Taking up the topics discussed at the previous conference, the session on open medicine at the 39th Problem Conference in Olsztyn dealt with current research information systems, institutional repositories in Polish medical institutions, open access policies implementation and PPM integration with ORCID, among other topics.
