The community of Polish medical libraries has been cooperating on numerous projects and initiatives for many years. Recently, eight libraries have created a joint platform for the promotion of research outputs and research potential of eight medical institutions. The project titled “Polish Platform of Medical Research: a knowledge and research potential management platform” (PPM) was created following the identification and analysis of the needs of the scientific community in the area of medical research. It was implemented between November 2017 and January 2021 under the Operational Program Digital Poland for 2014–2020, co-financed with funds of the European Union in connection with the European Regional Development Fund. This paper presents the assumptions, stages, effects and internal organization of the project as well as the conclusions from this complicated implementation.
