The mandate of the current steering committee of the IFToMM Permanent Commission for the History of Mechanism and Machine Science (PC-HMMS) ends in 2023, after two consecutive terms. This paper is aimed at summarizes the activities and results of the PC-HMMS by all its members in these six years (2018–2023). It is intended to be a brief final report - the first to date - to constantly monitor the state of health of the commission. In particular, the focus is on the editorial activity of the PC that has been developed on two main tracks: the publication of monographs and related books on HMMS, and the publication of the proceedings of conferences and workshops related to the HMMS topics. The paper, without claims of completeness, is intended to be a moment of reflection on what has been done and a starting point for the activity of the next board of the IFToMM PC-HMMS.
