HIRMEOS, a EU funded project that aims at implementing added value services on top of open access book platforms in different European countries, almost reaches its end. Thanks to the project, advanced technologies have been implemented on the participating platforms that actually integrate the research monograph in the Open Science paradigm.

My presentation will be an open invitation to the workshop attendees to collectively reflect on the usage of open scholarly monographs in this context
