About This publication is part of the IP4OS Profession Deepening Modules and focuses on the Role of Librarians. It consists of an expert panel video “IP & OS — Managing Copyright and Licensing for Reuse” and an accompanying exercise “Advising Researchers on Openness, IP, and Knowledge Valorisation.” Together, both resources (can be downloaded in this publication) serve as a valuable Open Educational Resource for European library staff, broadening the perspective on librarians' working reality in the context of Intellectual Property, Open Science, and Knowledge Valorisation. It highlights how library professionals support researchers to make informed decisions that balance Open Science practices with commercialisation to maximise social and economic impact. Core Goal Librarians will be equipped to act as first-line advisors in IP-OS implementation—capable of navigating copyright, licensing, and rights retention to ensure compliant and impactful dissemination of research outputs, as part of a multi-professional team. Learning goals By completing this unit, participants: Understand core Intellectual Property and Open Science interactions in publication workflows and beyond. Can explain the three minimal knowledge valorisation skills in their context. Identify one concrete institutional improvement for Open Access compliance that also aligns with knowledge valorisation goals. We recommend watching the video first and then deepening your knowledge through the short follow-up exercise “Advising Researchers on Openness, IP, and Knowledge Valorisation" (download below). The video IP & OS — Managing Copyright and Licensing for Reuse features European librarians Inge Van Nieuwerburgh (communications support, Ghent University library), Stephen Wyber (Stephen Wyber, Director, External Affairs, International Federation of Library Associations and Institutions and IP4OS partner), Alex Felnon (Head of Copyright & Licensing, Libraries & Learning Resources, University of Birmingham), and Chris Morrison (Head of Copyright & Licensing, Bodleian Libraries, University of Oxford) sharing their working realities on research outputs, (funders’) open access and commercialisation requirements, and cross-institutional collaboration on embargoes, sharing decisions, and secondary publishing rights. It emphasises the key role of librarians in guiding researchers through scholarly communication, promoting responsible data management and licensing, and supporting Open Access through measures such as the Secondary Publishing Rights.
