Having been overlooked for a long time, OA monographs are now increasingly recognised as an important factor in Open Access publishing. National Open Science policies name OA Monogaphs explicitly to help achieve openness in the way research and scholarship are conducted and made available. To support better incorporation of OA monographs in overall OA policies and approaches, Knowledge Exchange, in 2017 and 2018 produced a landscape study on Open Access and Monographs and theresults of a stakeholder survey. Outcomes indicate that there is a crucial need for international concertation and harmonisation among communities. To follow-up Knowledge Exchange invited experts and stakeholders from academic libraries, universities, authors, publishers, EC-officers and others for an international two-day workshop in Brussels. On 8 and 9 November 2018 intense exchanges and brainstorming resulted in the information and recommendations you will find in our latest publication Towards a Roadmap for Open Access Monographs.
