-- apologies for cross-posting – Dear colleagues, With the Open Science Retreat (OSR) the ZBW brings together international Open Science supporters from different stakeholder groups. Again, we are planning two sessions where we will dive deeply into the topics that are of burning interest to us all. We cordially invite you to join our 9th Open Science Retreat that will be held virtually on 23 & 24 September 2025, 16:00-18:00 CET. It is dedicated to the theme “Diamond OA: Utopian Dream or the Only Fair Future?” Diamond Open Access has gained increasing attention in recent years as a community-led, equitable model for scholarly publishing that aligns closely with the principles of Open Science. But is Diamond Open Access the long-awaited solution for equitable scholarly publishing – or merely an idealistic vision? This retreat critically explores the promises and limitations of Diamond OA, its role in advancing Open Science, and the role of the scientific community in the success of the model. A view on financing models and a spotlight on successful Diamond OA initiatives will provide practical insights into key success factors and persistent challenges. To guide our discussions, we propose the following questions: * What can the contribution of Diamond OA be to addressing current challenges in scholarly publishing and where does its potential end? * What are effective strategies, recommendations, and lessons learnt for implementing Diamond OA models in line with Open Science principles? * What policy and infrastructure conditions are necessary to ensure Diamond OA can flourish? Don't miss out on this opportunity and apply now for free for this unique networking event: openscienceretreat.zbw.eu<https://openscienceretreat.zbw.eu/> Deadline for application: 2 September 2025 The Open Science Retreat is an interactive event. Participants are expected to commit to active contribution during the entire retreat. The number of participants is limited (random selection, however, balanced with regard to geographical distribution and diversity aspects). We are looking forward to an exciting #OpenScienceRetreat – be part of it!
