The french national Couperin consortium conducts each year a large-scale survey among its members to monitor and analyze the costs related to scientific publications from French laboratories. This survey covers the costs associated with immediate open access publication of scientific articles (APC), as well as other related expenses such as color illustrations and page overlength charges. Since 2017, approximately 80 institutions have participated each year, with over 26,400 APCs recorded, totaling nearly 50 million euros. During this presentation, we will discuss the methodology implemented by the consortium for data collection using accountingsoftware, ensuring precise and comparable results between institutions. We will also cover the channels for disseminating the collected data to ensure maximum transparency, accessibility, and value, as well as the challenges of collecting these data on a national scale in a particularly complex landscape.
