Abstract
Monitoring systems are essential for tracking the progress in open access (OA) and particularly the goal of transitioning from paywalled to OA publications in many European countries. In this work, we express our opinion about the challenges faced by monitoring dashboards in providing a complete view of the OA status, ensuring accuracy in measuring OA production and achieving efficiency in the entire process. We analyze the characteristics of various monitoring systems from European countries, including the sources of data, formats, visualization methods, update frequencies, granularity and types of access recorded. We conclude by underlining the importance of monitoring systems in showcasing policy implementation, aiding decision-making, ensuring compliance and measuring impact in the pursuit of a more open scholarly landscape.
