Abstract While research on open access (OA) policies has expanded in recent years, systematic research examining the textual content and specific policy elements remains limited, particularly for books. Drawing on a review of existing research and an analysis of sixty-six recent OA book policies, this study introduces a novel methodological framework for structured policy analysis and maps the current OA book policy landscape in Europe. Our results reveal substantial heterogeneity in the policy environment, with variation both in the presence of policy elements and in their operationalization across policies. This diverse policy environment creates implementation challenges at multiple levels, from researchers managing different requirements to institutions developing support strategies, and publishers adapting their services to meet varied policy demands. Given that OA policies significantly impact research practices at individual, institutional, and national levels, yet systematic evidence remains scarce, our findings emphasize the need for increased research and monitoring in this domain.
