Abstract
Sustainability, encompassing environmental, economic, and social dimensions, is central to creating a more inhabitable future, and the United Nations (UN) Sustainable Development Goals (SDGs) address multifaceted challenges, including information access and education inequalities. Libraries, particularly academic libraries, have a core mission to provide and disseminate sustainable information, positioning them as key contributors to achieving the SDGs. This comparative study investigates the diverse roles of academic libraries in advancing these goals across Azerbaijan, Bosnia-Herzegovina, Greece, North Macedonia, and Türkiye, chosen for their regional proximity and similar socio-cultural and librarianship contexts. Drawing upon survey data, the study explores the involvement of academic libraries in sustainable development within these countries and the factors influencing their engagement. Despite a low response rate, the findings highlight a growing awareness among academic libraries and librarians toward sustainable development, revealing diverse strategies, successful approaches, and challenges encountered. Ultimately, the study underscores the vital role of academic libraries as catalysts for knowledge dissemination, community empowerment, and innovation in advancing the global sustainability agenda, offering valuable insights for policymakers and library stakeholders.
