Abstract : Institutional repositories (IRs) are essential digital infrastructures for managing, disseminating, and preserving the intellectual output of academic and research institutions. As key pillars of the open access (OA) movement, they provide a platform for making scholarly work freely available to a global audience, thereby overcoming the financial barriers of traditional subscription-based publishing. This paper examines the evolving role of IRs, analyzing recent developments and comparing their implementation and impact across different geographical regions. Evidence indicates that effectively managed repositories significantly enhance the visibility and discoverability of research, which can lead to a demonstrable citation advantage for deposited works. Furthermore, they provide a crucial function in guaranteeing the long-term preservation of digital scholarly assets. However, the success of an IR is not automatic; it is contingent upon strategic integration with broader institutional OA policies, the establishment of researcher incentives for participation, and the deployment of interoperable services that connect with larger scholarly networks. The use of analytics is also vital for demonstrating value and guiding development. This analysis, drawing on contemporary policy reports and empirical studies, culminates in a series of practical, evidence-based recommendations. For universities aiming to maximize the OA potential of their repositories, these guidelines address critical areas such as policy alignment, user-friendly submission processes, and sustainable resource allocation. The objective is to empower academic libraries and institutions to transform their IRs into more dynamic and effective agents within the global scholarly communication ecosystem.
