This study investigates the impact of open-source software (OSS) on the sustainability of academic library services in Bangladesh. It aims to understand how OSS can address budget constraints, technological demands and the need for enhanced service delivery in these libraries.

An in-depth qualitative research approach was used, involving semi-structured interviews with library administrators, IT staff and librarians from various academic institutions across Bangladesh.

The study reveals that OSS adoption is primarily driven by financial imperatives and the need for flexible, customizable solutions tailored to specific institutional needs. Key benefits identified include significant cost savings, improved customization and flexibility of services and enhanced community support and collaboration. However, challenges such as a lack of in-house technical expertise, resistance to change among staff and stakeholders and inadequate IT infrastructure impede successful OSS implementation.

To harness the full potential of OSS, academic libraries must invest in capacity building through targeted training programs, improve IT infrastructure and foster a culture of collaboration and knowledge-sharing within the library community. These strategies are essential to overcoming existing barriers and ensuring long-term sustainability.

This research contributes to the understanding of OSS’s role in enhancing the sustainability of academic library services. It provides practical recommendations for academic libraries seeking to leverage OSS for improved service delivery and operational efficiency.
