Transforming library systems in Africa is essential for advancing literacy and preserving cultural heritage in an increasingly digital world. The integration of digital innovation into African libraries has the potential to revolutionize access to information, promote lifelong learning, and safeguard indigenous knowledge. This review explores the role of modern technologies, such as digital archiving, e-libraries, and mobile platforms, in enhancing literacy rates and preserving Africa's rich cultural traditions. By transitioning from traditional, print-based models to digital systems, libraries can bridge the educational gap in underserved communities, offering wider access to educational resources and promoting literacy at all levels. Additionally, digitization facilitates the preservation of local languages, oral histories, and cultural artifacts, ensuring that future generations can engage with Africa's diverse heritage. The challenges of digital transformation in African library systems, including limited infrastructure, funding, and digital literacy, are also discussed. The review emphasizes the need for strategic investments in technology, capacity building, and policy frameworks to create a sustainable digital ecosystem. By harnessing digital innovation, African libraries can evolve into dynamic centers of learning and cultural preservation, contributing to both socio-economic development and the protection of African identities. This transformation is critical to fostering a more educated, culturally aware, and globally connected African society.
