This study examined knowledge management practices in the academic libraries of Fourah Bay College (FBC), the Institute of Public Administration and Management (IPAM) and the College of Medicine and Allied Health Sciences (COMAHS) at the University of Sierra Leone. Data from 33 participants via questionnaires, interviews and observations revealed significant gaps, including the absence of knowledge categorisation into explicit, implicit and tacit forms. Additionally, knowledge management policies are not well-publicised, resulting in staff’s lack of understanding of their importance. The research underscores the potential benefits of categorising library knowledge, which could enhance the organisation and accessibility of information. Such improvements would be valuable for governments, university authorities, librarians, policymakers, researchers, students and the public, facilitating better knowledge management and access within these academic institutions.
