Strategies for Librarians in Promoting Library Resources to Improve Postgraduates' Engagement in University Libraries in South-South Nigeria

University libraries play a vital role in supporting teaching, learning, and research by providing access to diverse information resources. However, their relevance depends largely on how effectively these resources are marketed and utilized by students. This study examined the marketing of library resources for enhanced utilization among undergraduate students in Ogun State university libraries. A qualitative systematic literature review design was adopted, drawing data from peer-reviewed journals, conference papers, and institutional reports published between 2015 and 2024. Databases such as Scopus, Google Scholar, Web of Science, and ResearchGate were searched using keywords including “library marketing,” “librarian strategies,” and “library resource utilization.” Findings revealed that librarians adopt varied marketing strategies such as social media engagement, exhibitions, and user education to promote awareness of library resources. Nonetheless, challenges including inadequate funding, poor infrastructure, and limited marketing skills hinder effective implementation. The study concludes that consistent identification and promotion of library resources, integration of ICT tools, and continuous professional development are essential for improving resource awareness and usage among undergraduates. It recommends strategic marketing practices and institutional support to strengthen student engagement with library resources in Ogun State university libraries.
