This paper presents a conceptual review exploring the application of information visualization techniques in the context of collection management in libraries. Collection management plays a crucial role in ensuring libraries offer relevant and diverse resources to meet the information needs of users. Information visualization, with its ability to visually represent complex data, has emerged as a powerful tool for enhancing collection management practices. Drawing upon a comprehensive literature review, this paper examines the theoretical foundations, benefits, challenges, and practical applications of information visualization techniques in library collection management. It discusses various visualization methods, such as charts, graphs, and maps, and explores their potential in assessing collection composition, analyzing usage patterns, and supporting decision-making processes. The paper highlights the benefits of information visualization in improving user engagement, optimizing resource allocation, and facilitating data-driven decision making. It also addresses challenges related to data integration, technology infrastructure, and ethical considerations. Through real-world case studies and examples, this conceptual review provides insights into successful implementations of information visualization in collection management. The paper concludes by emphasizing the potential of information visualization techniques to transform collection management practices in libraries, enhancing the accessibility, relevance, and impact of library resources.
