This paper examines the role of virtual exhibitions in preserving and presenting cultural heritage, focusing on the University Library "Svetozar Marković" in Belgrade as the case study. Virtual exhibitions serve as an efficient tool for preservation, presentation, and promotion of cultural heritage, offering unique insights into archival, library, and museum materials that traditional systems cannot always provide. Through digitization, these exhibitions ensure permanent protection of physical cultural artifacts while making them accessible to a broader audience, thus reducing the need for direct contact with original items. The study analyzes publicly available virtual exhibitions from the University Library, categorized into three thematic areas: exhibitions dedicated to prominent historical figures, cultural heritage presentations and specific thematic events. These exhibitions demonstrate how digitization can effectively bridge geographical and linguistic barriers while protecting valuable cultural artifacts. The paper highlights how these virtual exhibitions go beyond mere digital transformation, incorporating creative elements that combine biographies, bibliographies, and digitized materials including archival documents, books, manuscripts, and photographs. The results show that the University Library's virtual exhibitions represent a successful model of cultural heritage digitization, effectively democratizing access to national cultural heritage while promoting public engagement and cultural awareness.
