Digital library as an organization involves information system (DLMS), Content (digital resources), users (targeted populations), and services (Access methods such as browsing, searching, and downloading). To understand these components more, a model or theory that explain each component is needed to predict the successful implementation of a Digital library. Thus, this study aims to examine digital library models in the literature and to develop an overall model of Digital library as a consolidation of examined existing digital library models. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 was followed. 16 Original articles published in English from 2018 to 2024 which are retrieved from Emerald, Google Scholar, IEEE, Springer, and Wiley online library were selected for final review. Different searching strategies such as advanced/filter searching provided by databases, phrase search and Boolean search are incorporated to refine the search result. From synthesis of 16 studies, the Delone and McLean IS success model is most frequently adopted DL model. Overall, 12 significant constructs from overlap and a combination of other constructs are extracted for the development of the overall model of DL. Facilitating condition is the base influencing factor of overall model of DL implementation and use. As a whole, development of digital library models is more favorable when concepts are mapped together to reduce an ambiguity among concepts. Thus, this study consolidates different findings of DL models by considering relationships among constructs and mapping them with each other to develop a new overall DL model.
