The objective of the research is to identify the indicators of the digital library in the Metaverse environment. The current research is applied in terms of objective, and a multi-step quantitative Delphi method was used. The statistical population of this research consists of experts in the field of metaverse, digital libraries, information science and epistemology, and information technology engineering. To determine the sample, the judgmental sampling method and the opinions of 10 experts in this field were used. In order to identify the indicators of the digital library in the field of Metaverse, researchers first extracted 75 indicators by reviewing the literature and research background, and then, through a semi-structured questionnaire, the experts were asked to determine the effect of the indicators based on the five-point Likert scale. 75 indicators were identified through background checks and interviews with experts in the fields of metaverse, digital libraries, information science and epistemology, and information technology engineering. These indicators were screened by distributing questionnaires among experts and using the Delphi method, and 28 indicators were selected for the final analysis. This research was categorized by considering 5 dimensions, including economic, human, political, managerial, and technological dimensions. The presence of digital libraries in the Metaverse environment significantly changes the way of providing services, interacting with users, and managing resources. These changes are effective in improving the user experience, increasing the quality of services, and improving the overall performance of digital libraries in this new world. In fact, in the Metaverse environment, digital libraries are permanently available and allow users to access the resources they need at any time and from any place without time and place limitations.
