The purpose of the article is to analyze the historical aspects of the formation and development of institutional repositories in higher education institutions of Ukraine and to identify the peculiarities of entering, organizing, and managing scientific and educational information in these digital resources under conditions of digitalization and the implementation of open science principles.

The research methodology is based on the application of historical-logical, systemic, comparative, and structural-functional methods, analysis of regulatory and legal documents in the field of education and science, as well as generalization of practical experience in the functioning of institutional repositories. The empirical basis of the study includes the institutional repositories of Leonid Yuzkov Khmelnytskyi University of Management and Law, Vinnytsia National Agrarian University, and Vinnytsia Humanitarian-Pedagogical College of a municipal higher education institution.

The article identifies the main stages of the evolution of institutional repositories, from the first electronic archives of scientific materials to modern standardized information systems operating on the basis of international metadata standards and information exchange protocols. A comparative analysis of repository types, their functional purpose, content structure, and software platforms, in particular Ubuntu/MySQL and DSpace, is carried out. Differences in the priorities and use of repositories at the university and college levels are substantiated.

It is established that the effectiveness of institutional repositories largely depends on the quality of metadata, compliance with copyright regulations, moderation procedures, and the level of digital competencies of participants in the educational process. The study proves that institutional repositories are an important tool for ensuring open access to the results of scientific and educational activities, increasing the academic visibility of higher education institutions, and integrating Ukraine into the global scientific space.

The article concludes that the further development of institutional repositories requires improving regulatory and organizational support, standardizing content submission processes, expanding the use of internationally recognized platforms, and strengthening the integration of repositories into educational and research activities.
