An Institutional Repository is a digital archive that collects, preserves, and disseminates the intellectual output of an institution, such as a university or research organization. It typically includes a variety of materials, such as research papers, theses, dissertations, and other scholarly works, making them accessible to the public and promoting academic collaboration. These repositories support open access to research, allowing users to find and use scholarly content without subscription fees. They also help institutions showcase their research achievements and enhance their visibility in the global academic community, contributing to the broader dissemination of knowledge.
