They may have improved the public's perception of academics and related institutions by raising their value creation, reputation, prestige, and visibility. Despite the importance and fast development of investigations, few people have attempted to systematically evaluate and synthesise the effects of previous projects, or to assess the present state of studies in this field. This paper's main aim is to offer a better knowledge and in-depth overview of the present state of research on IRs. The work linked to institutional repositories was carefully organised using a systematic review (SLR) and a methodology. Researchers and universities may benefit from institutional repositories by improving their exposure, reputation, ranking, and public worth. Despite the potential advantages of colleges establishing institutional repositories (IRs).
