Abstract
The global trend of establishing digital repositories in institutions of higher education has
accelerated as they are becoming important to research and scientific institutions for
evaluating criteria. Institutional repositories can also help promote the practical impacts of
research, which is not only beneficial to the community but can help demonstrate the
importance of the work and enhance the researcher’s reputation. As of August 2019, the
Directory of Open Access Repositories holds 4 140 repositories, including 15 from Algeria,
consisting theses, conference papers, books and journals. This paper aims to discover the
benefits and impacts of institutional repositories and their role in supporting scientific research
and enhancing the global visibility and impact of grey literature through answering the following
questions: What are the best practices to improve the visibility of grey literature? How can we
achieve high grey literature visibility in Algerian institutional repositories?
