An Institutional Repository is an online locus for collecting, preserving, and disseminating, in digital form, the intellectual output of an institution, particularly a research institution.

For DLIS NBU, this would include materials such as research journal articles, peer reviews, and digital versions of theses and dissertations, but it might also include other digital assets generated by normal academic life, such as administrative documents, and course notes, or learning objects.

This departmental repository is published online and is basically open to the public. While most academic resources are available only to subscribers and not retrievable by general search engines, such as Google, research papers in an institutional repository are fully accessible by the public free of charge and are accessible by general search engines. Popular software such as DSpace, EPrints, and Bepress are also open sources. As of May 2022, there are about 56 resources in this repository.
