Institutional Repositories: Preserving and Sharing Research Globally

Every year, India’s universities and research institutes produce a staggering volume of knowledge: doctoral theses, journal articles, conference papers, technical reports, and datasets. For decades, much of this work disappeared behind subscription paywalls or sat forgotten on library shelves and personal hard drives. Institutional repositories changed that. They are the digital archives that capture an institution’s intellectual output, preserve it for the long term, and make it freely available to anyone with an internet connection. If you have ever downloaded a free full-text thesis from an IIT or read a research paper hosted by an Indian research lab, you have already used one.

What are institutional repositories? 🔗

An institutional repository (IR) is a digital archive that collects, preserves, and disseminates the intellectual output of a single institution, particularly a research or academic body. The most widely cited definition comes from Clifford Lynch, who described an IR as a set of services a university offers its community for managing and distributing digital materials created by that community. In simpler terms, it is the institution’s official home for everything its scholars produce.

Repositories are best understood as a specialised type of digital library. They perform the core functions of any library: collecting, cataloguing, curating, preserving, and providing access to content. The difference is that the content is born digital and tied to one institution, and access is usually open to the public rather than restricted to subscribers.

What goes into a repository? 🔗

The content of an IR is broad. It typically includes pre-prints (articles submitted for publication), post-prints (the accepted text of published articles), final published versions where permitted, conference papers, technical reports, theses and dissertations, and increasingly research datasets. A significant share of repository content is what librarians call grey literature: working papers, reports, and theses that are valuable but were never formally published and are otherwise easy to lose.

Material reaches the repository in two main ways. In the self-archiving model, researchers upload their own work. Alternatively, repository administrators collect documents and deposit them on the authors’ behalf. In practice, many Indian repositories rely heavily on the second approach because self-archiving habits are still developing among faculty.

The role of repositories in academic publishing 🔗

Institutional repositories sit at the heart of the open access movement. Traditional scholarly publishing locks most journal articles behind subscriptions, so a paper is invisible to anyone whose library cannot afford the journal, and it usually will not surface in a general search engine. Repositories invert this. By depositing a copy of their work in an open archive, researchers practise what is known as green open access, making their findings freely accessible and discoverable through search engines without abandoning the journals they publish in.

This matters enormously for a developing country. Open access was conceived partly to solve the problem of inaccessibility caused by financial constraints, which hit research communities in developing nations hardest. Repositories give institutions ownership of their own scholarly record instead of surrendering it permanently to commercial publishers. Much of this technical revolution rests on free, open-source software: DSpace, released in 2002 by MIT and HP, and EPrints are the two platforms behind most repositories in India and around the world.

Examples of institutional repositories in India 🔗

India was an early and enthusiastic adopter of the repository idea. A major push came in 2009, when the Council of Scientific and Industrial Research (CSIR) directed all of its laboratories to set up open access repositories, followed by a national open access policy released jointly by the Department of Biotechnology and the Department of Science and Technology in 2014. Below are some of the most significant examples.

ePrints@IISc, Indian Institute of Science 🔗

The story of repositories in India effectively begins in Bengaluru. The Indian Institute of Science set up ePrints@IISc in 2002, and it is widely regarded as the first OAI-compliant institutional repository in the country. Built and maintained by the institute’s information centre, it was designed to give open access to the research publications of one of India’s premier scientific institutions.

The repository holds a diverse collection of peer-reviewed journal articles, conference papers, technical reports, and theses. IISc also runs ETD@IISc, a dedicated archive for electronic theses and dissertations. The motivation was explicit and evidence-based: studies had already shown that articles in open access repositories attract more citations than subscription-only papers, so making the institute’s output openly available directly served its researchers’ interests.

Repositories at the Indian Institutes of Technology 🔗

The IITs, India’s flagship engineering and technology institutions, have built some of the most active repositories in the country. IIT Bombay developed an early DSpace-based repository to house articles and papers produced on its campus, and IIT Delhi runs its own EPrints-based archive. These systems collect the research generated across departments and make it available to the global academic community, supporting the institutes’ reputation for cutting-edge engineering and science work.

IITs have also contributed to repository knowledge in India in another way. Faculty and librarians at institutions such as IIT Kharagpur have documented how to build communities and collections within DSpace, helping other Indian institutions learn from their experience. The result is a growing network of repositories that collectively make a large share of Indian engineering research freely available.

OpenMED@NIC, National Informatics Centre 🔗

OpenMED@NIC is a slightly different and historically important case. Established by the National Informatics Centre in New Delhi in March 2005, it is a subject-based repository for medicine and allied sciences rather than a single-institution archive. It accepts scholarly work from any professional or researcher in the relevant fields, which makes it a cross-institutional repository.

One feature set OpenMED@NIC apart: it organised its content using MeSH (Medical Subject Headings), the standard biomedical classification system, which made its subject categorisation unusually sophisticated for its time. Built on EPrints, it demonstrated how the repository model could extend beyond individual universities to serve an entire discipline, and it remains a frequently studied example of subject repository design in India.

These three examples sit within a much larger ecosystem. India hosts repositories at the Indian Statistical Institute, CSIR laboratories such as the National Chemical Laboratory and the National Physical Laboratory, the Indian Institute of Astrophysics, and many universities. There are also national-level theses initiatives that complement institution-level archives.

Benefits for scholars and institutions 🔗

The case for repositories rests on three closely linked advantages: accessibility, long-term preservation, and visibility. Each benefits researchers and their institutions in different but reinforcing ways.

Open accessibility 🔗

The most immediate benefit is free access. Whereas most journal articles are available only to subscribers and stay hidden from general search engines, a paper in a repository is fully accessible to the public at no charge and indexed by search engines like Google Scholar. For students and researchers at less wealthy institutions, who cannot rely on expensive journal subscriptions, this removes a serious barrier to participating in scholarship. A doctoral student in a small college can read the same primary research as a peer at a well-funded university.

Long-term preservation 🔗

Digital files are fragile. Personal websites vanish, hard drives fail, and file formats become obsolete. A repository provides a professionally maintained, stable home for an institution’s scholarly record. By taking ownership of preservation, institutions ensure their work survives independently of commercial publishers, and platforms like DSpace were designed from the start as platforms for digital preservation. This is especially valuable for grey literature such as theses and technical reports, which would otherwise be easily lost.

Greater visibility and research impact 🔗

Visibility is where the interests of scholars and institutions converge most clearly. For the institution, a repository raises its profile by showcasing the breadth and quality of its research output in one discoverable place. For individual researchers, depositing work brings broader dissemination, increased use, and enhanced professional visibility. Crucially, this visibility translates into measurable advantage: well-managed repositories enhance the discoverability of research and can produce a demonstrable citation advantage for deposited work. More people find the research, more people cite it, and the institution’s standing grows.

A note on the challenges 🔗

Repositories are not without difficulties. Studies have found that several Indian repositories listed in directories are not consistently visible or accessible online, and central repositories sometimes hold relatively few deposited papers. The recurring obstacle is participation: many faculty members are reluctant to self-archive, often due to a lack of awareness or uncertainty about copyright. This is exactly where library and information professionals add value, by raising awareness, training authors to deposit their work, and acting as metadata editors and repository managers.

What do you think? Given the citation advantage and the cost of journal subscriptions, should depositing work in an institutional repository be made mandatory for researchers at publicly funded Indian institutions? And what would it take to convince a reluctant faculty member that self-archiving is worth the effort?
