Shodhganga is India’s national digital repository of PhD theses and dissertations, developed and maintained by the Information and Library Network Centre (INFLIBNET), an autonomous inter-university centre of the University Grants Commission (UGC) under India’s Ministry of Education. Since 2016, depositing an electronic copy of a completed PhD thesis into Shodhganga has been a mandatory step in the doctoral award process at Indian universities, not an optional archiving service. For a research administrator, librarian, or doctoral candidate working with Indian institutions, understanding how Shodhganga fits into that regulatory workflow — and how it differs from the related synopsis repository Shodhgangotri — is basic operating knowledge.
What Shodhganga is
Shodhganga (from Sanskrit/Hindi roughly “river of knowledge”) is a full-text digital repository built on DSpace, the open-source repository platform originally developed by MIT Libraries and Hewlett-Packard. INFLIBNET launched Shodhganga in 2010 following a 2009 UGC directive encouraging universities to make theses available electronically. As of mid-2026 the repository holds well over 600,000 full-text theses contributed by several hundred participating Indian universities, making it one of the largest single national ETD (electronic thesis and dissertation) collections in the world.
Each record in Shodhganga typically includes the full thesis PDF, bibliographic metadata (title, author, university, department, supervisor, year of award), and an abstract. Content is made available for open access, and the repository itself states theses are offered under a Creative Commons licence framework rather than all rights reserved — researchers should still check the licence terms attached to an individual record before reusing text, rather than assuming blanket permission.
The UGC regulation that made deposit mandatory
The mandate behind Shodhganga is the UGC (Minimum Standards and Procedure for Award of M.Phil./Ph.D. Degrees) Regulations, 2016, notified on 5 May 2016. Among other requirements for the doctoral process (course work, comprehensive examination, open defence, plagiarism checking — see below), the 2016 Regulations require that a soft copy of the successfully defended thesis be submitted to INFLIBNET for hosting on Shodhganga, so that the full text becomes accessible to other institutions and researchers nationally. In practice this means a candidate’s degree paperwork is not treated as complete by the university until the electronic thesis has actually been transmitted to and hosted on Shodhganga — it is a formal step in the award pipeline, not a courtesy copy for a library archive.
Because the requirement sits inside a UGC regulation rather than an individual university statute, it applies uniformly across UGC-recognised universities awarding the PhD, which is a large part of why Shodhganga’s coverage is as broad as it is compared to institutional repositories in most other countries, which are typically voluntary or policy-driven rather than regulation-mandated.
How a thesis actually gets from a scholar to Shodhganga
The deposit workflow runs through the university, not directly from the candidate to INFLIBNET:
- MOU and coordinator. A university signs a memorandum of understanding with INFLIBNET and designates an institutional coordinator (typically in the university library) responsible for Shodhganga submissions.
- Post-defence submission. After a candidate successfully defends and the university finalises the award, the candidate or department supplies a soft copy of the final, corrected thesis to the coordinator, generally alongside the physical/library copy already required by the university.
- Metadata and verification. The coordinator checks the file and compiles the required metadata (author, title, supervisor, department, year, subject classification) before upload.
- Upload to Shodhganga. The coordinator uploads the thesis and metadata into the DSpace-based repository under the university’s designated collection.
- Indexing and access. Once processed, the thesis becomes searchable and downloadable through Shodhganga’s public interface, and is picked up by search engines and aggregators that index open repositories.
Because the coordinator role sits with each university rather than with INFLIBNET centrally, the speed of a given thesis appearing on Shodhganga after a defence varies by institution — a research administrator advising a candidate should check with the home university’s library on typical turnaround rather than assume a fixed national timeline.
Searching and accessing theses
Shodhganga is searchable directly at shodhganga.inflibnet.ac.in by keyword, author, guide/supervisor, university, subject, and year. Because it is a DSpace repository, records are also organised into browsable collections by contributing university and department, which is often a faster route than keyword search when a reader already knows the institution. Most records are full open access: the complete PDF can be downloaded without a login or subscription, which is the main practical difference between Shodhganga and subscription-only proprietary dissertation databases used in some other countries.
Embargo and restricted-access provisions
Not every thesis on Shodhganga is available as unrestricted full text from the moment it is deposited. Universities can withhold or restrict access to a thesis for a defined period in specific circumstances — most commonly where the candidate or institution intends to file a patent application based on the thesis research and premature open disclosure would jeopardise that filing, or where a sponsor or collaborating organisation has a confidentiality interest in the findings. In these cases the metadata record (title, abstract, author, university) is generally still listed, but the full-text file is withheld until the restriction period lapses or the university authorises release. A candidate or supervisor who anticipates needing this kind of restriction should raise it with the university’s Shodhganga coordinator and research office before the thesis is finalised for deposit, since it is handled as part of the university’s own submission process rather than something INFLIBNET arbitrates after the fact.
Shodhgangotri: the companion synopsis repository
Shodhgangotri is a separate, related INFLIBNET repository that should not be confused with Shodhganga. Where Shodhganga hosts completed, awarded full-text theses, Shodhgangotri archives the synopsis and research proposal a scholar submits at the point of PhD registration — the outline of intended research submitted to the university (and, in most Indian doctoral processes, circulated for approval before full-scale work begins). In other words:
- Shodhgangotri = research proposals/synopses, deposited near the start of a doctoral programme, describing work still in progress.
- Shodhganga = completed, examined, awarded full theses, deposited after the degree is conferred.
Shodhgangotri is considerably smaller than Shodhganga and serves a different purpose: it lets other researchers and institutions see what doctoral research is currently underway across Indian universities — useful for spotting duplicate or closely overlapping research topics early — whereas Shodhganga is the completed-research record. A research administrator advising a new PhD registrant about deposit obligations should be clear about which of the two repositories applies at which stage of the candidature.
How Shodhganga connects to UGC’s anti-plagiarism regulations
Shodhganga deposit is administratively linked to, but distinct from, the plagiarism-check requirement under the UGC (Promotion of Academic Integrity and Prevention of Plagiarism in Higher Educational Institutions) Regulations, 2018. The 2018 Regulations require every thesis and dissertation to be checked against a UGC-approved similarity-detection tool before submission, with tiered similarity thresholds and defined disciplinary consequences for exceeding them. That check happens as part of the university’s internal pre-submission and examination process, before the final, cleared thesis is passed on to the Shodhganga coordinator for deposit. Shodhganga itself does not run the similarity check and is not the enforcement mechanism for the 2018 anti-plagiarism regulations — it is the archival and public-access step that follows a thesis clearing that process and being awarded. The two regulatory strands (2016 deposit mandate, 2018 plagiarism mandate) are complementary parts of the same UGC doctoral-quality framework rather than the same rule under two names, and a research administrator explaining the process to a candidate should keep them distinct: similarity checking happens before award and belongs to the 2018 Regulations; Shodhganga deposit happens at or after award and belongs to the 2016 Regulations.
Why this matters for research administrators
Shodhganga functions as a de facto national doctoral-output register for India: it is often the fastest way to check whether a specific thesis exists, confirm a claimed PhD’s title/university/year, or survey prior work in a subject area across Indian universities before a new candidate’s synopsis is approved. For international collaborators and funders assessing an Indian partner’s track record, Shodhganga sits alongside VIDWAN, INFLIBNET’s national expert-and-researcher database, as one of the two flagship pieces of INFLIBNET-run research infrastructure worth knowing by name: VIDWAN identifies the people, Shodhganga archives the completed doctoral output. Neither is an ORCID or DOI substitute — they are India-specific national infrastructure that sits alongside, not instead of, the international persistent-identifier ecosystem.
Frequently asked questions
Is depositing a thesis on Shodhganga mandatory for every Indian PhD?
Yes, for degrees governed by the UGC (Minimum Standards and Procedure for Award of M.Phil./Ph.D. Degrees) Regulations, 2016 — which covers UGC-recognised universities awarding the PhD. Deposit of the electronic thesis to INFLIBNET/Shodhganga is one of the regulation’s defined steps in the award process, not an optional archiving choice left to the candidate or department.
Who actually uploads the thesis — the candidate or the university?
The university, through a designated Shodhganga coordinator (typically in the library), uploads on the candidate’s behalf after the thesis is finalised and the degree is awarded. The candidate supplies the final soft copy and required details, but the account and upload process sit with the institution, not the individual scholar.
Can a thesis be kept off Shodhganga, or access restricted, for patent reasons?
Universities can withhold or delay full-text access for a defined period in specific circumstances, most commonly a pending patent filing or a sponsor confidentiality interest. This is handled through the university’s own research office and Shodhganga coordinator as part of the submission process, and should be raised before the thesis is finalised for deposit rather than after.
What is the difference between Shodhganga and Shodhgangotri?
Shodhgangotri archives synopses and research proposals submitted near the start of a doctoral candidature — work still in progress. Shodhganga archives completed, examined, and awarded full theses. They are separate repositories serving different stages of the same doctoral pipeline.
Does depositing on Shodhganga replace the UGC anti-plagiarism check?
No. The similarity/plagiarism check required under the UGC 2018 anti-plagiarism regulations happens earlier, as part of the university’s internal pre-submission and examination process. Shodhganga deposit is a separate, later step under the 2016 degree-award regulations, applying once the thesis has already cleared examination and any required similarity screening.
Is Shodhganga the same organisation as VIDWAN?
They are both run by INFLIBNET, the same UGC-affiliated centre, but serve different purposes. VIDWAN is a searchable database of researcher/expert profiles. Shodhganga is a repository of completed PhD thesis full texts. An individual researcher may appear in VIDWAN while also having a thesis archived in Shodhganga — the two systems are not interchangeable and are not automatically linked record-to-record.
