Direct comparison
Institutional Repository vs. Zenodo
IR ties deposits to your institution's branding and reporting; Zenodo is CERN-run, free, and open to anyone. Compare how to choose and when to use both.
Side-by-side comparison
| Dimension | Institutional Repository | Zenodo |
|---|---|---|
| What it is | A repository run by one institution, usually via its library, holding that institution's own research outputs across all disciplines | A single, CERN-operated, discipline-agnostic generalist repository open to any researcher worldwide |
| Operated by | The host university or research institute itself, typically the library, on platforms such as DSpace, EPrints, or Fedora | CERN, developed under the EU-funded OpenAIRE program; launched 2013 |
| Who can deposit | Faculty, staff, students, and (at some institutions) alumni of that specific institution | Any researcher, anywhere, with no institutional affiliation check |
| Cost | Free to the depositing researcher; funded by the host institution | Free to use, including for institutions; funded via OpenAIRE/EU infrastructure support |
| Disciplinary scope | Multidisciplinary, spanning every field the institution researches | Multidisciplinary by design, with no subject restriction at all |
| Storage / file size | Varies by institution and platform; not centrally standardized | Up to 50GB per record by default, with an additional allowance available on request per Zenodo's published documentation |
| Preservation commitment | Tied to the host institution's ongoing funding and IT commitment; can be at risk if that specific program lapses | Backed by CERN's infrastructure and continued OpenAIRE/EU funding, independent of any single depositor's institution |
| Institutional branding & reporting | Deposit is visibly attached to the institution and often feeds internal research-output reporting directly | No institutional branding; discoverable by subject and metadata, not by depositor affiliation |
| Persistent identifiers | Usually assigns a handle or DOI, depending on the platform and institutional configuration | Assigns a DOI automatically on every deposit, including for each versioned update |
| Software & non-traditional outputs | Supported at some institutions, but not universally configured for it | A strong fit, with a widely used GitHub integration that auto-archives tagged releases as citeable, DOI-bearing records |
| Typical funder fit | Satisfies policies that accept "an institutional or disciplinary repository"; often independently required by an institution's own reporting or assessment exercise | Widely used for EU Horizon Europe compliance and by researchers whose institution has no IR of its own |
| Onboarding speed | Varies; some institutions require library mediation or metadata review before a record goes live | Fast, self-service deposit with immediate DOI minting |
| When it's the better default | When institutional reporting, local mandate, or ETD requirements apply, or when a funder policy specifically rewards institutional deposit | When there's no relevant IR or subject repository, when software or mixed-format outputs are involved, or when broad, affiliation-independent discoverability matters most |
Common questions
FAQ
Can I deposit the same paper or dataset in both my institutional repository and Zenodo?+
Yes, and it's common practice. Deposit locations aren't mutually exclusive — many researchers deposit primary data or software in Zenodo for its DOI and platform stability while also depositing the paper or thesis in their own IR to satisfy institutional reporting or a local mandate, as long as each deposit complies with the relevant publisher self-archiving policy or licence and any embargo period.
Which one should I use if my funder just says an institutional or generalist repository is acceptable?+
Either satisfies that wording. Use your IR if your institution tracks output reporting through it or requires it locally; use Zenodo if you want a single, fast, funder-neutral deposit that isn't tied to a specific institution, or if your institution has no IR at all.
Is Zenodo a replacement for my university's institutional repository?+
Not exactly — they serve overlapping but distinct purposes. Zenodo doesn't provide the institution-specific branding, local curation, or internal reporting integration an IR offers, and an IR won't offer Zenodo's cross-institutional reach or its GitHub-based software archiving. Many researchers use both rather than treating one as a substitute for the other.
Does Zenodo have the same long-term preservation guarantee as my institution's repository?+
The guarantee comes from a different source in each case. An IR's preservation depends on its host institution's continued funding and IT commitment. Zenodo's depends on CERN's infrastructure and continued OpenAIRE/EU funding. Check each repository's current re3data.org listing and CoreTrustSeal certification status directly rather than assuming either one is automatically more durable.
