Zenodo - A universal repository for all your research outcomes

  • What it is

    Share and preserve your publications, data, software and all other scholarship for free in OpenAIRE’s trusted repository hosted by CERN

    Zenodo ( is an open repository for all scholarship, enabling researchers from all disciplines to share and preserve their research outputs, regardless of size or format. Free to upload and free to access, Zenodo makes scientific outputs of all kinds citable, shareable and discoverable for the long term.

    Don’t have an appropriate institutional or thematic repository? Use Zenodo!

    Zenodo is the name derived from Zenodotus, the first librarian of the ancient library of Alexandria and father of the first recorded use of metadata, a landmark in library history.

  • What it does

    • Sharing and linking research: Zenodo provides a rich interface which enables linking research outputs to datasets and funding information.
    • Citeable and discoverable: All uploads get a Digital Object Identifier (DOI) to make them easily and uniquely citeable. All open content is harvestable via OAI-PMH by third parties.
    • Supports versioning: Via a top-level DOI you can support all the different versions of a file.
    • Trusted, reliable, safe: Data is stored at CERN, which has considerable knowledge and experience operating large scale digital repositories. Data files and metadata are kept in multiple online and offline copies.
    • Includes funding information and makes reporting easier: Zenodo allows you to link uploads to grants from more than 11 funders such as European Commission, National Science Foundation and Wellcome Trust. Zenodo is further integrated into reporting lines for research funded by the European Commission via OpenAIRE. Just upload your research to Zenodo, and we will take care of the reporting for you.
    • Includes article level metrics: Tracks attention for scholarship uploaded.
    • Flexible licensing: Zenodo encourages you to share your research as openly as possible to maximize use and re-use of your research results. However, we also acknowledge that one size does not fit all. Therefore, we allow for uploading under a variety of different licenses and access levels.
    • Reviewing: Research materials can set to share with reviewers only, and also embargoed.
    • Software preservation made simple: Zenodo is integrated with GitHub.
    • Supports FAIR principles: Zenodo makes data Findable, Accessible, Interoperable and Reusable.
  • How can I use it?

    Zenodo is for all researchers, scientific communities and research institutions. It is open to all research outputs regardless of funding source.

    Zenodo accepts any file format as well as both positive and negative results.

    Zenodo does not impose any requirements on format, size, access restrictions or licence. Quite literally we wish there to be no reason for researchers not to share!

    Data, software and other artefacts in support of publications may be the core, but equally welcome are the materials associated with conferences, projects or the institutions themselves, all of which are necessary to understand the scholarly process.

    You are responsible for respecting applicable copyright and license conditions for the files you upload.

    You can create and curate your own community for a workshop, project, department, journal, into which you can accept or reject uploads. Consider it your own complete digital repository!

    Share your research output in 3 steps!

    Zenodo offers simple and easy-to-use data archiving with maximum autonomy. The clear web interface allows you to easily upload your content in just a few steps.

    Content, Access and Reuse, Removal and Longevity policies are available here.

  • Technical requirements

    Total files size limit per record is 50GB (max 100 files). One-time 100GB quota can be requested and granted on a case-by-case basis.

    Data stored in the CERN Data Center: Your research output is stored safely for the future in same cloud infrastructure as research data from CERN's Large Hadron Collider and using CERN's battle-tested repository software Invenio, which is used by some of the world's largest repositories such as INSPIRE HEP and CERN Document Server.

    Open in every sense: Zenodo code is itself open source, and is built on the foundation of the Invenio digital library which is also open source. The work-in-progress, open issues, and roadmap are shared openly in GitHub, and contributions to any aspect are welcomed from anyone.

    All meta data is openly available under a CC0 licence, and all open content is openly accessible through open APIs.
