ArXiv.org does not assign DOIs to its preprints, but ResearchGate does. Are there other preprint repositories that assign DOIs for free?

  • @TheGuy Yes, I've assigned them to my own preprints. See: ResearchGate DOIs. Try adding a preprint here; it should let you assign a DOI.

  • Why do you want a DOI on sth. that is not 100% final? They are unique and permanent, so you're supposed to keep the target available in perpetuity.

  • @Karl According to ResearchGate, "DOIs help you: • Make your research citable. • Put a date on your discovery." Also, RG's "DOIs can be generated for most of your unpublished work."

    So is this question an ad for research gate or...?

    I suggest editing the question to essentially "where to obtain a DOI for a preprint for free?" Jun 2 '18 at 15:30

Although meant for data, the Zenodo repository assigns free DOIs. Nothing hinders one from uploading PDFs there.


Biorxiv (the main life sciences preprint server) gives DOIs.

  • ChemRxiv does that too

No preprint server should be charging authors any fees for DOIs? I would also +1 for BioRxiv or the Open Science Foundation has 18 different subject-based preprint repositories that might fit yours.


There is a community-curated list of preprint servers, and it takes note of which identifier is assigned to content - you can filter those by DOI.


Zenodo is a repository that assigns DOIs for free. You can access it via your GitHub account or ORCID ID.
