The Ghost Check: A One Source Provenance Audit

A 2026 arXiv preprint found 1,655 fabricated author records on Zenodo carrying real DOIs, backdated, indexed, and harvestable by any scholarly aggregator. They pass the source check most of us teach. This is the check that still works, done by hand, on one source you actually assigned.

Pick one source. A reading on next week’s syllabus, or a citation from a student paper you are grading. Work through five questions. You finish holding a written verdict.

SEED
The source

1. Paste the source exactly as it appears on your reading list or in the student’s bibliography.

Copy it verbatim, including anything that looks slightly off. The formatting itself is sometimes the tell.

SPROUT
The venue and the person

2. Does the venue exist independently of this record? Look for an ISSN, an editorial board with people you can find elsewhere, and an archive of other issues. Write what you found.

A very large share of the Zenodo ghost records name journals that exist nowhere except on the record itself.

3. Does the author exist somewhere that is not a publishing aggregator? An institutional page, a conference program, a dissertation, a grant, a course listing. Write what you found and where.

ResearchGate, Google Scholar and Semantic Scholar index without verification, so a profile on any of them confirms nothing on its own.

GROW
The timeline and the conversation

4. Does the timeline hold? Compare the stated publication date against when the record first appears anywhere, and against when anything started citing it. Write any gap you find.

Deliberate backdating is what the researchers used to identify the ghost records. A citation trail that begins after the alleged publication rather than during it is the same signal.

5. Has anyone independent engaged with it? A citation from a source you already trust, a critique, a reply, a correction. Write the strongest one you can find, or write that you found none.

Real scholarship gets argued with. Manufactured scholarship sits in silence.

HARVEST
The artifact and the verdict

6. Can you get the artifact behind the claim? The data, the instrument, the appendix, the preregistration, the full text itself. Write what you were able to actually open.

This is the strongest test and the one most often skipped. It is what turns a citation into something a reader can check.

7. Your verdict, in one observable sentence. Not a feeling. Something another instructor could act on. Then say what you will do with this source.
