DOI Persistence Risk: Landing Pages Becoming Inaccessible in Some Repositories

[Pogrebnoj-Alexandroff]

I would like to raise a cross‑agency concern regarding DOI persistence and the long‑term reliability of DOI landing pages.

There are increasing cases where repositories restrict access to previously open works, including materials with assigned DOIs. The DOI continues to resolve, but the landing page becomes empty, inaccessible, or paywalled. This creates a systemic vulnerability for the DOI ecosystem as a whole.

Although the affected DOIs are registered through DataCite, the issue appears relevant to the broader DOI community, including Crossref, because:

• DOI persistence depends on repository accountability,
• landing page accessibility is essential for metadata integrity,
• citation verification becomes impossible when content disappears,
• FAIR Accessibility and Reusability are compromised,
• and the trustworthiness of persistent identifiers is weakened.

I would like to suggest that this topic be considered for cross‑agency discussion or future recommendations, as it affects the global DOI infrastructure and the reliability of scholarly communication.

Thank you for considering this issue.
