1 of 75 checkable references need attention · checked 2026-07-14
At the dated check, the references listed below either did not resolve in Crossref or DataCite, or carried a publisher retraction notice. Each one is shown with the registry record that put it there.
43 without a DOI — not checked. A reference deposited without a DOI is never matched by title or guessed at; it stays outside the checked set, and this line discloses that.

What this badge says. CiteStamped means the CHECKABLE references of this
work were clean at the dated check: each resolved to a known work in a public registry, and none
carried a publisher retraction notice at that time. It says nothing about the quality, findings,
or importance of the work itself, and nothing about references deposited without a DOI.
checked 2026-07-14 — re-checked daily as this page is visited; titles and statuses come from Crossref and DataCite and are not part of the signed record

Both snippets point at the live badge image and link back to this page. The badge re-renders from the daily check, so an embed never goes stale by more than a day of visits.
