Reference checks before production: fix identity, support and sequence

Lumora Editorial Office · Published 16 August 2026 · Updated 15 September 2026

A reference can look correctly formatted while pointing to the wrong work. A reliable production check therefore starts before punctuation and ends after the manuscript has been renumbered. This guide uses an invented bibliography with no real DOI or PMID values. It demonstrates a review process; it does not measure how many production days the process saves.

1. Preserve the draft you are checking

Save the manuscript version and a reference-library export before making changes. Note whether citations are managed fields or plain text. Work on a controlled copy and keep the original link between each citation and its record. Merging entries directly in a shared library without understanding that link can make later corrections harder to trace.

Define the check’s scope: main text, tables, figure legends and any supplementary bibliography. The fictional draft has 18 reference records. Two are confirmed within the exercise to be duplicate entries for the same work and version. That fact permits a merge; similarity of titles alone would not.

2. Check identity and the statement it supports

ICMJE holds authors responsible for reference accuracy and support for the associated statement. Its guidance calls for bibliographic or original-source verification, clear identification of cited preprints and checks for retracted articles. These are content checks as well as formatting checks; use the target journal’s current requirements for the final presentation.

Compare the actual work’s title, authors, venue, version and identifier with the library entry. Then read the passage needed for the manuscript claim. In the fictional draft, an identifier attached to one record belongs to another work. Do not retain it merely because it resolves. Find the intended source legitimately, or keep the reference unresolved and revise the unsupported claim.

3. Give each error a traceable correction

The worksheet distinguishes four issues. Merging the confirmed duplicate reduces the record count from 18 to 17, but it does not verify the other 16 records or every claim. The wrong identifier remains a separate issue. A preprint must retain its publication state, and a source cited only in a table still needs a place in the manuscript’s citation sequence.

Keep a correction note with the original value, evidence checked, new value and affected citation locations. The case labels below are local teaching labels, not identifiers for actual publications. No fabricated bibliography should be copied from this example into a paper.

On small screens, scroll the table horizontally, or focus it and use the arrow keys.

Four issues in an invented bibliography
Case	Supplied finding	Correction and remaining check
Duplicate pair	Same work and version confirmed	Merge to 17 records; inspect all linked citation fields
Identifier mismatch	Identifier belongs to another work	Remove the wrong pairing; retrieve the intended work before replacing
Preprint record	Entry is mislabeled as a journal article	Preserve the preprint state and verified version information
Table-only citation	First appears in a table cited from the main text	Apply the journal’s sequence rule and recheck after renumbering

4. Apply the style to the correct item type

NLM’s reference examples cover multiple material types and point to Citing Medicine for detailed guidance. Use an example appropriate to the item—such as a journal article, website, dataset or software—rather than forcing every source into a journal-article template. The examples help with structure; they do not supply missing facts about your source.

Confirm the journal’s requirements for author lists, title abbreviations, dates, volume and issue, pages or article numbers, identifiers and access dates where applicable. Enter actual metadata. Do not infer page numbers from a PDF page counter or convert an article number into a page range. Keep abbreviations consistent with the requested style and the identified journal.

5. Read relevant corrections and publication notices

NLM explains how PubMed links citations to errata, retractions, expressions of concern and other related records. Follow a notice relevant to a cited work and assess what it changes about the claim you intend to make. A bibliographic correction and a retraction are different events; do not label them interchangeably.

Record the services and notices actually inspected, with the date. Absence of a warning in an unchecked library entry is not evidence that the work has no notice. If access to a relevant notice fails, retain the limitation and seek a legitimate route to it. This guide has not checked the status of any real article.

6. Check the manuscript after the last formatting change

For the numbered style described by ICMJE, first mention determines numbering, including the placement of tables and figure legends. Rebuild the citation fields after merging the duplicate, then inspect the final text, tables and legends against the bibliography. The journal’s instructions decide the submitted format.

In the fictional case, the count is 17 after the confirmed merge; the identity mismatch is still unresolved until its source is retrieved. Keep that distinction in the handoff. Open the final submission file and inspect a citation before and after the affected area. A clean reference-library export does not prove that the rendered manuscript has no broken fields or stale numbers.
