How to Verify That Every Reference in Your Manuscript Exists
One bad reference can cost you a reviewer's trust. As more drafts are written with AI assistance, references that do not exist are turning up more often. Here is how to confirm that each reference is real and that its details are right.
Why verification is now essential
Generative AI can produce plausible authors, titles and DOIs that do not exist — so-called hallucinated references. Lists compiled by hand also contain year typos, wrong journal abbreviations and missing volume, issue or page numbers. Checking references before submission is no longer optional; it is part of the basic routine.
Step 1 — Confirm that each reference exists
Look up each reference's DOI in public databases such as CrossRef, PubMed (NCBI), Europe PMC and OpenAlex, and confirm that a real record comes back. For references without a DOI, search by title, first author and year. If nothing matches, the reference is either fabricated or cited with wrong details — go back to the original source.
Step 2 — Compare the bibliographic details
A reference can exist and still be cited wrongly. Compare it against the authoritative record:
- Authors: surnames, initials, order and the handling of "et al."
- Year, volume, issue, pages: watch for online-first publication, which can shift the year
- Journal name: full name or NLM/ISO abbreviation, as the target journal requires
- Title: sentence or title case, and special characters
Step 3 — Match in-text citations to the list
Find citations that appear in the text but not in the list, orphan references that are listed but never cited, and unfinished placeholders such as "[ref]." In numbered styles, check that citation numbers increase in order of first appearance; in author–year styles, check that the list is alphabetical.
Step 4 — Unify the citation style
Convert every entry to the target journal's style (Vancouver, APA, IEEE, AMA, Nature and so on) and standardize journal abbreviations. A mix of styles looks careless to editors.
Check your references before you submit
Existence, mismatched details, retractions, citation order and orphans — in one pass.
