Is Every Citation in Your
Bibliography Real?

A citation can be wrong in ways no spell-checker, grammar tool, or careful re-read will catch: the paper does not exist, the DOI resolves to a different article, the author list was silently altered, or the year and journal were transposed. The reference looks right — real journal, plausible title, well-formatted DOI — so the eye accepts it. Verifying it means checking each entry against an authoritative record, one at a time.

Citation error is not a rare edge case; it is documented and persistent. Eichorn and Yankauer (1987) found that 31% of references in public health journals contained errors. Evans, Nadjari and Burchell (1990) found a 48% error rate across three medical journals. DeLacey, Record and Wade (1985) identified quotation errors in 15% of references in six medical journals. Word processors did not fix this — and generative AI has made it sharper: a majority of ChatGPT-produced references are fabricated or contain errors serious enough to mislead a reader who does not check (Walters & Wilder, 2023, Scientific Reports, doi.org/10.1038/s41598-023-41032-5).

AiCitationChecker verifies mechanically — cross-referencing every entry in your reference list against CrossRef, OpenAlex, and Semantic Scholar, the canonical academic databases — and returns a verdict on each: real and correct, real but mis-described, or not found at all. A 30–50 reference bibliography that takes 1–2 hours to check by hand is done in under two minutes.

• Fabricated papers — a plausible-looking reference for an article that was never published; no record in any database.
• Fabricated or mismatched DOIs — a well-formatted DOI that resolves to a different article, or to nothing at all.
• Wrong or altered authors — the title and journal are real, but the author list was changed (a common AI edit) so the citation misattributes the work.
• Wrong journal, year, or volume — each field checked against the authoritative record and flagged individually, so you know exactly what is off.
• Real paper, garbled citation — the work exists but your entry is transcribed incorrectly; the tool surfaces the clean version to copy.
• Not found — an honest "we could not confirm this" for sources outside the databases' coverage, kept clearly distinct from "this is fabricated."

The checker reads author–year and numbered reference systems, detecting the format automatically:

APA · Harvard · Chicago · IEEE · Vancouver · MDPI · ACS · AMA / Wiley

Mixed-style bibliographies (a common artefact of merged sections or collaborative writing) are handled — each reference is parsed and verified independently.

Below are three real references from the literature on citation accuracy — the same studies quoted above. Paste them as a reference list to see the checker confirm each one against the databases.

Copy the block below, paste it at the Citation Checker, and click Verify. Each entry is matched against CrossRef, OpenAlex, and Semantic Scholar — comfortably within the free daily allowance for a short list like this.

DeLacey, G., Record, C., & Wade, J. (1985). How accurate are quotations and references in medical journals? British Medical Journal, 291, 884–886.
Eichorn, P., & Yankauer, A. (1987). Do authors check their references? American Journal of Public Health, 77, 1011–1012.
Evans, J. T., Nadjari, H. I., & Burchell, S. A. (1990). Quotational and reference accuracy in surgical journals. JAMA, 263, 1353–1354.

All three are genuine and should come back confirmed. To see the checker catch a bad citation, change a DOI digit, a year, or an author's surname before you paste — that entry will be flagged.

Manually verifying a 30–50 reference bibliography takes 1–2 hours. At any academic hourly rate, the tool pays for itself on the first use. References with a DOI cost 1 credit each to verify; those resolved by title search cost 2.75. The live estimate shows the exact cost before you commit.
