Broken DOIs are tiny academic potholes with surprisingly sharp edges. You copy a citation, paste it into your paper, and suddenly the link fails, the article has no issue number, or the phrase “Advance online publication” sits there like a blinking dashboard light. Today, you will learn how to repair APA and Chicago citations without panic, guesswork, or citation-generator confetti. In about 15 minutes, you can verify the DOI, identify the publication status, update the reference, and leave a clean trail for editors, professors, reviewers, or your future sleep-deprived self.
Quick Fix Map for Broken DOIs and Early Online Citations
A broken DOI does not always mean the source is fake, withdrawn, or doomed to haunt your bibliography. Most DOI problems are boring, which is good news. Boring problems can be fixed with a repeatable workflow.
In real academic work, DOI trouble usually appears in one of four ways. The DOI link returns an error. The publisher page opens, but the metadata does not match your citation. The article is online but has no volume, issue, or page range yet. Or the article has moved from “advance online publication” to a final issue, while your reference is still wearing last season’s metadata.
I once watched a graduate student spend 40 minutes changing capitalization in a DOI because the link failed. The real problem was a comma copied into the URL. One comma. A tiny typographic pebble in the shoe.
- Confirm whether the DOI resolves.
- Check whether the article has final volume, issue, and page details.
- Use the final version of record when available.
Apply in 60 seconds: Paste the DOI into a clean browser tab using the format https://doi.org/ followed by the DOI string.
Fast repair order
Use this order when a DOI or early online citation looks wrong:
- Remove extra spaces, punctuation, line breaks, and “doi:” labels from the DOI field.
- Test the DOI using https://doi.org/10.xxxx/xxxxx format.
- Open the publisher page and look for final volume, issue, article number, or page range.
- Check Crossref if the publisher page is unclear.
- Update APA or Chicago style only after the source status is clear.
The one-minute diagnostic
| Symptom | Likely Cause | Fix First |
|---|---|---|
| DOI link fails | Bad copy, old resolver format, typo, or inactive registration | Clean and retest the DOI |
| No page numbers | Article is online first or uses article numbers | Check publisher metadata |
| Citation says “advance online publication” | Final issue details may not exist yet | Confirm publication stage |
| Citation generator gives odd formatting | Exported metadata is incomplete or mapped poorly | Edit fields manually |
This is the calm path. No incense, no sacrificial highlighter, no 2 a.m. email titled “urgent citation question????” with four question marks doing all the emotional labor.
Who This Is For, and Who Should Slow Down
This guide is for students, researchers, librarians, editors, faculty, journal assistants, and professional writers who need clean references in APA 7 or Chicago style. It is especially useful when a source is real but the citation feels half-baked, like a cake removed from the oven because the conference deadline started growling.
It is also for anyone using reference managers. Zotero, EndNote, Mendeley, Paperpile, and library databases are helpful, but they are not tiny citation angels. They import what they receive. If the metadata is messy, the output can be messy too.
You are in the right place if
- You have an article with a DOI that does not resolve.
- You found a publisher page that lacks volume, issue, or page numbers.
- Your APA citation includes “Advance online publication,” but you are not sure whether it should.
- Your Chicago note or bibliography entry feels incomplete.
- Your reference manager imported a DOI into the URL field, or a URL into the DOI field.
- You want to clean a reference list before submission, grading, peer review, or publication.
Slow down if the citation is tied to academic integrity
If the source may be retracted, corrected, disputed, AI-generated, duplicated, or not the version you actually read, do not simply “style it pretty.” Accuracy comes before elegance. A polished wrong citation is still wrong, only now it has better shoes.
For wider manuscript preparation habits, you may also want to review your academic writing workflow so citation checking is not left until the final hour, when everyone’s brain has become warm oatmeal.
Academic integrity note
This article is educational guidance, not a substitute for your instructor, journal editor, librarian, publisher policy, or style manual. Citation rules can differ by institution, journal, discipline, and assignment. When the stakes are high, verify the preferred format before submission.

Why DOIs Break Even When the Article Is Real
A DOI is meant to be persistent, but persistent does not mean immune to messy humans, database quirks, or copy-paste goblins. A Digital Object Identifier points to a registered object, usually through a DOI resolver. The resolver then sends the reader to current metadata or a publisher location.
When a DOI breaks, the article may still be valid. The problem may live in the formatting, registration, metadata, publisher transfer, or your reference manager field map.
Common reasons DOI links fail
- Extra punctuation: A period, comma, or parenthesis was copied as part of the DOI.
- Line breaks: A DOI split across two lines was pasted with a hidden space.
- Old DOI format: Older citations may use doi:10.xxxx/xxxxx instead of a clickable https://doi.org/ link.
- Publisher transfer: A journal changed platforms, and the resolver metadata has not aged gracefully.
- Bad imported metadata: A database exported the wrong DOI, incomplete title, or duplicate record.
- Case confusion: DOIs are usually handled without caring about capitalization, but exact copying is still wise.
I once checked a reference list where every DOI failed. The author had exported from a database that inserted a space after every slash. It looked elegant, almost poetic. It was also completely unusable.
What a DOI should look like
Modern APA references present DOIs as URLs. The clean pattern looks like this:
https://doi.org/10.1037/0003-066X.59.1.29
Chicago style also accepts DOI presentation in a URL-style form in many current editorial workflows, though the exact final choice may depend on the publisher, instructor, or journal. The main job is to make the identifier accurate, reachable, and consistent.
Show me the nerdy details
A DOI has a prefix and suffix. The prefix usually begins with 10 and identifies the registrant. The suffix is assigned by the registrant and may include letters, numbers, punctuation, or publisher-specific patterns. The DOI resolver does not replace the publisher page. It routes readers from the persistent identifier to the registered location. If the DOI resolves but the metadata is thin, your citation still needs human review.
Do not confuse DOI failure with source failure
A broken DOI is a warning light, not a verdict. Before removing a source, compare the DOI against the article title, author list, journal page, database record, and PDF first page. If several pieces agree, you are probably dealing with a repair problem, not a fake source.
The DOI Rescue Workflow: Verify Before You Rewrite
The safest way to fix a broken DOI is to treat it like a small metadata audit. That sounds grander than it is. You are not excavating a lost city. You are checking whether the reference points to the article it claims to point to.
Start with the article you actually used. If you read the PDF, open the PDF. If you read the publisher page, open that page. If you used a database abstract, check whether the database links to the publisher’s final page.
Step 1: Strip the DOI down
Copy only the DOI string. Remove:
- Trailing periods
- Parentheses
- Quotation marks
- Spaces after slashes
- The label “doi:”
- Database tracking parameters
Then rebuild the link as:
https://doi.org/[DOI]
Step 2: Search by title when the DOI fails
If the DOI still fails, search the exact article title in quotation marks. Search the title plus the first author’s last name. Search the title on the publisher site if you know the journal.
A small trick from long editing days: copy a unique phrase from the abstract instead of the whole title. Titles can change slightly between accepted manuscript and final publication. A distinctive phrase can work like a fingerprint, but less dramatic and without a detective hat.
Step 3: Compare five fields
| Field | What to Check | Why It Matters |
|---|---|---|
| Title | Exact or near-exact wording | Preprints and final articles may differ |
| Authors | Order, initials, group names | Author order is part of scholarly credit |
| Journal | Full journal title, not just abbreviation | Style rules differ by format |
| Date | Online publication date and final issue year | The reference year may change |
| DOI | Resolver link and publisher metadata | A wrong DOI sends readers elsewhere |
Step 4: Use authoritative metadata, not random mirrors
Publisher pages, Crossref records, PubMed records for biomedical literature, library databases, and journal pages are stronger than scraped citation sites. Scraped sites may repeat errors with the confidence of a parrot in a lab coat.
Step 5: Update the citation after verification
Only after verification should you apply APA or Chicago formatting. This order prevents the classic mistake: beautifully formatting a citation that still points to the wrong object.
- Identity means title, authors, journal, and DOI point to the same work.
- Status means preprint, accepted manuscript, early online article, or final version.
- Style comes last, not first.
Apply in 60 seconds: Add a temporary note beside any doubtful reference: “Verified DOI? Final issue details?”
APA 7: How to Cite Advance Online Publication Articles
APA 7 is practical about online-first journal articles. If the article has been published online but has not yet been assigned volume, issue, or page information, APA allows an “Advance online publication” note in the reference.
The important phrase is not decoration. It tells the reader why the reference lacks final issue details. It also signals that the citation should be checked later if the manuscript remains in revision for a while.
APA pattern for advance online publication
A typical APA 7 journal article reference with advance online publication follows this logic:
Author, A. A., & Author, B. B. (Year). Title of article. Title of Journal. Advance online publication. https://doi.org/xxxxx
Use sentence case for the article title. Italicize the journal title. Include the DOI in URL form when available.
When to remove “Advance online publication”
Remove the phrase when final publication details exist. That usually means the article has a volume, issue, page range, or article number assigned as part of a final journal issue.
Here is the practical test: if the publisher page now shows complete issue placement, update the reference to the final version. Do not keep the early online note as a sentimental souvenir. Citations are not scrapbooks.
APA final article pattern
When final issue details exist, a typical APA reference looks like this:
Author, A. A., & Author, B. B. (Year). Title of article. Title of Journal, 12(3), 45–59. https://doi.org/xxxxx
If the journal uses article numbers instead of page ranges, include the article number where the page range would normally appear, according to the journal’s displayed metadata and APA guidance.
APA repair examples
| Source Status | Reference Clue | APA Move |
|---|---|---|
| Online first, no issue details | Publisher page says “Advance online publication” or “online first” | Use the advance online publication note |
| Final issue assigned | Volume, issue, and page or article number appear | Remove the note and cite final details |
| DOI works but metadata is incomplete | Resolver opens but publisher fields are thin | Check the publisher page and database record |
A small APA caution about dates
Early online articles can show one online date and later appear in a final issue with a different year. In APA, use the date associated with the version you cite. If a final version now exists, the final bibliographic record usually wins.
I have seen manuscripts where half the references used early online dates and half used final issue dates for the same journal cluster. The result felt like a calendar had been dropped down a staircase. One careful pass can restore order.
Chicago: How to Handle Online-Ahead-of-Print Articles
Chicago style gives editors and writers a little more room, which can be both helpful and mildly dangerous. The format may vary depending on whether you use notes and bibliography or author-date style. The guiding principle stays steady: identify the article clearly, include publication status when final details are not available, and provide the DOI when possible.
Chicago users should check whether their instructor, press, journal, or department prefers “published online,” “advance online publication,” “online ahead of print,” or a similar phrase. House style matters. Chicago is a grand old building with many rooms, and some editors keep very specific furniture arrangements.
Chicago notes and bibliography pattern
For a journal article available online ahead of print, a bibliography entry often includes the author, article title, journal title, online publication status or date, and DOI.
A practical pattern:
Author Last Name, First Name. “Title of Article.” Journal Title, published online Month Day, Year. https://doi.org/xxxxx.
If the final volume, issue, and page details appear later, update the entry to the final journal article format.
Chicago author-date pattern
For author-date, the entry usually begins with author and year, then title, journal, publication status or available details, and DOI.
A practical pattern:
Author Last Name, First Name. Year. “Title of Article.” Journal Title. Published online Month Day, Year. https://doi.org/xxxxx.
If final details exist, cite the final journal article instead.
Chicago repair cues
- Use headline-style capitalization for article titles in many Chicago contexts, unless your assignment or press says otherwise.
- Put article titles in quotation marks.
- Italicize journal titles.
- Prefer a DOI over a database URL when a DOI is available.
- Do not invent page numbers because the PDF looks “about 12 pages.” That way lies bibliography soup.
For broader research-writing polish, the habits in advanced literature review searching can also help you catch duplicate records, older versions, and citations that entered your draft through the side door.
Chicago comparison table
| Case | Include | Avoid |
|---|---|---|
| Online ahead of print | Online publication date or status and DOI | Fake volume, issue, or page range |
| Final article available | Volume, issue, pages or article number, DOI | Old early-online language |
| Database record only | DOI and publisher-confirmed details if available | Long proxy URLs from your campus library |
Status Decision Table: Preprint, Accepted Manuscript, or Version of Record?
The hardest citation problems are often not style problems. They are version problems. You need to know what you are holding before you can cite it correctly.
A preprint, accepted manuscript, advance online publication article, and final version of record can share a title and authors while still being different citation objects. Think of them as siblings, not clones.
Version status map
| Version | Typical Clue | Citation Risk | Best Move |
|---|---|---|---|
| Preprint | Posted on a preprint server before peer review | May differ from final article | Cite as preprint unless final article was used |
| Accepted manuscript | Author accepted manuscript, AAM, postprint | May lack final formatting and pages | Use version label when required |
| Advance online publication | Publisher article online before issue assignment | Final details may appear later | Cite early status until final details exist |
| Version of record | Final publisher record with stable article details | Lowest citation ambiguity | Prefer this when available and actually used |
Decision card: which version should you cite?
Decision Card: Cite the Version You Actually Used
Use the final version of record when you read it, downloaded it, or can verify it matches the article you relied on.
Use the advance online publication format when the publisher has released the article but not final issue details.
Use the preprint or accepted manuscript format when that is the version you read and no final version is being cited.
Flag it for help if the versions differ in data, conclusions, authorship, title, or DOI.
If your manuscript touches author rights or posting versions, the distinction also connects to self-archiving choices. The guide on author accepted manuscript self-archiving is a useful companion because it separates manuscript versions without turning your notes into alphabet soup.
Short Story: The DOI That Changed Its Clothes
Maya had a clean literature review, or so she thought. The article she cited had a DOI, an abstract, and a PDF, which felt official enough. Two days before submission, her adviser asked why the reference had no page numbers. Maya checked the publisher page and found the article had moved from online-first status into a final issue six months earlier. The DOI was the same, but the citation had changed clothes. She updated the year, volume, issue, and article number, removed the advance online note, and added a comment in her draft: “Final metadata checked.” The fix took nine minutes. The lesson was not glamorous, but it was durable: before submission, search every early-online citation again. Some sources quietly mature while your manuscript is still learning to tie its shoes.
- Search by DOI again before submitting.
- Replace early-online notes with final issue details when available.
- Keep a short verification note for your own records.
Apply in 60 seconds: Search your document for “Advance online publication” and mark each occurrence for a final metadata check.
Common Mistakes That Make Good Sources Look Suspicious
Most citation errors are not dramatic. They are small. That is why they survive until the final reference list, where they sit in a neat row pretending to be respectable.
Here are the mistakes that create the most trouble in APA and Chicago reference repair.
Mistake 1: Leaving “Advance online publication” after final details appear
This tells the reader the source is not yet assigned to an issue, even when it is. In a student paper, it may look careless. In a manuscript, it may slow editorial cleanup.
Mistake 2: Treating database URLs as permanent links
Campus library URLs often include proxy strings or session data. They may work for you and fail for everyone else. Prefer the DOI when available. If no DOI exists, use a stable publisher URL when appropriate.
Mistake 3: Mixing DOI formats in one reference list
One reference says doi:10.0000/abc. Another says https://doi.org/10.0000/def. Another says DOI available at. This is not a reference list. It is a small formatting parade with no conductor.
Mistake 4: Trusting citation generators without field review
Citation tools can save time, but they cannot always infer publication status. They may put “advance online publication” in the wrong place, omit article numbers, or confuse journal issue data with page ranges.
Mistake 5: Citing the preprint when you used the final article
Preprints are valuable, but they are not automatically interchangeable with the peer-reviewed final version. If the final article exists and you used it, cite it. If you used the preprint because no final version was available, cite the preprint honestly.
Mistake 6: Copying page counts as page ranges
A PDF showing 12 pages is not the same as a journal page range. If the article uses e-locators or article numbers, follow the publication metadata, not the PDF viewer’s page count.
Risk scorecard: how urgent is the fix?
| Risk Level | Problem | Action |
|---|---|---|
| Low | DOI format is old but resolves correctly | Convert to current DOI URL style |
| Medium | Advance online note may be outdated | Check publisher final metadata |
| High | DOI points to a different title or author set | Stop and verify source identity |
| Critical | Article may be retracted, corrected, or not the version used | Ask a librarian, editor, adviser, or journal office |
Cleaning Zotero, EndNote, Mendeley, and Citation Exports
Reference managers are excellent servants and unreliable monarchs. Let them gather, store, and format. Do not let them rule without inspection.
The most common problem is not the software itself. It is dirty metadata. Library databases, publisher pages, and indexing services may export incomplete fields. Your reference manager then turns those fields into a citation with theatrical confidence.
Fields to inspect manually
- Item type: Journal article, preprint, report, book chapter, or webpage?
- Publication title: Full journal title, not abbreviated unless your style requires it.
- Date: Online date, final issue year, or posted date?
- Volume and issue: Present only if truly assigned.
- Pages or article number: Use what the publisher provides.
- DOI: Store only the DOI string or the expected field format for your manager.
- URL: Avoid duplicating DOI and URL unless your style or source type requires both.
Cleanup checklist before export
Reference Manager Cleanup Checklist
- Merge duplicate records before inserting citations into the draft.
- Open every item marked “online first,” “early view,” or “advance online.”
- Check whether final volume, issue, page, or article number has appeared.
- Move DOIs out of URL fields if your manager imported them incorrectly.
- Remove database session URLs and campus proxy links from public-facing references.
- Refresh metadata only after backing up important manual edits.
I once cleaned a Zotero library where one article existed three times: preprint, accepted manuscript, and final article. The paper cited all three in different chapters. No one had meant to create a scholarly hall of mirrors. It just happened one rushed import at a time.
Working with Zotero specifically
Zotero is powerful for DOI lookups and metadata cleanup, but you still need to inspect records. If a DOI lookup brings in incomplete fields, compare against the publisher page. If a PDF import creates a thin record, use title search or DOI search to enrich it.
For deeper citation-library habits, the guide on Zotero workflow improvements pairs well with this DOI repair process.
Working with EndNote and Mendeley
EndNote users should watch journal title lists and output styles. Mendeley users should inspect imported metadata from PDFs. Both tools can produce clean APA and Chicago references when the underlying record is clean.
The boring truth is also the useful truth: reference managers reward disciplined fields. Treat each record like a tiny drawer. Put the DOI in the DOI drawer. Put the URL in the URL drawer. Do not store a stapler in the sock drawer and blame the furniture.
- Clean item type before checking punctuation.
- Verify online-first records before final export.
- Keep DOI, URL, article number, and page data in the right places.
Apply in 60 seconds: Sort your library by date added and inspect the newest 10 records before writing more.
Make Your Citations Editor- and Reviewer-Ready
Editors and reviewers do not expect perfection from the first draft, but they do notice avoidable citation disorder. A reference list with broken DOIs, inconsistent online-first notes, and mismatched metadata creates friction. Friction makes readers doubt the care behind the argument.
This is not about performing scholarship with white gloves and a monocle. It is about making your evidence easy to verify.
Before submission, run a final citation pass
Use a focused pass rather than checking citations while also rewriting paragraphs, adjusting tables, and wondering why your coffee tastes like printer toner. Citation checking works best when it has its own lane.
- Search the manuscript for “doi,” “Advance online publication,” “published online,” and “ahead of print.”
- Verify each DOI link.
- Check each early online article for final issue details.
- Confirm every in-text citation has a matching reference entry.
- Confirm every reference entry is cited in the text.
- Run the reference manager refresh only after saving a backup copy.
Quote-prep list for asking a librarian or editor
When you ask for help, make the question easy to answer. Include:
- The full current citation
- The DOI you tested
- The publisher page URL
- The PDF first page if allowed
- Your required style, such as APA 7 or Chicago author-date
- Your deadline and submission context
A good help request is not “Citation broken, help.” A good request is “This DOI resolves to the right article, but the publisher page now shows final issue details. Should I remove the advance online publication note for APA 7?” That is a beautiful little question. It has shoes on.
Use respected style guidance
APA’s official style guidance is the first stop for APA reference questions. The Chicago Manual of Style is the natural stop for Chicago questions, especially when your instructor or publisher follows it closely. Crossref can help verify DOI metadata, though it is not a style manual.
Manuscript team workflow
If several authors touch the same reference list, assign one person to perform the final DOI and version check. Shared citation editing without a final owner can become a potluck where everyone brings commas.
For coauthored projects, connect the citation cleanup plan with your contributor agreement checklist. It sounds administrative, but clear ownership prevents last-minute reference chaos.
When to Seek Help Before Submitting
Most broken DOI and early-online citation issues can be fixed by careful checking. But some cases deserve another set of trained eyes.
Seek help when citation uncertainty affects academic integrity, publication eligibility, legal rights, or research reliability. The goal is not to look helpless. The goal is to avoid confident errors with long half-lives.
Ask a librarian when
- The DOI does not resolve, but the article appears in databases.
- Two records have the same title and different DOIs.
- The source may be a preprint, accepted manuscript, or final article, and you cannot tell which.
- The article has a correction, expression of concern, or retraction notice.
- Your reference manager keeps importing the wrong metadata.
Ask your instructor or adviser when
- The assignment has a strict style preference.
- You used a preprint because the final article was unavailable.
- The final publication year differs from the online-first year.
- Your discipline treats early online articles in a specific way.
Ask the journal or editor when
- You are preparing a manuscript for submission.
- The journal has its own citation style based on APA, Chicago, AMA, Vancouver, or another format.
- The publisher requires DOI checks or reference linking.
- The article metadata changed during revision.
- Librarians are excellent DOI detectives.
- Editors know house style and submission expectations.
- Advisers can clarify disciplinary norms.
Apply in 60 seconds: Write one precise question with the DOI, article title, and style requirement included.
One more practical note: if the citation question is connected to copyright, self-archiving, or version sharing, do not guess from style rules alone. Citation format and reuse permission are cousins, not twins. For that side of the desk, your copyright and fair use checklist can help separate attribution from permission.
FAQ
How do I fix a broken DOI in APA 7?
First, remove extra punctuation, spaces, and old labels such as “doi:”. Then test the DOI as a URL using https://doi.org/ followed by the DOI string. If it resolves to the correct article, format it in APA as a DOI URL. If it fails, search by article title, compare publisher metadata, and verify whether the DOI was copied incorrectly.
Should APA references include “Advance online publication”?
Use “Advance online publication” in APA 7 when the journal article is available online but has not yet been assigned final volume, issue, page, or article-number details. Remove that phrase once final publication details exist. The phrase explains missing details; it is not needed after the citation becomes complete.
How do I cite an online-first journal article in Chicago style?
In Chicago style, identify the author, article title, journal title, online publication status or date, and DOI when available. The exact punctuation and order depend on whether you are using notes and bibliography or author-date style. If final issue details later appear, update the citation to the final journal article format.
What if the DOI works but the citation generator gives different information?
Trust verified publisher metadata over a raw citation-generator output. Citation generators depend on imported fields, and those fields can be incomplete or stale. Compare the title, authors, journal, year, volume, issue, page range or article number, and DOI before deciding which record is correct.
Do I use the online publication date or final issue date?
Use the date appropriate to the version you are citing and the style rules you must follow. If the article now has a final version of record, update the citation to the final metadata. If only an online-first version exists, use the available online publication information according to APA or Chicago rules.
What is the difference between a DOI and a URL?
A DOI is a persistent identifier assigned to a digital object, such as a journal article. A URL is a web address. In modern citation practice, a DOI is often displayed as a URL beginning with https://doi.org/. A regular URL may change, while a DOI is designed to keep routing readers to the object’s current location.
Can I cite a preprint instead of the final article?
Yes, if the preprint is the version you used and it is appropriate for your assignment, field, or journal. But do not cite the preprint as though it were the peer-reviewed final article. If the final article exists and you rely on that version, cite the final version instead.
Why does my reference manager keep producing bad DOI citations?
Your reference manager may be using incomplete or incorrectly mapped metadata. Check the item type, DOI field, URL field, publication title, date, volume, issue, pages, and article number. Cleaning those fields usually fixes the output more effectively than repeatedly changing citation styles.
Should I include both a DOI and a URL in APA or Chicago?
For many journal articles, the DOI is enough when available. APA generally prefers the DOI in URL form for works with DOIs. Chicago practice may vary by notes-bibliography, author-date, and house style. If a source has no DOI, a stable publisher URL may be appropriate.
What should I do if two DOIs appear for the same article?
Do not choose randomly. Compare both DOI records against the publisher page, article title, author list, journal, and publication status. Sometimes one DOI belongs to a preprint, correction, accepted manuscript, dataset, or companion item. If uncertainty remains, ask a librarian or editor before submitting.
Conclusion: Turn the Citation Gremlin Into a Checklist
The broken DOI that looked like a scholarly disaster at the beginning is usually not a disaster. It is a small signal asking for order. Clean the DOI. Test the resolver. Compare the publisher record. Identify whether the article is a preprint, accepted manuscript, advance online publication, or final version of record. Then apply APA or Chicago style.
The concrete next step: in the next 15 minutes, search your draft for “doi,” “Advance online publication,” and “published online.” Pick five references. Verify their DOI links and final publication status. That small pass can prevent the kind of reference-list trouble that waits quietly until submission day, wearing a tiny villain cape.
