APA reference guide
APA style cannot verify a source by itself.
Reference verification has two separate jobs: confirm that the source exists and matches the citation, then check that the verified metadata is expressed in APA style.

Identity before presentation
- Match the citation to a real record.
- Use metadata from the verified source.
- Apply APA rules to that confirmed metadata.
A two-pass APA check
1. Verify the work first
Confirm the title, authors, date, source and DOI against a publisher page or scholarly record before editing punctuation or italics.
2. Confirm author information
Check spelling, order and group authorship. Formatting initials correctly does not fix an incorrect author list.
3. Use the right date
Compare online publication and issue dates. Use the date appropriate to the version and source type you are citing.
4. Separate article and source titles
An article title and journal title have different capitalization and styling rules, but both must first match the verified record.
5. Normalize the DOI
When a DOI is available, present it as a https://doi.org/ URL and make sure it resolves to the same work.
6. Review source-specific rules
Journal articles, books, chapters, reports and webpages require different elements. Identify the source type before applying a template.
Frequently asked questions
Can an APA checker prove that a source exists?
Only if it also compares the citation with an external bibliographic record. A formatting-only checker cannot verify existence.
Should every APA reference have a DOI?
No. Include a DOI when the source has one, but many valid source types do not.
Which should I fix first, metadata or formatting?
Fix the identity and metadata first. Then format the confirmed fields in APA style.
Primary sources
Two different error classes
A reference can identify the correct source but use imperfect APA style, or look perfectly formatted while pointing to the wrong or nonexistent source.
