Classify the source before copying any punctuation
Standalone webpage
Enter the author, published date or n.d., page title, site name, and complete URL. Add a retrieval date only for unarchived content designed to change; a footer copyright year is not automatically the page's publication date.
Standard journal article
Supply the article title, journal name, volume, optional issue, page range or article number, and DOI or stable URL when applicable. A repository page, abstract record, preprint, and accepted manuscript may require a different APA example than the published-article template.
Authored book
Provide author, year, book title, publisher, optional later-edition number, and DOI or URL when relevant. Edited volumes, chapters, translated works, reports, dissertations, and reference entries are outside this version's three templates.
Treat the source itself as the metadata authority
- Confirm authors and their order
Copy the byline order exactly. Enter each person as family name plus given names so the formatter can derive initials, or use the unabbreviated organization when the organization is the author.
- Verify date and title
Preserve proper nouns, acronyms, and trademarks while supplying APA sentence case yourself. Automated case conversion cannot reliably distinguish ordinary words from names, and this tool intentionally preserves the entered title.
- Check the source element
Compare journal, volume, issue, pages, publisher, site name, and identifier with the work's landing page or version of record. A syntactically neat reference can still identify the wrong edition or article.
Normalize a DOI without pretending to retrieve its record
For the supported journal and book fields, the formatter can turn a DOI label or legacy doi.org resolver form into an HTTPS https://doi.org/ link. The DOI Foundation describes the resolver as a way to redirect a persistent DOI name to current information about its referent. Normalization here is only string handling: the calculator does not contact Crossref, a publisher, or a DOI registration agency to confirm that the DOI exists or belongs to the work entered.
Follow APA's DOI and URL guidance for whether an identifier belongs in the reference. Do not append both a DOI and an arbitrary database session URL. Resolve the final DOI link yourself and inspect the landing-page title, authors, and publication details before submission; a successful redirect is useful evidence, but it does not repair other metadata fields automatically.
Audit the generated reference and its in-text forms separately
- Compare element order, punctuation, italics, and the hanging indent with the matching official APA reference example. Plain-text copying cannot carry every visual style cue into every destination.
- Review author-count treatment carefully. The bounded formatter lists through 20 authors and applies the first-19, ellipsis, final-author pattern for 21 or more, but unusual names and collective authors still deserve manual inspection.
- Check narrative and parenthetical citations in the actual sentence. Page or paragraph locators for quotations, repeated citations, multiple works, ambiguous author-year combinations, and secondary citations require context beyond the basic forms shown.
- Reject the template when a title needs mixed styling, such as an italic scientific name, superscript, or subscript. This version escapes user HTML and cannot safely encode partial typography inside a title.
Keep citation formatting distinct from evidence reporting
A reference tells readers what work is being cited; it does not demonstrate that a study was designed, analyzed, or reported adequately. APA's Journal Article Reporting Standards address what authors should disclose about quantitative, qualitative, and mixed-methods research. When checking descriptive results before writing, the statistics calculator can summarize a declared dataset, the z-score calculator can standardize an observation after a defensible mean and spread are established, and the standard deviation calculator can audit spread. Those computations still require appropriate methods, units, sample definitions, and reporting context.
Finally, compare the finished reference list with the citations in the manuscript in both directions. Every cited work should have the intended reference, and every listed reference should be used. Follow an instructor, journal, or institution's required variant when it narrows or supplements APA Style, and consult a librarian or style editor for archival materials, datasets, legal references, audiovisual works, software, social media, or other unsupported sources.
