Harvard Citation Checker
Paste your Harvard reference list and get each likely slip flagged: given names spelled out instead of initials, a year with no brackets round it, a quoted title in Title Case, a web address with no “Available at:” or access date, a missing final period, a list that mixes “and” with &, entries out of A–Z order, and repeated sources. Harvard varies by university, so every finding is advice, not a verdict. Free, no sign-up, and nothing leaves your browser.
What this checker looks for
- Authors abbreviated to initials — “Smith, J.” or “Smith, J.M.”, not “Smith, John”.
- The year in parentheses directly after the authors — “(2020)” — or “(no date)” for undated sources.
- Article and chapter titles in sentence case rather than Title Case.
- URLs cited as “Available at:” plus “[Accessed date]”.
- A terminal period (unless the entry ends in a URL or DOI).
- A consistent “and” or “&” connector, alphabetical order, and duplicate entries.
Every finding is advisory. Harvard is a family of styles, not one official standard — this checker targets the common Cite Them Right conventions, and your institution's guide always wins. The checker is deterministic — it never uploads your text, never uses AI, and never auto-rewrites your references.
How to Use the Harvard Citation Checker
- Paste your reference list. Put one reference per line, or separate wrapped references with a blank line. The checker joins wrapped lines into one reference.
- Read the list-level findings first. Mixed connectors, entries out of A–Z order and repeated sources affect the whole list, so they appear above the individual entries.
- Work through each flagged entry. A finding says what looks wrong, offers a corrected fragment to copy when it can, and links to Cite Them Right. High confidence means the pattern is almost always an error; Worth a look means it often is.
- Compare with your university’s guide. Harvard has no single official manual, so settle any disagreement in favour of the guide your department sets.
Which Harvard Does the Checker Follow?
Harvard is an author-date family of styles, not one standard, and universities publish their own variants. The checker follows the conventions taught in Cite Them Right (Pears and Shields), the guide most UK universities build on. Where a variant differs, such as using & instead of “and”, trust your own guide.
| Element | Form the checker expects | Flagged when |
|---|---|---|
| Author | Smith, J. — surname and initials | a full first name follows the comma, as in Smith, John |
| Year | (2020) straight after the authors, or (no date) | a year appears but not in brackets |
| Article title | ‘Sentence case in single quotes’ | every principal word in a quoted title starts with a capital |
| Web source | Available at: URL [Accessed 4 May 2026]. | a URL has no “Available at:” or no (Accessed: …) / [Accessed …] date |
| Ending | a period, even after [Accessed …] | the entry ends with no punctuation and no link |
| Connector | “and” (or & if your guide uses it) — one choice | the list uses both “and” and & |
| List order | A–Z by the first author’s surname | an entry sorts before the one above it |
| Duplicates | each source listed once | two entries share author, year and the start of the title |
Cite Them Right writes the access date in round brackets, as (Accessed: 4 May 2026); many university guides use square brackets instead. The checker accepts either form, but it does not check that the date is a real date or that it follows your guide’s format.
Worked Example
Choose Try a sample to load three invented references. The checker reports 6 likely issues to review across 3 entries, and every entry has something to fix:
- The list: the entries run Smith, Brown, Adams, so entries 2 and 3 are each flagged as out of A–Z order. It is one problem — the list is reversed.
- Entry 1 spells out Smith, John; the fix is Smith, J.
- Entry 2 uses the older style Brown, K.L. 2021. with no brackets; the checker suggests (2021).
- Entry 3 has a Title Case title, ‘Coastal Birds and Their Habitats’ (sentence case is ‘Coastal birds and their habitats’), and a bare web address with neither “Available at:” nor an access date.
What a Plain-Text Check Cannot See
- Formatting. Italics for book and journal titles and the hanging indent do not survive pasting. Add the indent with the Hanging Indent Formatter.
- Whether the details are true. A wrong volume, a dead link or a source that does not exist all pass.
- In-text citations. Only the reference list is read, not (Smith, 2020) in your text.
- Variant rules. Page-range dashes, how many authors are listed before et al., edition and place of publication are left to your guide.
Which Citation Checker Do You Need?
Harvard is the right choice when your instructions say “Harvard” or name a university variant. APA also uses author-date, but its rules differ in punctuation, so APA lists belong in the APA Citation Checker. If you are not sure which style a list uses, try the Citation Style Identifier.
| Your style | Use | Reference list is called |

| APA 7 | APA Citation Checker | References |
| MLA 9 | MLA Citation Checker | Works Cited |
| Chicago 18 | Chicago Citation Checker | Bibliography |
| Harvard | This page | Reference list |
| IEEE, Vancouver, AMA | IEEE, Vancouver or AMA checker | Numbered references |
Frequently Asked Questions
- What does a Harvard citation checker check?
- This one reads each reference for given names spelled out instead of initials, a year that is not in brackets, a quoted title in Title Case, a web address without “Available at:” or an access date, and a missing final period. It also checks that the list does not mix “and” with &, and flags entries out of A–Z order and repeated sources.
- Is there one official Harvard referencing style?
- No. Harvard is a family of author-date styles and each university sets its own details. The checker follows the common Cite Them Right conventions, and its findings are advice, so a rule in your department’s guide always overrides them.
- Should Harvard references use “and” or “&”?
- Cite Them Right uses “and”; some university variants use &. Either is acceptable if you use it throughout, which is why the checker flags only a list that mixes the two.
- How do you reference a website in Harvard style?
- Give the author or organization, the year in brackets, the page title, and then Available at: followed by the URL and the date you accessed it. Cite Them Right writes that date as (Accessed: 4 May 2026); many university guides write [Accessed 4 May 2026]. If there is no date use (no date). End the reference with a period.
- Should article titles be in sentence case in Harvard?
- In most Harvard guides, including Cite Them Right, yes: capitalize only the first word and proper nouns, and put the article title in single quotation marks. Book and journal titles are set in italics. The checker flags a quoted title only when all its longer principal words are capitalized.
- What is the difference between Harvard and APA?
- Both put the year in brackets after the author. Cite Them Right Harvard writes Smith, J. (2020) with no full stop after the year and puts article titles in single quotation marks; APA writes Smith, J. (2020). with a full stop, no quotation marks, and a DOI as an https link. See the Harvard vs APA guide.
- Is my reference list uploaded anywhere?
- No. The checker runs entirely in your browser; nothing you paste is sent to a server or stored.
