OmniDocHarvard Citation Format: How to Reference Sources
Learn Harvard author-date citation, including in-text formats, reference list entries for books, journals and websites, and common mistakes to check.
Harvard referencing is one of a common citation styles in universities, and it is also one of the least consistent. A tutor may ask for "Harvard" without naming a guide, and two universities can publish slightly different rules for the same thing. If you are a student who has to format a citation harvard style for the first time, the result is often a mix of author names, years and punctuation that looks almost right but would lose marks.
This guide covers the core Harvard author-date system: how to write the in-text citation, how to build a reference list entry for the sources you use most, and how to check the finished work. The rules here apply to the general Harvard pattern. Where universities differ, the guide below says so, and your own department's handbook should win.
You will also see a few steps that involve a word processor. Because the same formatting carries over to a Word-compatible editor, the steps work whether you type in Word or in another editor that opens .docx files.
How do you format a citation in Harvard style? The short answer
Put the author's surname and the year in brackets in the text, then add a full entry for that source in an alphabetical list at the end of your work. The table below covers the situations students meet most often.
| Your situation | What to do | Why |
|---|---|---|
| You paraphrase an idea from one author | Write (Surname, Year) at the end of the sentence | The reader can find the full entry in the reference list |
| You quote the exact words | Add the page number, such as (Surname, Year, p. 45) | Direct quotes need a location as well as a source |
| The source has two authors | Write (Surname and Surname, Year) | "And" is used in the text instead of an ampersand |
| The source has three or more authors | Write (Surname et al., Year) in the text | Shortens the citation; the reference list may list all names up to a limit set by your guide |
| You cite a website with no date | Write (Surname, n.d.) | "n.d." means no date, which tells the reader the date is missing |
Before you start
Gather these details before you write any entry. Missing information is a common reason a Harvard reference looks wrong.
- Your university's guide. Many institutions publish their own Harvard handbook. Where it differs from the general pattern, follow it, because markers check against it.
- The details from the source itself. Take the author, title, year and publisher from the title page or article header. Search result summaries can show a different date or a shortened title.
- The edition number. A second or later edition is listed in the entry, so check the copyright page of any book you cite.
- The DOI or URL, and the access date for web pages. Online sources need a stable link, and web pages also need the date you last viewed them, because content can change.
- A plan for sorting. The reference list is alphabetical by the first author's surname, so keep a simple list while you research and sort it at the end.
Writing Harvard references, step by step
- Decide what kind of source each reference is. Books, journal articles, edited chapters, reports and web pages each use a different entry pattern, so sort your sources before you write anything.
- Write the in-text citation as you go. Place the surname and year where you use the idea, then add the page number if you quote directly. This avoids searching back through the text later.
- Build each reference entry in the order the guide specifies. The usual order is author, year in brackets, title, edition, place, publisher. Journal articles add the journal name, volume, issue and page range.
- Italicize book and journal titles, and put article titles in single quotation marks. If you type in the UniDoc web editor at app.unidoc.top, apply italics directly to the title text, as you would in any Word-compatible editor.
- Add the DOI as a full link for journal articles. Use the complete address starting with https, because a DOI written as a bare code is harder for markers to check.
- Add the access date to web entries. Write "Available at:" before the link and "(Accessed: day month year)" after it, using the date you viewed the page.
- Sort the reference list alphabetically by first author. When one author has several works, list them by year, oldest first. Use 2020a and 2020b if the same author has two works in one year.
- Compare the list with the text. Every in-text citation should match an entry, and every entry should be cited somewhere in the work.

- Journal article: Lindqvist, M. and Park, J. (2021) 'Measuring reading time in short essays', Journal of Applied Learning, 14(2), pp. 101-118. Available at the full DOI link. In text: (Lindqvist and Park, 2021).

Check the result
Once the work is complete, run through these checks. Most lost marks come from small inconsistencies rather than missing sources.
| Check | How to see it | If it's wrong |
|---|---|---|
| Every citation has an entry | Search the text for each surname and year and find its match in the list | Add the missing entry, or remove the citation if the source was not used |
| Every entry is cited | Go through the list and find one in-text citation for each | Cite the source where you use the idea, or drop it from the list |
| Years and spellings match | Compare each year and surname character by character | Correct the entry so both places use identical information |
| Italics and quotation marks are consistent | Scan titles: books and journals in italics, articles in single quotes | Reapply italics or quotes to the affected titles |
| Sorting is alphabetical | Read the surnames down the list in order | Move entries and re-check the order for same-author works |
If you used an online citation generator or a reference manager, still compare its output with your guide. These tools often leave out the edition, misplace the access date or use a different style variant.
❓ FAQ
1. Do I need page numbers for every citation?
No. Page numbers belong with direct quotes, and many guides also ask for them when you refer to a specific figure, table or passage. For general ideas taken from a whole book or article, the author and year are enough.
2. How do I cite a source that has no author?
Use the title in place of the author in the text, shortened if it is long, and start the reference entry with the title. Keep the year. If the organization that published the document is named on it, use that organization as the author instead.
3. Should I use "et al." in the reference list?
Usually not in the list itself. Many Harvard guides list up to three names in the reference entry and use "et al." in the text. Some guides differ, so check your university's handbook.
4. How do I cite a PDF I downloaded?
Treat it like the original source. If it is a journal article, use the journal entry format with the DOI if one is printed on the file. If it is a report, use the organization, year and title, and add the URL and access date if you read it online.
📝 Summary
Harvard referencing works well when you apply one pattern consistently: author and year in the text, a complete entry in an alphabetical reference list, and punctuation that follows your university's guide. Work through the checks before you submit, because small mismatches are the usual cause of lost marks. Use your institution's handbook as the final authority on any detail this article leaves open.
