Harvard referencing has two halves that must match exactly. The in-text citation is the short marker inside your paragraph that tells the reader whose idea you are using. The reference list at the end gives the full details so that reader can find the source. If a name appears in one place but not the other, or the year or spelling differs between them, your marker will notice. This guide explains the rules for the in-text half in detail and shows how the reference list ties everything together. While you are drafting, the free Harvard referencing generator can help you build the full reference list entries so your in-text citations have something accurate to match.
Remember that many universities adapt Harvard slightly. The core rules below are shared by most UK versions, but punctuation and the exact use of “et al.” can vary, so treat your own university guide as the final authority.
Citing one author
With one author you have two equally correct ways to cite, and good writing uses a mix of both. In a parenthetical citation, both the surname and year sit in brackets at the end of the point: (Cottrell, 2019). In a narrative citation, the author becomes part of your sentence: Cottrell (2019) argues that study skills can be taught and improved with practice.
Use the narrative form when the author or study itself is the focus of your point, for example when you compare researchers or describe a method. Use the parenthetical form when the idea matters more than who said it, which is typical in most of your paragraphs. Do not include initials in in-text citations unless you need them to distinguish between two authors with the same surname who published in the same year.
Two authors, three authors and et al.
For two authors, name both surnames every time you cite. In brackets, connect them with “and” in most UK Harvard versions: (Bryman and Bell, 2019). In a sentence, do the same: Bryman and Bell (2019) distinguish between research design and research methods.
For three or more authors, most UK Harvard guides shorten the citation to the first author followed by “et al.”, which is Latin for “and others”. For example: (Saunders et al., 2023). Some university versions still ask you to list three authors in full on the first citation and shorten later citations only, so this is a detail worth checking. Whichever version you follow, the full reference list entry must name all the authors in full. “Et al.” is never used in the reference list itself.
Note the punctuation: there is a full stop after “al.” because it is an abbreviation, but no full stop after “et”. Writing “et. al.” is a common small error. Also, “et al.” is not italicised in most UK guides, despite being Latin.
Direct quotes and page numbers
Paraphrasing, where you restate an idea in your own words and sentence structure, needs a citation but does not normally need a page number, although some tutors encourage one. A direct quote is different. When you copy the author’s exact words, put them in quotation marks and add the page number so the reader can find the exact passage.
Example: “Learning is not a spectator sport” (Biggs and Tang, 2011, p. 3).
For a short quote, work it into your own sentence. For a longer quote, typically more than two or three lines, many guides ask you to set it out as a separate indented paragraph without quotation marks, followed by the citation. Check your guide for the exact length threshold your university uses. Never change words inside a quote without showing it. Use square brackets for any word you alter or add for clarity, and use three dots to show where you have cut words out. If the original contains a spelling error you want to keep, that is usually marked with [sic], but in most undergraduate work it is simpler to paraphrase instead.
Page numbers use “p.” for a single page and “pp.” for a range, for example p. 45 or pp. 45-47. If your source is a webpage or an ebook without stable page numbers, you may not be able to give one. In that case, some guides accept a paragraph number or a section heading instead. Do not invent a page number from a PDF viewer if it does not match the published pagination.
Citing the same source again, and secondary citations
You need to cite every time you use a source, even if you cited it in the previous paragraph. There is no rule that one citation covers a whole section. If you refer to the same source several times in one paragraph and it is completely clear which source each point comes from, one citation at the end of the paragraph is sometimes enough, but when in doubt, cite at each point. It is better to over-cite slightly than to leave a borrowed idea uncredited.
A secondary citation is when you cite a source that you have only read about inside another source. For example, you read a textbook that quotes an older study you have not seen yourself. The honest approach is to say so: (Freire, 1970, cited in Brookfield, 2017). Typically, only the source you actually read, Brookfield in this example, goes in your reference list. Use secondary citations sparingly. If the original work is central to your argument, try to find and read it directly through your library.
If the same author published two works in the same year that you use, distinguish them with letters: (Johnson, 2021a) and (Johnson, 2021b), and use the same letters in the reference list. The letter order usually follows the alphabetical order of the titles.
How the reference list works
The reference list is a single alphabetical list at the end of your work, ordered by author surname, then by year if you have used more than one work by the same author, earliest first. It is not split into sections for books, journals and websites in standard Harvard, and it is not ordered by the sequence in which you cited sources in the text. That numbered order belongs to other styles such as Vancouver.
Every in-text citation must have a matching full entry, and every entry should have been cited at least once. Before you submit, run a simple cross check: pick each name in your reference list and search your document for it, then do the reverse and search for each in-text name in the list. This five minute check catches most mismatches, including misspelled surnames and wrong years copied from an earlier draft.
For worked patterns for the full entries themselves, covering books, journals, websites and more, see our page of Harvard referencing examples, which shows each source type laid out in full.
Formatting of the list itself also matters. Many universities ask for a hanging indent, where the first line of each entry sits at the margin and later lines are indented, so surnames line up and are easy to scan. Leave a blank line or consistent spacing between entries if your guide asks for it, and keep the list on its own page if your assignment template requires that.
If referencing problems are part of a wider struggle with an assignment, perhaps the structure is not working or the deadline is close, our assignment help page sets out the support on offer, from £20 per 1,000 words. Fixing the argument first often makes the citations fall into place, because you become clearer about which source supports which point.
Citing several sources at the same point
Sometimes one claim rests on several studies. Put all the citations inside one set of brackets, separated by semicolons: (Smith, 2020; Jones and Roberts, 2021; Singh, 2024). Keep one consistent order, either chronological or alphabetical, throughout your work. This is how you show a marker that a point is widely supported rather than based on a single paper, and it is a habit markers associate with stronger, better-read essays.
When there is no page number
Not every source is paginated. For ebooks, web pages and audio-visual material, most guides accept another locator instead of a page: para. for a paragraph number, ch. for a chapter, a section heading in single quotation marks, a percentage or location marker for an ebook, or a timestamp for a video or podcast. Use the locator that lets your reader find the exact passage. Never invent a page number, and if you are summarising a whole work rather than a specific point, no locator is normally needed at all.
Frequently asked questions
Do paraphrases need a page number? Practice varies. Some universities require one for paraphrases as well as quotes, others only encourage it. A page number always helps your marker check a specific point quickly, so include one where you can.
Where does the citation go in the sentence? Usually directly after the idea it supports, and before the full stop that ends the sentence.
What if I cannot find an author? Use the organisation that published the source. If there is no organisation either, use the title of the work in place of the author, in both the citation and the reference list.
Do in-text citations count towards my word count? In most UK universities, yes, the citations inside your text are counted even though the reference list at the end is not.
Try it free
Practise the matching process on your current draft. Choose three citations from your own work, one with a single author, one with several authors and one direct quote, and rebuild their full entries using the free Harvard referencing generator. Then compare the spelling, year and punctuation in both places and correct any mismatch. Once that habit becomes routine, Harvard stops feeling like a separate chore at the end and becomes part of how you write from the start.
