Harvard referencing refers to the general citation style of listing a source’s author and date in parentheses within the text, with a corresponding entry in a reference list at the end of the work.
If a customer says they’ve been asked to use the Harvard referencing style, it could be one of many variations. You should check if a particular version has been specified. If there isn’t, use this guide to apply the version we use, but add a note for the customer to check with their institution. Also, pay attention to the requested dialect. Quotation marks, for instance, will vary depending on whether the citation is written in US or UK English .
Essentially, the surname of the author of the source and the year of its publication must be given in the text. If it is not known when a source was published, it must be indicated with “no date” (abbreviated to “n.d.” ) in place of the year.
If a direct quote is made from a source, then the in-text citation must also include the page number (or paragraph) of the quote. For page numbers, the basic form is “p.” for a single page and “pp.” for quotes spanning multiple pages. For paragraphs, use “para.” (e.g., for websites that don’t have pages); for long documents without page numbers, you can choose to include the section or chapter number or name (e.g., Smith, 1998, Section title, para. 3), but do check with your institution’s style guide.
Those key pieces of information are given in parentheses in the same font as the surrounding text and separated by commas. The bracketed citation should immediately follow the portion of the sentence that comes from the external source. If the author is mentioned in the sentence, then the bracketed citation (which will then just include the year of publication) will need to follow directly after the author’s name.
In-text citations can take three basic forms :
If the source doesn’t come from an author with a surname – a corporate body, for example – then the name of that organization takes the place of the surname:
These basic rules will need to be adapted to various circumstances, which we will discuss next.
When there are multiple authors of the same work, the main thing to remember is that in-text citations name one or two authors. For three or more authors, only the first is mentioned, followed by “et al.” (in which case, note that a period is used in addition to a comma because “al.” is an abbreviation).
NB: When it comes to the full list of references at the end, all authors – some institutions put a cap on this, but others simply say to consult the course tutor – should be listed.
When both authors are named, the in-text citation will spell out “and” rather than use an ampersand (“&”).
An exception to only giving the surname of the author is if there are authors with the same surname and publications from the same year. In that case, the author’s initials should be added for clarity . Whether that initial comes before or after the surname, and whether or not it should have a period, will depend upon the university’s style guide. Our general approach is to put a period after an initial, as you would in any writing, but you should go for consistency within the document and flag the issue with a comment.
More frequently, you may come across citations for more than one work by the same author. If they were from different years but cited together, there is no need for the author’s name to be repeated. The years of publication are then listed in reverse chronological order (i.e., the newest comes first) with the years separated by semicolons . Each individual source is then listed in the reference list.
NB: When it comes to the full list of references at the end, the order of sources by the same author is chronological (i.e., with the earliest first).
If, however, the author has multiple works from the same year, a lowercase letter should be added to the year to differentiate the sources. The lettering should be alphabetical in the order that the sources are cited in the text .
NB: The crucial thing to check here is that the same system is reflected in the reference list at the end.
Multiple works by the same author in the same citation | There are a couple of sources that cover this (Woodhouse, 2022; 2020). |
Different works with the same author and date | This was a productive year (Woodhouse, 2022a), as can be seen here (Woodhouse, 2022b). |
If there is more than one source cited in support of a statement (e.g., multiple works by the same author), they will need to be cited in reverse chronological order and separated by semicolons . If the list includes works from the same year , they should be cited alphabetically by author .
NB: If the customer has consistently cited references in chronological order, then you should simply add a note for them to check whether this is what their university requires. Given the many variations on the Harvard theme, this could well be the case.
Multiple sources cited in support of the same point. | There are multiple sources that cover this (Woodhouse, 2022; Powell et al. 1971; Carter, 1940; A. Hopper, 1911; B. Hopper, 1911) |
You may see cases where the title of the source is given in place of the author. This is likely because the source has no named author (whether individual or corporate). In these cases, using the title of the source (the book, collection, etc.) is an acceptable variation, but it’s advisable to flag it with a comment to make sure.
If you’re presented with a reference to a work within a work (i.e., the customer hasn’t read the original but has come across it as a reference in another), this is a secondary citation.

The Harvard style requires a full list of all the sources that are cited within the text to be provided at the end of the document. The standard formatting requirement is to include it on a separate page titled Reference List .
Sometimes, a university will require a list of all the sources considered within a piece of work, even if they haven’t all been cited. This type of list is called a Bibliography .
In either case, the sources are listed alphabetically by the first item in the source’s full reference (usually the author’s surname). A corporate author or title of a work (if that comes first) starting with “The,” “A,” or “An” should be listed as if that word weren’t there (e.g., a source from the Open University would be listed under “O,” not “T”).
Detailing the sources in a reference list is probably the biggest cause of headaches for both writers and proofreaders. This is because the particular requirements differ depending on the type of source – and there are many .
The information itself is usually straightforward; it’s the formatting that gets tricky. In general terms, you could use the following as a checklist:
Item | Example |
---|---|
Author’s name: Surname first, then initial(s) after a comma, with a period after each initial. | Hopper, A. (1911). “This is my chapter,” in A. Name (ed.) This book. Kingston-Upon-Hull: Publisher, pp.30–45. |
Year of publication in parentheses, although this can vary between Harvard styles. | Hopper, A. (1911). “This is my chapter,” in A. Name (ed.) This book. Kingston-Upon-Hull: Publisher, pp.30–45. |
Title of any individual chapter (or similar) comes before the details of the main work. It is presented in quote marks and in sentence case; think of this as the warm-up to the main event. To separate this from the next piece of information, it is usually followed by a comma. | Hopper, A. (1911). “This is my chapter,” in A. Name (ed.) This book. Kingston-Upon-Hull: Publisher, pp.30–45. |
Title of the main work goes in sentence case (usually, although this can vary) and italics; think of this as stressing the importance of the main work. To separate this from the next piece of information, it is usually followed by a period. | Hopper, A. (1911). “This is my chapter,” in A. Name (ed.) This book. Kingston-Upon-Hull: Publisher, pp.30–45. |
If the source is not in hard copy/print form, the format is given in square brackets with a period after the closing bracket. | Hopper, B. (1911). “And this is my chapter,” in A. Name (ed). This other book [Online]. Available at https://allmadeup details.domain/yestotallymadeup/ (Accessed 1 April 2022). |
The place of publication appears before the name of the publisher, usually followed by a colon to separate it from the next piece of information. | Hopper, A. (1911). “This is my chapter,” in This book, Kingston-Upon-Hull: Publisher, pp.30–45. |
Publisher’s name comes after the place of publication. Think of the publisher as taking the important final credit. If further information does follow, there will need to be a comma in place. | Hopper, A. (1911). “This is my chapter,” in This book, Kingston-Upon-Hull: Publisher, pp.30–45. |
Any range of pages, URLs, and dates of access to online material come last. Make sure page ranges are formatted with an en dash (–) rather than a hyphen (-). | Hopper, A. (1911). “This is my chapter,” in This book, Kingston-Upon-Hull: Publisher, pp. 30–45. |
Let’s start with the most common types and see how those translate from in-text citations to full reference listings so that you can easily recognize them and, if necessary, fix them.
These sources are most likely to follow the general checklist given above. Within the list, “year of publication” is abbreviated to “year.” For particular issues relating to authors and years, please refer to the notes on in-text citations.
