Referencing guide: Harvard Bath

There are many different versions of "Harvard" referencing. This guide is the University of Bath Library’s interpretation, based on BS (1989) and ISO (1990) standards, and adapted in line with local preferences. If you are uncertain whether you should use Harvard (Bath), check with your department. We also provide a short PDF version of the guide, as well as the full guide PDF.

There are standard reference formats for most types of document. Below are examples of the most common types of document you might want to reference. Each of the following gives a suggested standard format for the reference followed by examples for the different document types.

Pre-publication e-journal article

You may find an electronic version of a journal article before it is in its final, published version in print. These can still be cited and referenced. As they will not yet have the volume, issue and page range details, that information can be omitted from the e-journal article reference. Instead, immediately following the ‘Journal title [Online],’ you can insert one of the following terms (appropriate to the stage the article is at in the publishing process):

  • ‘preprint’ – an author’s original draft of the article that they have distributed prior to peer-review and publication
  • ‘in press’ –  a publisher’s accepted, peer-reviewed, pre-publication version on its website or the author’s accepted and edited manuscript in their institutional repository (prior to the official publication date)

These templates are primarily for sources used in print. If you have accessed an online version, you can adapt the format by adding the following to the reference: after the source title or equivalent, you can add [Online], whilst at the end of the reference add Available from: the web address (URL), and the [date you accessed the document]. For an example, see the Statutory instrument (online) template below. For further guidance on online documents, click on to the 'Write a Reference' tab at the top of this table.

Work in translation

When referencing a work that you have read in translation, cite the original author and acknowledge the version you have read in your reference.

Author(s) Surname, INITIALS, Date. Title (Name of translator, Trans.). Place of publication: Publisher.

Aristotle, 2007. Nicomachean ethics (W.D. Ross, Trans.). Sioux Falls, S.D.: NuVisions.

Work in the Roman alphabet

Use the standard format for the type of literature (e.g. books, journal articles). Give the title of the work in the original language, and add the translated title in square brackets after it. Giving the translation simply helps the reader understand what the work is about. For a journal article, give a translation of the article title, but there’s no need to translate the journal title. 

Example for a book:

Esquivel, L., 2003. Como agua para chocolate [Like water for chocolate]. Barcelona: Debolsillo.

Example for a journal article:

Thurfjell, W., 1975. Vart har våran doktor tagit vägen? [Where has our doctor gone?]. Läkartidningen, 72, p.789.

Work in a non-Roman alphabet

Here we really need to think about things like enabling filing order in the manuscript and what would be helpful to the English-speaking reader.

For non-Roman-alphabet languages you may need to include both a translation and a transliteration. Chinese or Japanese characters, immediately following the romanised version of the item they represent, help readers identify references cited or terms used. 

For the author (or organisation), you definitely need to use a transliteration of the name into the Roman alphabet. This will allow you to have one single list of references/bibliography in alphabetical order. Use a consistent transliteration system (e.g. pinyin for Chinese names or romaji for Japanese names).

For journal articles and other sources, you have a choice of two options (bullet points below). Whichever you choose, be consistent and use it throughout your bibliography. 

  • The Author’s name is given in Roman characters first (to allow the reference to file properly in your bibliography) and then the name in original characters immediately afterwards. The article title and journal title are given in their original language (both transliterated and in the original characters) followed by an English translation in square brackets. The rest of the reference follows the standard format.
  • The author’s name in Roman characters; the title transliterated into Roman alphabet with a translation in square brackets. There is no need to translate the journal title, just transliterate it. The rest of the reference follows the standard format.


Hua, L.華林甫, 1999. Qingdai yilai Sanxia diqu shuihan zaihai de chubu yanjiu清代以來三峽地區水旱災害的初步硏 [A preliminary study of floods and droughts in the Three Gorges region since the Qing dynasty]. Zhongguo shehui kexue中國社會科學, 1, pp.168–79.


Hua, L., 1999. Qingdai yilai Sanxia diqu shuihan zaihai de chubu yanjiu [A preliminary study of floods and droughts in the Three Gorges region since the Qing dynasty]. Zhongguo shehui kexue, 1, pp.168–79.


Pamporov, A., 2006. Romskoto vsekidnevie v Balgariya [Roma everyday life in Bulgaria]. Veliko Tarnovo: Faber.


If you would like to include a quote from a work in non-Roman alphabet, then there are a few options to consider:

  • Include the quote in the original characters followed by the English translation in square brackets.
  • Include the quote in its transliterated form followed by the English translation in square brackets.
  • Paraphrase instead of quote.

Whichever option you choose, be consistent and use it throughout your work.  In all cases a citation and reference to the original work is required.

General guidelines

You need to be thorough and consistent when referencing source (for example, in the use of commas and italics). Otherwise, you may lose marks. ​

  • Authors: list every single author/editor of a source in your full reference and in the same order that they appear on the back of the title page. The same surname (or organisational name) that appears at the start of your citation should appear at the start of your reference. If you are unable to identify either an individual named author or an organisation, you should enter Anon. (short for anonymous) instead.
  • Editions of books: do not include an edition number if you have used a 1st edition of a book.
  • Titles: Use uppercase only for the first letter of the title and names (persons, organisations or places).
  • Subtitles: All of the subtitle, including the first letter, should be entered in lower case (with the exception of names). The subtitle should be entered after a colon. For example: Reflective reader: social work and mental health.
  • Year of publication: if this is not provided within the source, you should enter n.d. (short for no date) instead. If you entered a letter at the end of a publication year (e.g. 2000b) within your in-text citation, the same year+letter should appear in the reference. However, if you entered n.d. in your citation (because no year of publication is provided), n.d. should appear in your corresponding reference instead e.g. Taylor, n.d.
  • Publisher: enter the name of the publisher that published the specific edition/version that you are using. If a shortened name of a publisher appears on the title page, you can use this. For example, rather than John Wiley and Sons Inc., you could enter Wiley. If one of the following words appear within the publisher's name, don't include these in your reference: Ltd., Publisher or Publishing. If one of the following words appear, do include them: Press or Books. If you cannot identify a publisher, enter s.n. (short for sine nomine) instead.
  • Place of publication: if multiple places are listed, use the city or town that is listed first. Don't confuse a location of printing with a place of publication. USA-based publishers: after entering the name of the city/town, enter a comma followed by the abbreviated form of the state, for example Pa. = Pennsylvania. For more examples, please refer to standard USA state abbreviations.  If no place of publication is provided, enter the following: s.l. (short for sine loco).
  • Online documents: if you use a source that you found online, you may need to indicate this as follows:  
    • PDFs: if you are referencing a PDF which is a copy/equivalent of a print publication (with the same page numbers), your reference does not need to indicate that you found it online. For example, you do not need to include a web address or accessed date. However, if you are not sure about the PDF's origins, you need to use the format for other types of online document as outlined below.
    • Other types of online document (including PDFs and other sources that are not copies/equivalents of print publications): these are "online-only" sources and you need to indicate their online origins.  Some reference examples already indicate this (e.g. electronic book, electronic article, website).  However, you may need to adapt a format (e.g. adapt the 'report' format for an online-only report) by adding the following to the reference:  [Online]. Available from: the web address/URL [the date that you accessed the document].  Example of a reference to an online-only source: 
Haynes, W.M., ed., 2014. CRC handbook of chemistry and physics [Online]. 94th ed. Boca Raton, Fla.: CRC Press/Taylor and Francis. Available from: [Accessed 16 June 2016].

You need to be thorough and consistent when citing sources (for example, in the use of commas and italics). Otherwise, you may lose marks. 

1. If the author’s name occurs naturally within your writing, enter the surname and then enter the year in parentheses. 

Although first prepared by Benedikt (1879), it was not until much later that Osborn and Jay (1975) confirmed its structure. 

2. If the author’s name does NOT occur naturally within your writing, enter both the surname and year in parentheses. Note the use of the comma.  

Although it was first prepared in the later nineteenth century (Benedikt, 1879), its structure was not confirmed until much later (Osborn and Jay, 1975). 

3. Year of publication: this needs to be entered, where possible, when referencing any type of source (printed, online or software). With books, enter the date relevant to the edition of the book that you have used. If no date is provided by the source, enter n.d. (short for no date).

4. Page information/location: if you are quoting an author or citing an image/figure, always enter the relevant page number(s). It is also good practice to enter page numbers if you are citing a very specific piece of information that appears within a long document, such as a book. If you are entering a range of page numbers, enter pp. rather than p..

James and Williams (2003, p.75) have argued that...

No page numbers provided? Use the following within your citation:

  • Kindle ebooks: even where page numbers are provided, these can change when you resize your text, but you can use location numbers instead; for example: (Hodds, 2016, loc.1 of 4584). 
  • Webpages: you can identify the relevant paragraph from a webpage; for example: (Hodds, 2016, para.4). 

5. Two or three authors: cite both/all surnames in your text. 

Smith and Jamal (2010) have argued that…

6. Four or more authors: cite the first author’s/editor’s name, followed by et al., which is a notation meaning 'and others'. You will need to list all the authors in your reference list.

Case studies have been developed to support these claims (Andersen et al., 2004).

7. Citing multiple sources in a single citation (where they are making the same point): enter these in chronological order, starting with the earliest. For example: (Adams, 2005; Dass, 2012; Carter, 2015).  

If the multiple sources in a single citation are written by the same author, they would appear in the chronological order as follows: (Adams, 2009; 2014; 2017).

8. No individual person(s) as author: if the document is produced by an organisation, you can enter the organisation’s name as the author. If neither a person or an organisation can be identified, enter the title of the work where you would normally enter the author. If none of these alternative options are viable, enter Anon. (short for anonymous).  Please note that with some legal or government documents (including, for example, UK Acts of Parliament), you should always enter the title of the document as the author - for detailed information about this, refer to the 'Legal or government document' section in the Reference Examples A-Z in this guide.  

Statistics from a recent report (World water resources, 2011) indicated… 

This was recently discussed in a House of Commons paper (Great Britain. Parliament. House of Commons, 2004).

The law specifies that ... (Pensions Act, 2014).

9. Multiple documents by one author published in the same year: Add an ‘a’ at the end of the publication year for the first document that you cite. Then add a ‘b’ for the second document, and so on. The same letter should appear in the corresponding full reference.  

Tavernor’s initial review of Palladio’s work (2001a) is extended and examined in much more detail in his later work (2001b). 

10. Citing a document that has been cited in another document: where it has not been possible for you to read the original, then cite both in the text. However, in your list of references, you would only list the work that you actually read (in the example below, you would only reference the work by Jones). Also note the use of the commas and the semi-colon.

An early interpretation (Walters, 1883; cited by Jones, 1987, p.73) suggested...

11. Images (graphs, diagrams, designs, illustrations, photographs): refer to the Referencing Images guide.  

12. Personal communications: emails, letters, conversations and interviews are examples of unpublished personal communications. Interviews can include interviews that you have conducted yourself. You must cite all unpublished sources by providing the informant's name (if they are willing to give it, otherwise use Anon., short for anonymous) followed by (pers. comm.) and the date of the communication.

The Vice-Chancellor of one HE institution asserted that the recent rise in student numbers is having a detrimental effect on many aspects of university life, in particular forcing staff and students to attend teaching sessions after 6pm (Anon. (pers. comm.) 30 August 2006).

Note: If you make use of an email, letter, interview or conversation that has been published (e.g. on a public website or in a book/article), you should cite it as you would cite any published source of information.

  • Title of list: either Reference List or References is fine (unless your department has specified one or the other). If you have been asked to list other works that you have read but not used in your writing, then provide a separate list for these under the heading Bibliography. 
  • Be thorough: the list should include a full reference for each cited source from within your main text (unless the source is unpublished material).
  • List references alphabetically by the author’s surname or organisational name. The surname or organisational name that appears at the start of your reference should be the exactly the same as the one that appears at the start of your citation. 
  • Multiple sources by the same author(s): list them in chronological order, starting with the earliest publication date.  
  • Multiple sources by the same author(s) published in the same year: List your references to the author in year/alphabetical order (2000a, 2000b). The year and letter should correspond to the one that you entered in your main text (an 'a' is added for the first cited source, a 'b' is added for the second, and so on). 
  • Multiple sources by the same first author with different co-author(s): list them in alphabetical order by the second author. If the first and second co-authors are the same for multiple references, list them in alphabetical order by third author (and so on). For example, a work by Taylor, S., and Morris, A. (2014) would be listed before a work by Taylor, S. and Williams, A. (2011).
