Referencing guide at the University of Manchester: Harvard Manchester Updated

Disclaimer

The information contained within these pages is intended as a general referencing guideline.

Please check with your supervisor to ensure that you are following the specific guidelines required by your school.

General Rules for Harvard Manchester style

There are a variety of different referencing styles used across the University (Harvard, Vancouver, MHRA), so you should always check with your supervisor that this method of citation is accepted within your School. It is also vital that you remain consistent with your referencing style throughout your document.

Citations you include in the main body of your writing provide brief details of the work you are referring to. In the Harvard style, you place the relevant source information in brackets after a quote or a paraphrase. These short 'parenthetical' in-text citations' then link to a fully detailed reference, which you should include in your works cited (reference) list. You should also check with the person assessing your work whether parenthetical citations need to be included in your final word count.

The format of the parenthetical citation will depend upon a several factors. These include the nature of the source (print, DVD, web etc), and on the format of the source’s entry in your reference list. The signal word or phrase you provide to your readers in the text (which will usually be the author’s surname or organisation’s name), must be the first thing that appears on the corresponding entry in your reference list.

The Harvard style allows you to phrase your text so that credit is given to the author’s view (direct citation) or you can cite the author and page number after the relevant section (indirect citation).

General Harvard rules:

  • Author(s), up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘et al.’
  • Year in parenthesis followed by full stop.
  • The title is italicised when it is a sole entry and not part of something else.
  • The title is encapsulated in single quotations marks when it is a part of something else (chapter of a book or journal article) and the Book or Journal is italicised.
  • Reference type in [square brackets] when describing a web/digital platform such as Twitter and Instagram.
  • Pages have the phrase p. for one page and pp. for a page range.
  • Full stop after page numbers.
  • Full stop at end of reference.

Citation order

Citations supporting the same point to appear in chronological order (earliest first) then alphabetical on first author surname (for same year), separated by semi colons.

Author details

Citations:

Display author surname only.

If two authors separate author surnames with ‘and’.

If three authors separate author one and two with a comma, two and three with ‘and’.

Reference list

Display surname and initial(s). 

If three or fewer authors list all authors, separated with commas, with penultimate and last author separated with ‘and’. 

If four or more authors list first author and abbreviate with ‘et al.’ 

Casing (upper and lower case)

Author and title text to appear in sentence casing.
When using sentence casing, capitalise the first letter of the first word in the title. The rest of the words and letters in the title should not be capitalised, unless they're proper nouns.

Common elements for inclusion

A reference list is a crucial component. It provides the reader with information about the sources you used in your research and gives credit to the original authors. Your references will usually comprise of a mixture of printed and electronic sources. While some elements will appear commonly in both types of reference, others maybe be specific to one kind or another. The specific format and style of references may vary depending on the referencing style you are using (e.g., Harvard Manchester, APA, Vancouver, Chicago). When creating references for a piece of work, make sure you consider the following elements for the resource type: 

Common elements

Author(s)

List the names of the individuals or organization responsible for creating the content. Include the author's full name (or names) if available or use the username or screen name for social media sources. 

Year

The year of publication or the date the content was created or last updated.

Title

Include the title of the specific work being referenced, such as the title of an article, webpage, book chapter, or online document.

Issue information 

Volume/Part (when available) for journal articles. 

Page range

If you are referencing a specific chapter in a book or an article from a journal (printed or electronic), include the page numbers where the relevant content can be found. 

Print elements

Edition (if applicable)

If the source is a specific edition of a book or a version of a document, include the edition number. 

Publisher

For books, include the name of the publisher. For academic journals, include the journal's name. 

Publication location

For books, include the city and state (if applicable) where the book was published. For academic journals, this is not necessary. 

Electronic elements

Digital Object Identifier (DOI) or Uniform Resource Locator (URL)

When referencing online sources, include either the DOI (preferred for academic articles) or the URL where the source can be accessed.

Access Date (for online sources)

For online sources, especially webpages, include the date you accessed the source to indicate its availability. 

Format (optional)

For electronic sources that may not fit into standard categories (e.g., podcasts, videos, online presentations), indicate the format of the source (e.g., MP3, video file, PowerPoint presentation). 

Database or repository (optional)

Database or repository (optional): If the source is accessed through a specific database or digital repository, you may include this information. 

 

Remember to follow the guidelines of the specific citation style you are using carefully, as the format and order of elements may differ. Consistency and accuracy are crucial when creating your reference list to give proper credit to the original authors and sources you've used in your work. Always double-check your references to ensure they are complete and correctly formatted.

Harvard Manchester Style for EndNote

The Library has created the ‘Harvard Manchester’ style as an alternative to the default EndNote ‘Harvard’ style. The Harvard Manchester style displays author names in the reference list or bibliography in normal case rather than uppercase as used in the ‘Harvard’ style.

The Harvard referencing system is a convention specifying the order and content of references, not the way the references are formatted.  The most important factor with all referencing styles is to be consistent. You should contact your tutor or supervisor for details of any particular formatting specifications which may apply in your School.

If you do not have the Harvard Manchester style, you can download it below and follow these instructions to add it to your copy of EndNote.

To add the style to your EndNote Style list: 

  1. Have your EndNote (app) programme open
  2. Click on the link to download the Harvard Manchester style
  3. Open the downloaded style by double clicking on it
  4. Check the version in the section About this Style
  5. To save select File > Save As and choose the style name
  6. Select Save
  7. It will now be added to your list of available styles for you to select

Author of a chapter within an edited text

If the author’s work appears as a chapter within part of a larger work that is edited by somebody else (quite common with academic textbooks), use the author of the chapter for the citation within your text. You will however, need to provide the full bibliographic details in your works cited list (See section above: Chapter from an edited book for further details).

In-text citation

Lane (1996) argues that there are distinctive national patterns in the organisation of firms and inter-firm relations.

Authors & editors - citations

In-text citations

In-text citations consist of the surname(s) of the author(s) and the year of publication. 

Where the author(s) is mentioned in the text the citation consists of the year of publication in parentheses. 

Boatright (2008) argues that there are six questions that need consideration, before making a decision on whether to blow the whistle in a case. 

Where the author(s) is not mentioned in the text the citation consists of the surname(s) of the author(s) and the year of publication in parentheses, separated by a comma. 

There are six distinctive conditions, which need to be satisfied, in order for a whistle-blowing case to be justified (Boatright, 2008). 

No author: If you cannot identify the author of a document use the title of the work italicised. 

(One Thousand and One Nights, 1224) 

One author: the surname of the author and the year of publication are stated as below.

If the author title is quite lengthy you may want to spell out the name so that you can initialise it later in your work. 

Authors & editors - reference list

If two or more authors have the same surname then you need to provide more information to identify the source from which a quotation is taken. You should provide both author’s first initials (or even the authors' full name if different authors share initials) in your citation.

Reference list

This is usually dependant on the flow of your assignment, here are two examples:

Hollensen (2017) and Palmer (2018) are in agreement about the importance of service-led marketing.

Service led marketing should form an important part of an organisation’s overall marketing strategy (Hollensen, 2017; Palmer, 2018).

NB: Chronological order (earliest date first) of year before surname, if the same year then revert to alphabetical order.

Authors with the same surname

If two or more authors have the same surname then you need to provide more information to identify the source from which a quotation is taken. You should provide both author’s first initials (or even the authors' full name if different authors share initials) in your citation.

In-text citations

Same surnamed author in different years

(A. Hirst, 2015; J. Hirst, 2010)

Same surnamed same year

(A. Hirst, 2015; J. Hirst, 2015)

Same surnamed same initial

(Aaron Hirst, 2015; Alan Hirst, 2016)

Citing sources from another source

When you wish to refer to a source that is cited or quoted in another authors work then you need to acknowledge this. This is known as indirect or secondary referencing.

Use the term 'cited in' or 'quoted in' within your work. 

Nota bene: it is always preferable to cite the original source when possible.

In-text citations

Vampirism is described as ‘an epidemical disease of the brain, as dangerous and infectious as the madness of dogs’ (Tournefort, 1702 cited in Aquilina, 2013).

Corporate authors

If the work is by a recognised organisation, and has no personal author, then use the organisation’s name for the citation.

If the name is well known then initials are acceptable. e.g. (BBC, 2018).

If the author title is quite lengthy you may want to spell out the name so that you can initialise it later in your work.

In-text citation

In 1963 the United Nations Economic Commission for Africa predicted that Africa would evolve into an advanced industrial economy within fifty years (UNECA, 1963).

Making changes to quotations

To omit part of a quotation use an ellipsis (...).

In-text quotations

'Consider the three major social networks … none of these was profitable at the time of writing' (Chaffey, 2007, pp. 79-80).

You can insert your own words into the quotation by putting them in square brackets.

Jones notes that 'in these areas the larger [tobacco] companies often act the most irresponsibly' (2005).

If the original quotation contains errors (e.g. a spelling mistake) do not correct it. Instead point out the errors by writing [sic], The Latin adverb sic ('thus', 'just as'; in full: sic erat scriptum, 'thus was it written') e.g.

Williams (2008, p. 86) noted that ‘Johnson maid [sic] a mistake’.

Nota bene: Be consistent, you can use double or single quotations marks within your work, we suggest...

  • Use single quotation marks ('...') to indicate direct quotations and the definition of words.

  • Double quotation marks (“…”) are used for a quote within a quote.

  • Multiple works by a single author in the same year

    Citation order

    The Citation order would be those of the type of source the material is e.g. book or journal etc...If there are several works by one author (published in the same year) included in your Reference list entry, they should be differentiated by adding a lower case letter after the date.

    Setting out long quotations

    Longer quotations need to be entered as a separate paragraph and indented from the main text. You do not need to use quotation marks.

    In-text quotation

    Chaffey describes how it can be difficult to assess the success of e-businesses:

    Internet pureplay companies are often perceived as dynamic and successful owing to the rapid increase in visitors to sites, or sales, or due to initial valuations on stock markets. In reality, it is difficult to assess the success of these companies since despite positive indications in terms of sales or audience, the companies have often not been profitable. Consider the three major social networks: Bebo, Facebook or MySpace – none of these was profitable at the time of writing. (Chaffey, 2007, pp. 79-80).

    Setting out short quotations

    Any quotations used should be relevant to the argument you are making. Short quotations (4 or fewer lines of prose or 3 of verse) can be set in quotation marks and included within the body of the text.

    Enclose the quotation within single quotation marks, and then provide the author and specific page citation (in the case of verse, provide line numbers) in the text, and include a complete reference in the reference list. Punctuation marks such as commas, and semi-colons should appear after the parenthetical citation. Question marks and exclamation should appear within the quotation marks if they are a part of the quoted passage, but after the parenthetical citation if they are a part of your text.

    In-text citation

    The high burn-rate facing Boo.com was due to an 'imbalance between promotion and site development costs and revenues' (Chaffey, 2007, pp. 79-80).
