Harvard

The Harvard style

The Harvard style is used in the social sciences, technology and natural sciences. Check which reference style your department recommends before you begin writing your paper.

Reference list in Harvard style

When writing a reference list in Harvard style:

  • Arrange the list alphabetically by author’s surname
  • Sort the Swedish letters ä - ö - å like you sort the Norwegian letters æ - ø - å
  • Start the reference list on a new page. Use “Reference list” or “Literature list” as the heading.
  • Include the edition if it is specified in the publication. You need not add the date of printing if this is just a reprint of the current edition. If it is the first edition, do not write the edition.
  • If a reference has more than 3 authors, only write the first author’s surname followed by “et al.”

Personal communication in Harvard style

In the Harvard style, personal communication should not be included in the reference list, if the information cannot be gathered again. Personal communications are conversations, e-mails, phone calls, etc. Remember to ask approval from the partner of the conversation before citing him/her.

You can cite personal communication in the text. You should include the name and title of your conversation partner, the date of communication and the context in which the communication took place.

The Harvard style in-text

When using the Harvard style in-text, you must remember:

  • If a reference has more than 3 authors, only write the first author’s surname followed by “et al.
  • Multiple publications by the same author published the same year are distinguished by a, b, c etc. after the year: Hansen (1988a) and Hansen (1988b).
  • If you refer to two or more publications at the same time, sort the publications in chronological order with the earliest first. Example: (Hansen, 1988a; Olsen, 2001)
  • When a work has no identifiable author, use the title. Example: (Et enklere og mer rettferdig inntektssystem, 1996)
  • When a work has no identifiable release date, use no date. Example: (Trondheim kunstmuseum, no date).
  • When using secondary sources, name your source and cite the secondary reference. Example: Johnson and Peters’ studies (1970, as cited in Wagner, 1982)…
  • Use page numbers when:
    • it is a direct quote
    • if you use ideas from a specific page/specific pages in a work
  • When quoting a web page, use the paragraph number to help the reader locate where in the text the quote is from. Example: (Fuglesnes, 2004, para. 4).

References

Example: Researchers such as Warwick (1992), Taylor and Smith (1994) and King et al. (1997) found that…

Quotations

Direct quotations shorter than 2-3 lines are integrated in the text and are clearly marked with quotes. Quotations longer than 2-3 lines should be in a separate indented paragraph, without quotes.

Eksempel - sitat

Short quotation:

“Sitering vil si ordrett gjengivelse av andres arbeider. Da skal det være ordrett, og ikke misbrukt i forhold til den sammenheng sitatet brukes i” (Stene, 1999, p. 125).

The name of the author is integrated in the paragraph:

Stene (1999, p. 125) defines quoting as: “Sitering vil si ordrett gjengivelse av andres arbeider. Da skal det være ordrett, og ikke misbrukt i forhold til den sammenhengen sitatet brukes i”.

Source with many authors:

“Ved direkte sitater skal henvisningen gi informasjon om forfatter, årstall og sidetall” (Furseth and Everett, 1997, p. 141).

Mer om Harvard

Indirect quotations - paraphrases

A paraphrase is a reformulation of the original text.

Eksempel - Indirekte sitater

Example

Furseth and Everett (1997) maintain that the primary reason behind the use of references and bibliographies is the ideal of research as a collective endeavour. Research should be verifiable, and those reading your work should be able to find those sources your material is based upon.

More on the Harvard style

There is no official manual for the Harvard style. Information on how you write references in-text and in a reference list with the Harvard style is based on Pears and Shields (2016).
