What is the Harvard style?

The Harvard style is a so‑called author–year citation style. This means that the source is named directly in the text – usually in round brackets – and not in a footnote. At the end of the paper, you include an alphabetically sorted reference list with all sources used.

The Harvard style is not a strictly standardised citation style. What matters is not one single “correct” form, but that you cite consistently and uniformly throughout your paper.

Short references in the text

In the Harvard style, you refer to your source directly in the text. A short reference consists of the author’s last name, the year of publication and – if needed – the page number.

(Müller 2021, p. 45)

In indirect quotes, you express ideas from a source in your own words. This form of citation is the norm in academic studies. A page number is recommended, especially when you refer to a specific passage.

Informal desire paths mainly emerge where the planned routing does not match the users’ actual movement patterns (cf. Müller 2021, p. 45).

You reproduce direct quotes verbatim from the source. They appear in quotation marks and must always be proved with a page number.

“Desire paths follow a collective optimisation logic.” (Müller 2021, p. 45)

Use direct quotes sparingly. In academic writing, indirect quotes are expected in most cases.

Multiple authors and special cases

• Two authors: (Müller & Schmidt 2020)
• Three or more authors: (Müller et al. 2019)
• Several sources in one reference: (Müller 2021; Schmidt 2019)

The reference list in Harvard style

In the reference list, you include all sources you have cited in the text – and only those. The entries are sorted alphabetically by the authors’ last names. Below you will find three examples of the most common types of sources.

The Harvard style can create uncertainty because several valid variants exist. It is therefore important to follow the guidelines provided by your lecturers or professors (if available) and remain consistent throughout your paper.

Tips for using the Harvard style

• Only include cited sources in the reference list – and follow the same structure for all entries.
• Special sources (social media, interviews, lectures) require adapted information such as platform, date or URL.
• Indent long direct quotes; for indirect quotes, you may optionally add “cf.” at the beginning.
• Write authors’ names exactly the same in the text and in the reference list.
• Zotero helps with collecting and formatting – but it does not replace your own content check.
• Common mistakes: missing page numbers in direct quotes, inconsistent spelling of names, incorrect use of “ibid.”.

Why Do I Have to Cite?

Why cite at all? To prove facts: You state where your information comes from, ideally tracing it back to the original source. This not only respects copyright but also gives your readers the opportunity to examine methods and details for themselves. Example: 90 percent of Wikipedia authors are male (Bayer 2013).
