Harvard referencing

Harvard referencing consists of two elements: an in-text reference to the source (publication), and a uniform bibliography at the end of the text. The two elements are linked.

Footnotes may be included in texts employing the Harvard referencing system – yet only factual or philological (lexical) non-biographical footnotes are allowed.

The reference shall be enclosed in parentheses, and include the following: the author’s last name, year of publication, and page number. If two authors with an identical last name are cited, the initial of the first name shall be added.

Examples of in-text citations

• Standalone publication, book by a single author: (Szymański 2009, p. 5)
• Work by two authors – sequence of names identical to the one in the book: (Szymański and Schreiber-Kurpiers 2010, pp. 12-14)
• Work edited by a specific individual: (Szymański ed. 1989, p. 101)
• Works by more than one author in a single reference: (Szymański 2003, pp. 17-55; Schreiber-Kurpiers 2006, pp. 13-22)
• Several works by one author in a single reference: (Szymański 2001, p. 45; 2004, p. 126)
• Work by multiple authors, of whom only the first (one) is listed, others merely indicated. This form of reference only be used for three or more authors: (Szymański et al. 2010, p. 3)

• When citing a source without the publication date given, the phrase “no date” or abbreviation “n.d.” shall be used. The phrase or abbreviation shall be applied in conformity to basic reference list setup rules: (Thoma n.d., p. 45)
