How to write References There are two main methods of referencing articles in journal and book publications : 1- Harvard ( author – date ) style. 2- Vancouver ( author number style )

Vancouver Style The list of references contains details only of those works cited in the text. The references are listed in the same numerical order as they appear in the body of the text

Harvard Style In an author-date style, a textual citation generally requires only the name of the author(s) and the year of publication (and specific page(s) if necessary). This may appear at the end of a sentence, before the full stop, e.g. It is futile to maintain that the sexes are interchangeable (Moir & Jessel 1991). It is futile to maintain that the sexes are interchangeable (Moir & Jessel 1991, p. 94).

Alternatively, the author’s surname may be integrated into the text, followed by the year of publication in parentheses. Examples: Moir and Jessel (1991) have shown that it is futile to maintain that the sexes are interchangeable. Moir and Jessel (1991, pp. 93-4) have shown that it is futile to maintain that the sexes are interchangeable.

If two or more works by different authors are cited at the same time, separate them with a semicolon. Example: The implications for land degradation have been much debated (Malinowski, Miller & Gupta 1995;Thomson 1999). A list of references contains details only of those works cited in the text. listed alphabetically
