About Harvard Style

Harvard citation style is also known as the author-date referencing style. This guide will show you illustrations of common Harvard citations, guides for extensive needs for Harvard citation and some recommendations on how to manage citations in general.

Do take note that there is some slight variability amongst Harvard citations, such as in the dates and authors field. Check with your professor, lecturer or publisher to clarify which Harvard citation format to use.

There are three parts to citation:

  1. In-text citations that appear in the body of your theses or arguments to show the source of the idea, which come in the form of direct quoting, paraphrasing, or summarizing. They usually appear in (author-date-page) format but there are variations.
  2. Reference lists or bibliographies found at the end of your theses or assignments.
  3. Footnotes have two uses. One is to take the place of in-text citations where the in-text citation will be replaced by a superscript number, and the in-text citation is relegated to the bottom of the page that the footnote is on. Another use of footnotes is to explain further a side idea that is not convenient to be expanded in the text as it breaks the continuity of the main idea's explanation. Usage of footnotes is dependent on requirements set by individual professors/lecturers and journals and are therefore optional in the Harvard citation system.

Harvard citation style is used typically in Social Sciences, Medical Sciences, Natural Sciences and Humanities. If you are not sure whether to use Harvard citation or other citation systems, please check with your lecturer or professor.

Harvard style guides

The Harvard style guides/manuals below provide instructions and examples of how to create footnotes and bibliographies in research papers. Some include advice on grammar and punctuation, research methods, and guidelines on formatting the final paper.
