The Harvard Referencing System, also known as the author-date system, is a widely used method for citing and referencing sources in academic writing. It's essential for maintaining academic integrity and giving proper credit to the sources you use in your research. Here's a simple guide to the Harvard Referencing System:

1. In-Text Citations:

In the Harvard system, you include in-text citations within the body of your text whenever you refer to or quote from a source. These citations consist of the author's last name and the publication year in parentheses. For example:

• (Smith, 2019) - For a book by an author named Smith published in 2019.
• (Johnson and Lee, 2020) - For a book by two authors named Johnson and Lee published in 2020.
• (Anderson et al., 2018) - For a book by multiple authors (more than two) named Anderson, Smith, and Johnson published in 2018.

2. Reference List:

At the end of your document or paper, you should include a reference list that provides full details of all the sources you cited in your work. Here's how to format the reference list:

For Books:

Author(s) last name, Initial(s). (Year). Title of the book. Publisher.

Example: Smith, J. (2019). The Art of Writing. Academic Press.

For Journal Articles:

Author(s) last name, Initial(s). (Year). Title of the article. Title of the Journal, volume number(issue number), page numbers.

Example: Johnson, A., & Lee, B. (2020). The Impact of Climate Change on Coastal Ecosystems. Environmental Science, 7(2), 123-135.

For Websites:

Author(s) last name, Initial(s) or organisation name. (Year). Title of the webpage or article. Website Name. URL

Example: Smith, J. (2018). How to Cite Sources Properly. Harvard Citation Guide. https://www.examplewebsite.com/citation-guide

3. Additional Tips:

• When there is no identifiable author for a source, use the title in place of the author in both in-text citations and the reference list.
• For sources with multiple authors, use "et al." in the in-text citation after the first author's name when there are more than two authors.
• If you are directly quoting a source, include the page number in the in-text citation, e.g., (Smith, 2019, p. 45).
• Always italicise or underline the titles of books and journals in your reference list.
• Organise your reference list alphabetically by the authors' last names.
• Be consistent in your formatting throughout your paper, following the same style for all citations and references.

Remember that proper referencing is crucial in academic writing to avoid plagiarism and give credit to the original sources that contributed to your research. Different institutions or publishers may have specific variations of the Harvard Referencing System, so it's a good idea to check your institution's guidelines or style manual for any additional requirements or variations.
