Explain Harvard formate of reference.

The Harvard referencing style, also known as the author-date system, is a widely used citation format that allows writers to acknowledge sources of information within their writing. In the Harvard style, citations include the author's surname and the publication year within parentheses, placed within the text of the document. A full reference list is provided at the end of the document, listing all sources cited in alphabetical order by author's surname.

In-text citations follow the format of (Author's Surname, Year), inserted immediately after the relevant information in the text. If the author's name is included in the narrative, only the publication year is enclosed in parentheses, e.g., "According to Smith (2019)…". If there are multiple authors, list them all separated by commas, e.g., (Smith, Jones, & Brown, 2018).

In the reference list, each entry begins with the author's surname followed by initials, followed by the publication year in parentheses. Next comes the title of the work, italicized or underlined, followed by publication information, including the publisher and place of publication for books, or the journal title, volume, and page numbers for articles. For example:

Smith, J. (2017). Title of Book. Publisher.

Jones, A., & Brown, B. (2018). Title of Article. Journal Title, Volume(Issue), page range.

In the Harvard style, proper citation of sources is essential for acknowledging the contributions of other authors, avoiding plagiarism, and allowing readers to locate and verify the information cited. It is important to ensure consistency and accuracy in formatting citations and reference lists according to the specific guidelines provided by the institution or publisher.
