This article teaches you how the Harvard-style citation format works and why it is important. The official Harvard citation format is designated to accurately describe research results. We’ll talk about how to properly label author information, year of publication, and how to cite books and papers. Citations are especially important for academic papers, and when used correctly they can increase the credibility of an article. In recent years, the Harvard style citation format has gained more and more attention, and its guidelines specify how to correctly label author information, publication year, and how to cite books and papers. We will analyse it in depth to help you use Harvard style citation format proficiently in essay writing.1. Standardise detailsHarvard style citation is usually in the form of ‘author’s name + year of publication’. If the author’s name has appeared in the sentence, only need to specify the year of publication on the line; if not, you need to put the author’s surname and year of publication in parentheses.2. Distinguish between multiple publicationsIf an author has multiple works or papers published in a year, it can be indicated by underlining A, B, C and so on.3、To deal with the situation of collaboratorsIf multiple authors are involved, the surname of the first author should be indicated first, and then the other authors should be indicated by leading etal.,in italics. In addition, if the work has two authors, the surnames of both need to be listed to avoid confusion. For example, the recent research article task1(year), co-authored by White and Brown, applies to occasions where the name of the second person is directly mentioned.4, arrange the citation orderThe citation should be arranged in alphabetical order of the author’s name, and articles by the same author should be arranged in the order of the year. For example, the research paper task1(year) by Jiang et al. shows that most authors try to …… Each citation note should have a substantive content or element and needs to be strictly categorised and managed.Book citations need to include the author’s last name (and sometimes the full name in initial capitals), publisher, place of publication, and title. In this case, short horizontal bars are used to connect the various parts of the information. For example, Baron, D. P., (year). Business and the Organization, Chester: Pearson.This canonical and detailed information can be easily shared through clear and standardised annotations.The role of citation notes is obvious: to help readers understand the article in depth, to confirm the source and authority of the data, and also to ensure that the author’s point of view can be effectively stated and to prevent plagiarism from occurring. Therefore, we should carefully learn and correctly use the Harvard style citation format and related rules to make academic research smoother!
