No. 9-806-105 in HBS. Harvard Business School Publishing, Boston, MA In-text citations in APA format include the author's last name, the year of publication, and the page number (for quotations), either in the text or in parentheses. For example, "O'Connor (1999) argues that..." You should also include the title of the article if it is available. So, "O'Connor claims that marketing is a social process" would look like this: O'Connor 1999, pp. 105-106. If you are citing multiple articles by the same author, you can list them individually or with a period between each citation. For example, "O'Connor (1999) claims that marketing is a social process; Jones (2000) asserts that companies must adapt to survive." If there is no title available for the article, such as for an op-ed, you can use the first word of the abstract instead. So, "O'Connor argues that marketing is a social process"; "Jones says that companies need to adapt to stay competitive." It is important to note that not all journals use APA style guidelines. If yours does not, then you will need to follow different instructions. However, most academic journals allow authors to write their own in-text citations, so knowing how to properly cite HBR articles will help you avoid confusion when submitting your work.
