The purpose of any citation is so that the reader can find the sources you used. In the reference list or bibliography section of your paper, the general format for citing an article is this:
Include the author(s), publication date, article title, journal title, volume and issue numbers (if applicable), and page numbers. If available, include the DOI (Digital Object Identifier) or permanent link to the article.
APA Style strongly encourages authors to cite the article's DOI, if available. Harvard Business Review articles generally do not have an assigned DOI. In this situation, it is okay to include "Retrieved from [database]" or "Retrieved from [permalink]." It is also okay omit the link altogether.
