Most students and scholars learn the disciplinary conventions regarding citation and never think about them again. But citation practices vary widely both between and within disciplines, and once you’re past the dissertation, you have far more flexibility in choosing your own citation style than you think. To be sure, academic journals have their own house styles for articles. The 2009 style guide for all journals of the American Anthropological Association states: “All references must be cited in author-date form; all author-date citations must be referenced,” and the guide provides detailed instructions for how to use the author-date format for e-mails, websites, brochures, and other eclectic materials.
But where did these conventions originate and how did they come to anthropology? The standard of in-text author-date citation derives from something called the “Harvard style,” which originated in the field of zoology. In 1881, the zoologist Edward Laurens Mark published an important paper on the garden slug wherein he included the first parenthetical author-date citation. This system spread out from zoology to other natural sciences where the author’s name and the date of the publication are the two most important pieces of information. Prior to Mark’s invention of the author-date referencing system, footnotes were sprinkled randomly throughout the text and signaled by asterisks and other printer’s marks. The author-date system streamlined citations and favored brevity and clarity.
