Because scholarship is a conversation, it's important to give attribution to the voices you are incorporating into your research. By doing that, you point to the work that has been done before you, you build credibility for your own contribution, and you provide a clear path for others to follow.
IMPORTANT: different journals across the four fields of anthropology use different citation styles. Check your syllabus to make sure you are using the correct citation style for your project. Below are links and resources for the most common citation styles used in anthropology.
The American Anthropological Association Publishing Style Guide follows the Chicago Manual of Style (Author-Date), 17th edition.
The American Journal of Biological Anthropology follows the Publication Manual of the American Psychological Association (APA).
