Citation Style Guides
Academic citations come in many styles. While all citations fundamentally require at least Author, Year, and Journal, the specific citation style is dependent on your field of study, school guidance, or journal author guides. Below you will find guides for almost all major and niche citation styles complete with style-specific rules, examples, common mistakes, and links to the official guide.
