Different citation styles

Different citation styles exist because academic disciplines do not work in the same way. They differ in their research methods, the types of sources they rely on, and how they communicate knowledge.

Consequently, citation practices have evolved to address the requirements of individual disciplines, rather than being random collections of regulations. In the social sciences, author-date citation systems, such as APA and Harvard styles, emphasize the author's name and recency

Conversely, fields like engineering and medicine frequently adopt numeric systems, including IEEE and Vancouver styles, which utilize numerical citations to maintain textual brevity, particularly when references are abundant.

The humanities, characterized by more interpretive and discursive argumentation, often employ note-based systems like Chicago Style, which permit supplementary explanations alongside citations

However, despite these variations, all citation styles fundamentally fulfill the same core functions: acknowledging sources, promoting transparency, and allowing readers to trace and verify information.
